Threshold values Threshold settings for the various subsystems enable PMP analysis adjustment to account for highly variable or stable system performance. A higher value used results in smaller average changes in performance. A higher value used also generates fewer performance bottleneck indications for a server whose performance changes dramatically. A smaller value can be used for servers with more stable performance or when the sampling rate is higher. Manual Log Purge Manual Log Purge enables the recorded sessions for a logged server or network storage enclosure, logged in the PMP performance database and occupying hard disk storage space, to be deleted. Use this tool regularly to remove unwanted recorded sessions and reduce database size. To delete records in the performance database: 1. From the Systems Insight Manager console toolbar, select Options→Performance Management Pack Options→Manual Log Purge. 2. Select the server or network storage enclosure for which to delete logged data. 3. Specify to delete data older than a specified number of days or a specified date. NOTE: Data acquired for the current date of the analysis server cannot be deleted. 4. To remove the data from the performance database, click Delete Selected Data. 74 Monitoring and controlling servers

Manual Log Purge enables the recorded sessions for a logged server or network storage enclosure, logged

regularly to remove unwanted recorded sessions and reduce database size.
To delete records in the performance database:
1.
From the Systems Insight Manager console toolbar, select
Options

.
2.
Select the server or network storage enclosure for which to delete logged data.
3.
Specify to delete data older than a specified number of days or a specified date.
NOTE:
Data acquired for the current date of the analysis server cannot be deleted.
4.
