Glossary

A

Application: A program developed to operate in conjunction with NNM. Applications can integrate with NNM to provide an open systems environment of management capabilities for administrators and a single appearance to users.

Application Plane: Submaps contain two layers, or planes, on which symbols are displayed: the application plane and the user plane.; The application plane displays symbols of objects that are managed by at least one network or system management application. Applications create objects and place the symbols of the objects on the application plane of a submap. One or more applications can manage the objects, and all symbols of objects that appear on the application plane.; Symbols of an object on the application plane appear without shading, directly against the submap background.; Alternatively, if the object is not managed by an application, the symbol appears on the user plane. NNM distinguishes symbols on the user plane by providing shading for symbols that makes them appear as if they are raised above the submap background.

Attribute: An object represents a resource by modeling the attributes (characteristics) of the resource. The full description of an object is a combination of the object attributes assigned to the object by NNM, by applications, and by operators and administrators. You can think of an attribute as a place holder in which a specific value is added to provide information about the values and state of the object. For example, the following table shows several possible attributes for an object representing a computer and a value for each of the attributes.

Object	Attribute	Attribute Value
a computer	IP Address	15.15.15.156
	IP Hostname	jdoe
	Status	Critical
	isComputer	True
	Vendor	hitachi

When you look at the Object Attributes list in the Add Object dialog box or the Attributes list in the Object Properties dialog box, you often see applications, such as IP Map, listed. These applications can assign object attributes. The attribute categories listed are:
: Capability--These attributes, such as isRouter and isDevice, determine what menu commands are dimmed (which commands are available based on the selected object).
: General--These attributes are not application specific. The Vendor attribute is an example of a general attribute.
: Application Name(s)-- Each application can define attributes for objects. For example, IP Map assigns several attributes to the node object, including: IP Hostname, IP Address, and IP Status.

Attribute Value: The specific value defined for a particular attribute.

Attributes List: A list that displays a list of attributes you may set for specific objects. These are global object attributes that are valid for an object across maps. The Attributes (or Object Attributes) list appears in the Add Object, Add Connection, and Object Properties dialog boxes. When adding or describing an object, you can view or modify the attributes associated with the object.

Auto Layout: Auto Layout disables or enables the layout algorithm for a single submap or for all submaps in the open map.; If you select Auto Layout, NNM arranges symbols added to the submap according to the layout algorithm chosen for the submap.; If you deselect this option, NNM creates a New Object Holding Area in the lower portion of the submap, and places symbols added to the submap in this area.

B

Background Graphic: A background graphic is a picture or graphic that has been added to a submap to serve as a background for the displayed symbols. Background graphics provide contextual information such as a floor plan for systems, a map of geographically diverse sites, etc. Each submap may have its own background graphic, assigned by either an application or by a user.
Behavior: A characteristic of a symbol that determines what happens when you double-click on the symbol with the mouse. Symbol behavior may be either explodable or executable.

Bus Layout: A layout algorithm that displays a bus configuration and shows symbols arranged along the bus in a snake-like backbone, which represents the linear array of nodes on a segment.

Top

C

Capabilities: Object attributes such as isRouter and isDevice that are used to determine menu dimming (which menu commands are available based on the selected objects).

Child Submap: The submap of an object represented by an explodable symbol. Objects with child submaps are called parent objects. Double-clicking the explodable symbol for a parent object opens the child submap, which displays the layer of the network hierarchy associated with that object.

Clipboard: A memory area where NNM temporarily stores symbols that are cut or copied. The Clipboard is used for cut and paste, or copy and paste, operations. You cannot directly view items in the Clipboard.

Comments: Textual information that you can enter in dialog boxes for maps, submaps, snapshots, and objects. You can include keywords in the object comments so that you can find meaningful subsets of objects with Find by Comments command.

Compound Status: Compound Status propagates the status of a symbol in a low-level submap to symbols in parent submaps to alert you to a problem. A symbol in one or more higher-level submaps changes color to alert you to changes in status of specific nodes on the network.; You can configure how compound status is determined using one of three schemes:; * Default; * Propagate Most Critical; * Propagate At Threshold Value; Compound status is defined for the entire map. You can set compound status in the New Map Wizard or the Map Properties dialog box.; Note that an application can implement a compound status scheme other than the default scheme set by NNM.

