What's New in Network Node Manager 6.01 Runtime Release

For more details about the following features, see the NNM documentation set or the extensive information under NNM's Help menu item.

NNM 6.01

• New capability in xnmgraph to automatically configure data collections for the data currently being shown on the graph.  Use the File->Configure Data Collector... menu item.  Only the new items being configured are shown in the xnmcollect GUI when this operation is performed, but on a save the new items become part of the normal collections stored in snmpCol.conf.
• New capabilities have been added to perform many functions on interfaces as well as entire nodes. Both xnmgraph and rnetstat now support invocation for a specific interface (not just a node).  This is especially helpful in xnmgraph when the node may have many interfaces.  rnetstat now has special capabilities for gathering information specific to an interface.  Thus, all of the standard menu items under the Performance, Configuration, and Fault menus can now be invoked on a selected set of Interface objects, not only on a selected set of Node objects.  In addition new pop-up menu items for Interface objects have been added to quickly obtain status information.
  To see this new functionality, rather than selecting a node symbol, instead select a line between two symbols or drill down into a node and select one or more of the interfaces.   Then select one of the menu items to view status or statistics, for example: Configuration->Network Configuration->Interface: Properties or Performance->Network Activity->Interface->Traffic->Utilization
• rnetstat now supports many new options for inquring about various aspects of a node or interface.  New functionality includes support for quering Frame Relay, DS1/DS3, ATM and SONET MIBS.  See the rnetstat.1 man page for details.
• New support in xnmgraph (and a helper executable 'ovexprguru') to do "smart" graphing of various statistics based on the configuration of the particular device being graphed.   For example, you can now see a utilization graph which for Full Duplex interfaces shows input and output rates as separate lines, but Half Duplex interfaces are graphed as a single line.  These enhancements support the proper use of high speed counters.   See the ovexprguru.1 man page for more details.
• In conjunction with the above functionality many new expressions are shipped as part of mibExpr.conf.
• The NNM installation is now split into three main phases.  First the Event Correlation Services, then the OpenView SNMP Agent (and corresponding man pages), and lastly Network Node Manager itself.
• Four documentation fileset names have changed within the OVNNMgrDOC product to support a 14 character naming convention.  OVNNM-WEL-ENGDOC, OVNNM-WEL-JPNDOC, OVNNM-DEV-ENGDOC, and OVNNM-DEV-JPNDOC have been changed to OVNNMWELENGDOC, OVNNMWELJPNDOC, OVNNMDEVENGDOC, and OVNNMDEVJPNDOC respectively.

NNM 6.0

• Event Correlation Services (ECS)
  Event correlation improves the information content of alarms in NNM's Alarm Browser by removing unwanted, redundant alarms and by adding new, more informative alarms.

• New indicator for correlated events
• New View:Show Correlated Events to view the alarms suppressed by the Event Correlation Services.
• The event browser (xnmevents) has been renamed 'Alarm Browser' in support of NNM's new operational model for alarm management, and menu items have changed from 'event' to 'alarm'.
• Simpler Licensing
• Node locked only (netls) license server no longer used.
• Licenses can be requested over the World Wide Web.
• Performance improvement by not adding unmanaged nodes past licensed limit.
• Remote Console Support
• Remote Consoles running NNM on Windows NT can now communicate with NNM management stations running on either UNIX or Windows NT

• Collection Station Support
• Management stations running on Windows NT can now receive distributed data from Collection Stations running on either UNIX or Windows NT
• The ovrepld service (background process) that listens for Collection Stations is not automatically started on a fresh installation.  It is only started after the first xnmtopoconf command establishes a Collection Station.
• Automatic management station/Collection Station failover
• Management stations will take over status polling for any Collection Station that is no longer reachable
• Once the Collection Station is reachable again, the management station will automatically release status polling for the nodes reported by the Collection Station
• A failover filter controls which objects assigned to a Collection Station will be status polled by the management station during failover
• DHCP support
• Ability to designate a bank of IP addresses as DHCP leased nodes, allowing NNM to intelligently handle the changing MAC addresses, configurable through Options:Network Polling Configuration dialog box.
• Events added to the OpenView MIB (.1.3.6.1.4.1.11.2.17.1) for informing NNM about DHCP node leases: OV_DHCP_Alloc and OV_DHCP_Release
