Methods for Condensing a Performance Monitor Log File

MORE INFORMATION

• Use a file compression program, such as WinZip, to compress the log file. Performance Monitor log files compress very well using such utilities. This method is useful when you need to retain the entire contents of the log file.
• Relog the log file after resizing the time window. This method is useful when you are interested in only a specific time frame captured within the log file. An example of this is when you maintain weekly Performance Monitor logs, but are interested in reviewing only one of the days from one of the weekly logs. See "Relogging Input Log Files" in Performance Monitor Help for more information on relogging a log file with a modified time window.
• Relog the log file after limiting the number of objects to be logged. This method is useful when you are interested in only a specific subset of objects collected in a log. An example of this is when you maintain regular complete logs (all objects included) but are interested in reviewing only the memory usage from a particular log. See "Relogging Input Log Files" in Performance Monitor Help for more information on relogging a log file with a reduced object set.
• Relog the log file after increasing the update interval. This method is useful when you are interested in overall trends over the log file time frame. An example of this is when you maintain regular complete logs at ten minute update intervals, but wish to see only hourly samples over a particular log's time frame. See "Relogging Input Log Files" in Performance Monitor Help for more information on relogging a log file. After you have set up to relog a log file, select Log from the Options menu and then increase the number found in the Periodic Update Interval field.