Connection Symbol: A special symbol type that connects two icon symbols (or an icon symbol and a backbone) on a submap. Once created, a connection symbol behaves the same as an icon symbol. You may display a label, open a symbol pop-up menu, change symbol behavior, etc. However, you cannot change its symbol type.; NNM provides the following registered connection symbols:; * solid line; * dot-dash line (Not available in the Network Presenter.); * dotted line (Not available in the Network Presenter.); * dashed line (Not available in the Network Presenter.); You can choose from these symbols in the Add Connection Palette. Connection symbols behave like icon symbols in the following ways:; * A connection symbol represents an object, just like an icon symbol.
: * Connection symbols may reside on the application plane or the user plane.
: * You can display a symbol pop-up menu for the connection symbol, and open the Symbol Properties dialog box to view symbol characteristics.; * You can assign a label to the connection symbol.; * The connection symbol is either explodable or executable (executable is not available in the Network Presenter).; A connection symbol may represent multiple connections between two icon symbols or an icon symbol and a backbone. In this case, double-clicking on the connection symbol opens a meta-connection submap which displays each connection.

Context Identifier: Use context identifiers to control the placement of menu commands and toolbar buttons. NoGeneric and NoDefault are reserved context identifiers. NoGeneric blocks pull-down menu items that include an AllContexts placement rule and symbol pop-up menu commands that include an Any placement rule.; You can assign submap context IDs to individual submaps using the APIs, the Submap Properties dialog box, or the New Submap Wizard (choose New or Properties from the Submap submenu in the Map menu).

Correlation: A correlation is a set of rules and calculations that can modify the flow of events in a particular way. Many correlations may be applied together. See also Event Correlation.

Critical Status: A status state displayed by a symbol that indicates a severe problem exists with the object and normal use is disrupted or severely impeded. This is the most serious alarm level. To interpret the meaning of critical status for a particular symbol, it may be helpful to know the status source for the symbol:
: If the status is compound status, it reflects a critical condition in the components of the parent object, as represented on the child submap.; If the status is set for the symbol or object, it may reflect a critical condition for the object itself.; The default color for critical status is red.

Cut: A command you use to cut selected symbols to the Clipboard. Selected symbols are deleted from the submap or submaps when you confirm the Cut command.; You can use the Cut command in conjunction with the Paste command to move symbols by pasting them from the Clipboard to a submap (cut-and-paste).

Top

An initial configuration setting. Defaults are supplied by NNM to reduce the amount of time required to start actively managing systems on your network. Users and applications can alter many default settings.

Default Compound Status

Default compound status causes NNM to propagate operational status in the following manner:

Condition of symbols in the child submap	Status of symbols of the parent object
No normal or abnormal	Unknown
All normal	Normal
One abnormal and all others normal	Warning
Multiple abnormal and multiple normal	Minor
One normal and all others abnormal.	Major
All abnormal	Critical

Default Map

A map automatically created and opened by NNM when you run it the first time. The default map is used when no other maps exist.

Delete

A command you use to delete symbols. Selected symbols are deleted from a submap or submaps after you confirm the Delete command. In contrast to the Cut command, the Delete command does not add the deleted symbols to the Clipboard. You cannot paste deleted symbols back onto a submap.

An application may deny a Delete command. In this case, an alert box notifies you that you cannot delete the object of the symbol. You can hide the symbol, however.

Dictionary

A data type used to set correlation parameters. A dictionary data type is displayed as a table of named values.

Disabled Status

An administrative status state displayed by a symbol that indicates the object is inactive or administratively not available. There may or may not be something wrong with the object. The idea is that an administrator has taken the object offline.

In the case of MIB II, an interface can be disabled so that it is not available for routing. An interface may be disabled because it is down for a long period or because the administrator does not want to route traffic to some network.

The default color for disabled status is dark brown.

Display Legend

A legend of the types of icon symbols you may add to submaps. The display legend shows you the symbol classes and subclasses. The legend also displays the current status colors.

Dynamic Parameter

A correlation parameter that can be changed while a correlation is enabled. Contrast with Static Parameter. See also Parameter.

E

ECS: HP OpenView Event Correlation Services.

Event Correlation Services: A graphical user interface module in NNM for controlling the ECS Engine. See also ecsmgr.

ECS Engine: The HP OpenView ECS runtime process that correlates events in accordance with the enabled correlations.

ecsmgr: A command line utility for controlling correlation. May be used to create new correlated event streams.

Event Correlation: Event correlation modifies the flow of events by recognizing patterns of events and replacing them with a single, more meaningful, event. See also Correlation.

Exact Match: In Find commands, you may use either of two matching schemes: pattern matching or exact match. Finding by exact match compares the input string you want to search to the complete target string. Find by Label uses exact match to find symbols.
You can use either exact match or pattern matching in Find by Selection Name or in Find by Attributes if the attribute is of type string.

Exclusive Submap: A submap that is created by an application with exclusive rights of control. If an application creates a submap as an exclusive submap, only that application can determine what happens in the application plane of the submap.

Executable Symbol (not available in the Network Presenter): A symbol configured such that double-clicking on it causes an application to perform an action on a set of target objects. When you change the behavior of a symbol to executable, you choose from a list of registered applications and actions, and you choose a set of objects (target objects) that the application acts upon. You can modify these settings at any time.; Executable symbols are useful for automating network management tasks that you want to perform on specific objects. The executable symbol enables quick access to program or application execution.; You can distinguish an executable symbol from an explodable symbol by the raised square around the executable symbol.

Explodable Symbol: A symbol configured such that double-clicking on it displays the child submap of the parent object that the symbol represents.
: The child submap displays the components of the parent object. If the object has no child submap, you can create a new submap. You can given the choice to create the submap with default settings, or to create and configure a new submap by modifying the default settings with the New Submap dialog box.; Once the submap is created, double-clicking on the symbol opens the child submap.

G

General Attributes: Attributes associated with all objects on a map. You can display these attributes in the General Attributes dialog box. To open this dialog box, select Edit:Object Properties.

Top

H

Hide: A command you can use to hide selected symbols from a single submap or from all submaps of the open map. The symbols still exist, but they are not displayed in the submap. Hidden symbols do not contribute to compound status and do not receive status updates. However, Find commands will search for and list objects of hidden symbols.; If a submap contains hidden symbols, the status bar of that submap displays the number of hidden symbols. You can redisplay all hidden symbols in a particular submap using the Hidden Objects menu command from the View menu from NNM on the Windows NT operating system or on a UNIX system.; The Hide command is useful when you no longer want to display a symbol and an application refuses to allow NNM to delete a symbol, or the symbol reappears after a delete because the object is rediscovered.

Highlighting: Objects are highlighted as a result of an operation by NNM or an application. Highlighting is a common way for applications to represent the output of some operation.; Highlighting is indicated by displaying inverse video in the label of all symbols of the highlighted object. For example, the Find command identifies found objects by highlighting the symbols of the object. The object, not the symbols, is considered highlighted.

Top

I

Icon Symbol: NNM uses two types of symbols in submap windows, icon symbols and connection symbols. The most common type is the icon symbol, usually just called symbol. You can choose from an variety of predefined icon symbols. Applications can also display predefined symbols on submaps.; The icon symbol is composed of classes and subclasses. The class refers to the outer shape of the symbol, and the subclass refers to the graphic (or icon) inside the outer shape. Together, the class and subclass of the submap makes up the symbol type.; All the registered icon symbols are displayed in the Display Legend dialog box.; By contrast, connection symbols appear as lines that connect icon symbols. Both icon symbols and connection symbols may represent the same object. For example, an IP interface object may be represented by an icon symbol in one location, and a connection symbol in another submap.

Independent Submap: A submap that has no parent object associated with it and which is independent of any existing hierarchy of submaps.

L

Label: You may assign a label to any symbol. The label does not need to be unique. The label is displayed underneath a symbol. You can assign, modify or inhibit the display of a label at any time using the Symbol Description dialog box. Both icon symbols and connection symbols may have labels.

Layout: Refers to NNM's Auto Layout feature, which arranges symbols on a submap according to a layout algorithm. If automatic layout is selected for a submap, Auto Layout appears in the status bar of the submap window.

Layout Algorithm: A program that determines how NNM arranges symbols on a particular submap. From NNM on the Windows NT operating system or a UNIX system, you can choose from several layout algorithms:
: * Point-to-point; * Star; * Bus; * Ring; * Row/Column; * No Layout; You can select or deselect the Auto Layout option for the current submap in the open map, or for all submaps in the open map.; After selecting (or deselecting) Auto Layout for all submaps in an open map, you can change the setting for specific submaps.

Top

M

Major Status

A status state displayed by a symbol that indicates some kind of problem with the object. The severity of the problem is relatively high and normal use of the object is likely to be impeded. To interpret the meaning of major status for a particular symbol, it may be helpful to know the status source for the symbol:

If the status is compound status, it reflects a major condition in the components of the parent object, as represented on the child submap.

If the status is set for the symbol or object, it may reflect a major condition for the object itself.

The default color for major status is orange.

Managed Object

An object that is being actively managed. Applications can monitor and manage objects for topology, status, and configuration changes. A managed object displays its status on submaps of the open map.

When you choose to manage an object, the objects in child submaps of the managed object also become managed. An object can be toggled between managed and unmanaged. You can choose which objects to manage, so that you can customize the management region for any map.

* See Unmanaged Object

* See Management Region

Management Region

The set of managed objects on a particular map that defines the boundaries of the network that is being actively managed. The management region may vary across maps.

Map

A map is a conceptual layout of your network and its systems. You can define properties for a map, but you cannot view it directly; instead, you view the submaps that comprise the map. The submaps are organized hierarchically and display different parts of your network using graphical symbols.

You can use different maps to define different management regions or for different presentations of the same management region. You can tailor different maps to the needs of individual users. A given user can setup different maps for different purposes.

NNM always has one map open. The map chosen as the User Default Map opens when you run NNM. You can open other maps from the Maps dialog box. With NNM, you can:

* Create new maps.
* Copy existing maps.
* Modify the configuration of a map and the configuration of applications used with the map.
* Delete maps.
* Take snapshots of maps.

Map Applications

Applications that create or modify the contents of maps. Map applications may dynamically update the open map to reflect the state of systems on the network and provide information about objects in the map. For example, IP Map manages objects that represents IP addressable systems.

Map Permissions

Provide security control for access of network maps. Maps can be assigned read-write access, read-only access, or no access by using the file permissions of the operating system on which NNM runs.

A user may have read-write permission for a map, but may open the map with read-only access. This occurs if another user has the map open with read-write access or if the user starts a NNM session with the -ro (read-only) option. Only one user may have a particular map open with read-write access at any one time.

Meta-Connection Symbol

A submap that displays multiple connections between two symbols or a symbol and a backbone. This submap is automatically created when you, or an application, adds an second connection between two icon symbols, or an icon symbol and a backbone. The meta-connection submap displays all the connections between the two symbols as you add additional connections between the two symbols (or symbol and backbone) on the submap.

You can open a meta-connection submap by double-clicking on the connection symbol that represents the multiple connections.

Minor Status

A status state displayed by a symbol that indicates a problem of relatively low severity and should not impede normal use of the object. The terms marginal and minor are aliases for the same state.

To interpret the meaning of minor status of particular symbols, it may be helpful to know the status source for the symbol:

If the status is compound status, it reflects a minor condition in the components of the parent object, as represented on the child submap.

If the status is set for the symbol or object, it may reflect a minor condition for the object itself.

The default color for minor status of icon symbols and connection symbols is yellow.

Top

N

Name: Names are assigned to various NNM elements, such as objects, maps, submaps, snapshot, and symbols. NNM handles the names of these elements slightly different.; Object names; * Selection name is mandatory.; * Additional name attributes are optional. Applications may use specific naming schemes to identify an object. For example, IP Map identifies objects via an IP hostname. If IP Map is managing an object, the object will have an IP hostname and a selection name.; * NNM uses the selection name as a unique identifier.; * Every name attribute is unique in its name space (for the type of name that it is).; Map names; * Mandatory.; * Must be unique.; * NNM uses the map name as a unique identifier.; Submap names; * Optional.; * Does not need to be unique.; * NNM uses a submap's place in the map hierarchy as an identifier.; Snapshot names; * Mandatory.; * Not necessarily unique.; * NNM uses the time of creation as the unique identifier.; Symbol names
: * Optional.; * Not necessarily unique.; * NNM uses the mouse pointer as the unique identifier.

New Object Holding Area: The portion of a submap that displays symbols of objects added to a submap with no layout algorithm or with Auto Layout deselected for the submap. You can move symbols from the holding area to the main part of the submap.

Normal Status: A status state, displayed by a symbol, that indicates an object is functioning normally. There are no events or alarms to indicate that there are any problems with the object. The object represented by the symbol can be contacted by the application and is responding appropriately.; To interpret the meaning of normal status for a particular symbol, it may be helpful to know the status source for the symbol:; *If the status is compound status, it reflects a normal condition in the components of the parent object, as represented on the child submap.; * If the status is set for the symbol or object, it may reflect a normal condition for the object itself.; The default color for an icon with normal status is green. The default color for a connection with normal status is black.

Top

O

Object: An object represents a logical or physical entity or resource, or group of such physical entities that exist in the network. Examples of objects are a network, a computer, an interface, and a process.; NNM graphically represents objects by displaying a symbol on a submap. An object may be represented by multiple symbols across multiple submaps and maps. NNM identifies an object by its selection name. NNM and applications manage an object by its attributes.

Object Attribute: An object attribute is a single characteristic of an object. In NNM, an object is defined by its attributes.; Some object attributes are set or monitored by specific applications. The Object Attributes list in the Object Properties dialog box includes these applications so that you can view attribute values for an object.; For example, IP Map determines IP addresses and displays the value of this attribute for all nodes that it manages.

Object Status Source: A setting that allows applications to set the status of a symbol based on the status of the object. All symbols of the object whose status source is Object Status Source exhibit the same status within the open map.

Operational Status: The operational status of a particular symbol represents the status of certain object attributes, or characteristics, as defined by the managing application. NNM uses colors displayed on symbols to report status to you.; unknown-- The symbol's current status has not yet been determined by the managing application.; normal-- The symbol is functioning as intended and responding appropriately when contacted by the managing application.; abnormal--The symbol is given one of the four abnormal status conditions (warning, minor/marginal, major, or critical), and is either potentially or currently having problems.

P

Parameter

In ECS, a correlation parameter controls some aspect of a particular correlation. Different correlations have different parameters. The correlations themselves describe parameter settings.

Parent Object

Refers to the relationship that an object has with its child submap. In NNM, the only way to associate an object with a child submap is to create that child submap by double-clicking an explodable symbol for the object.

In NNM on the Windows NT operating system or a UNIX system, if the object does not already have a child submap attached to it, you are given the choice to create a child submap, with either default settings or modified settings. If you choose to modify the settings, the New Submap Wizard appears. The name of the parent object is displayed in the Parent Object field.

All explodable symbols of a parent object open the child submap when you double-click them. Symbols of a parent object can appear on multiple submaps. Therefore, you can open a child submap from any submap that contains an explodable symbol of the parent object.

Parent Submap

The default parent submap is the parent submap from which the child submap was created in the first place.

A parent object may be represented by symbols residing on multiple submaps. In this case, any of those submaps can be assigned as the parent submap.

Pattern Matching

In Find commands, you may use either of two matching schemes: pattern matching or exact match. Finding by pattern matching enables the user to provide a regular expression (or simple substring) for the input string.

Symbols or objects containing the target string that matches the substring or expanded regular expression is displayed by NNM.

Pattern matching is useful for finding sets of objects by address or by keywords embedded in assigned comments.

Point to point Layout

A layout that shows an arbitrarily interconnected set of symbols.

R

Read-Only Access: In NNM, read-only access refers to map access and map permissions. access. In a map open with read-only access you can displays status, navigate through its submaps, display snapshots, and monitor and find objects.; You can choose Refresh from the Map menu to update the topology of a map open with read-only access. However, you cannot add, delete, or modify objects, symbols, submaps, and snapshots.

Read-Write Access: In NNM, read-write access refers to map access and map permissions. A map open with read-write access is continuously updated with status and topology changes.; Read-write access allows you to add or delete objects, symbols, submaps, and snapshots within the map.; Only one user can have a map open with read-write access at a given time. Therefore, if another user already has the map open with read-write access, you can open the map only with read-only access.

Restricted Status: An administrative status state displayed by a symbol that indicates the object is operating normally but is no longer available for general use. It has been designated as inaccessible for some or all users and uses. The status of the object will not be propagated to the status of objects that are higher in the object hierarchy as long as it is in this state. The status of this object will be updated if a problem is detected while it is in this state. Once in a new state, the object's status will contribute to status propagation.; The default color for restricted status is tan.

Ring Layout: A submap layout algorithm in which symbols are arranged in a ring. A ring layout is one of several layout algorithms that are available in NNM.

Root Submap: A standard, top level submap, which exists for every map. The root submap is automatically created when a map is created.; Applications can add root-level objects to the root submap that, when exploded, display the highest level of a submap hierarchy. For example, the IP Map application places an internet symbol on the root submap. You can double-click the internet symbol to display an internet submap.; You cannot delete the root submap. The default layout algorithm of the root submap is row/column.

Row/Column Layout: A layout algorithm in which symbols are arranged in rows and columns.

Top

S

Selection: Selection is an action you perform. It identifies the symbol to which you want commands or other operations applied. You can select or deselect a symbol in the scoping pane or content area. NNM indicates that a symbol is selected by shading the symbol.; Selection is not the same as highlighting. Highlighting is performed by applications. It is a common way for NNM or an application to represent the output of some operation. The Display Legend illustrates the appearance of a symbol for a selected object and a highlighted object.
Selection Name: NNM identifies an object by a unique name called a selection name. All objects must have one. When you create an object, you assign a selection name to it in the Add Object dialog box. You can change this name at any time. If you do not assign a selection name, NNM uses the symbol label, or if no label exists, prompts you for a selection name.; Network applications, such as IP Map, also assign selection names. When NNM is installed, these applications assign selection names to the devices and entities they discover on the network.

Shadowing: NNM uses shadowing to distinguish symbols of objects on the user plane from those on the application plane. If an object is not managed by an application, the symbols of that object appear on the user plane. The symbols of that object project a shadow, making the symbols appear raised.
Shared Submap: Refers to a submap on which multiple applications may manage objects on the application plane. Shared submaps allow applications to cooperatively contribute information to the same submap.

Snapshot: A snapshot is a particular map frozen in time. You can create several snapshots of a map and display any one of them next to the open map.; A snapshot is useful for keeping a record of the previous condition of the network. Snapshots are read-only, and they do not receive any updates from applications.

Star Layout: This is a submap's layout presentation where the symbols are arranged in a star.

Static Parameter: In ECS, a correlation parameter that is loaded when a correlation is enabled. Contrast with Dynamic Parameter. See also Parameter.

Status: In ECS, the current status of a correlation. Usually Enabled or Disabled, but may be set to Input Enabled or Output Enabled.

Status Source: This is the source of the status being collected, propagated, or displayed. The source of status may come from:; * An application that sets status on a specific symbol. Called Status Source.; * An application that sets the same status on all symbols of a given object. Called Object Status Source.; * Compound Status.

Stream: A distinct flow of events. All streams originate from a common input. However, the network administrator may set up separate correlation streams to produce events for output to a specially configured Alarm Browser, or other application.

Submap: A submap is a collection of related symbols that are displayed in a single graphical window. Each submap displays a different perspective of the information in the map. Applications and users determine the contents of submaps.; The most common method you can use to navigate through submaps is by double-clicking the mouse on symbols called explodable symbols. Double-clicking on an explodable symbol causes a child submap to be displayed, if a child submap has been created. You can also open a submap by using the Up One Level and Top of Hierarchy buttons in the button panel of each submap window.

Submap Context: Menu and toolbar items can be targeted for display on submaps based on the purpose or context of the submap, but submaps can filter which menu and toolbar items are actually visible.; When a submap is created, the IP Map application sets its context. The submap context is a list of context identifiers. For example, a particular submap intended for printer management might have a context of wantPrinterMenus, NoGeneric. This submap context would limit menu commands and toolbar buttons to those that were targeted using the wantPrinterMenus context identifier.; The context expressions are defined in the application registration files or by the APIs.; HP OpenView applications can assign submap context IDs to individual submaps. You can also assign context IDs from the Context tab in the Submap Properties dialog box.
Symbol: A graphical representation of an object in NNM. Symbols come in two varieties: icon symbols and connection symbols. The term, symbol, usually refers to an icon symbol.; Symbols behave in one of two ways when you double-click them. They explode into a child submap, or they execute an application on a set of target objects (execute is only available in NNM on the Windows NT operating system or a UNIX system).

Symbol Class: Symbol types are classified by class and subclass. A class represents a collection of symbols with the same or similar properties.; A symbol class is represented by the shape of the symbol. Each symbol subclass in a given class contains the same shape. Each symbol class has a unique set of subclasses associated with it.

Symbol Status States: A symbol can convey the status of one or more components of a managed object. NNM supports 10 status states that are grouped into two categories: administrative and operational. Within the operational category, status states are further categorized as normal or abnormal.; The following four administrative status states are supported:
: * unmanaged; * restricted; * disabled; * testing; There are six operational status conditions. The first two are considered normal states and the last four, abnormal.; * unknown; * normal; * warning; * minor; * major; * critical; Each status condition is displayed on a submap by a certain color. Status colors are configurable. Some of the default colors do not exist in the resource database; therefore, RGB values are specified. However, the name of the color that best describes the RGB values is provided. The default values for the icon and connection symbols for a particular state may be different.

Symbol Subclass: Symbol types are classified by their class and subclass. For example, in the symbol class called Computer, the subclasses are PC, Workstation, Mini, and Mainframe.; All symbols in the same class have the same outer shape. NNM represents a symbol subclass by a graphic inside the class shape.

Symbol Type: A symbol is defined by its type. The symbol type consists of the symbol class and the symbol subclass.; The symbol class is identified on submaps by the outer shape of the symbol and the symbol subclass by the graphic inside the shape.

Top

T

Target Objects: Objects targeted for some action by an application. When you set the behavior of a symbol to executable, you choose an application to perform an action on a set of objects, called target objects. You can determine which objects will be targeted by the application. Each executable symbol may have its own set of target objects.; If you do not assign any target objects, the object of the executable symbol is used as the target.

Testing Status: An administrative status state displayed by a symbol that indicates the object is undergoing temporary diagnostic or maintenance procedures that may affect its performance or may interfere with its normal use. The status of the object will not be propagated to the status of objects that are higher in the object hierarchy as long as it is in this state. The status of the object will be updated if a problem is detected while it is in this state. Once in a new state, the object's status will contribute to status propagation.; The default color for testing status is salmon.
Token: A data type used to provide a choice of discrete values in a correlation parameter. For example, Yes or No.

Top

U

Unknown Status: The status of an object that is not known. The default icon symbol color for unknown status is blue. The default connection symbol color is Black.

Unmanaged Object: An object that is not actively managed. An unmanaged object displays status as Unmanaged. It does not display an active status (normal, warning, marginal, major, or critical). Unmanaged objects do not display compound status nor do they contribute to compound status. Status information on this object will not be maintained. Applications that provide status information will not continue polling this object.; You may choose to keep objects unmanaged when they are outside your area of interest, that is, outside the management domain of the open map.

Unmanaged Status: The status that indicates that an object is unmanaged. The default icon symbol color displayed to indicate unmanaged status is off-white. The default connection symbol color displayed is Black.

Warning Status: A status state displayed by a symbol that indicates a condition exists that could potentially cause a problem with the object. While the managed object is functioning as it is intended to function, there has been an event or alarm to indicate that conditions exist that could potentially cause a problem. To interpret the meaning of warning status for a particular symbol, it may be helpful to know the status source for the symbol:; If the status is compound status, it reflects a warning condition in the components of the parent object, as represented on the child submap.; If the status is set for the symbol or object, it may reflect a warning condition for the object itself.; The default color for warning status is cyan.
