Paging Test

This test monitors memory paging in/out activity, and can provide early warning indicators of system memory bottlenecks.

This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick the desired Component type, set Performance as the Test type, choose the test from the DISABLED TESTS list, and click on the << button to move the test to the ENABLED TESTS list. Finally, click the Update button.

Target of the test : A Solaris, Linux, or HPUX system only

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every server being monitored

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The host for which the test is to be configured.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Pageout requests:	Indicates the page-out requests/sec.	Reqs/Sec	This measure will not be available for Linux systems.
Pages swapped out:	Indicates the pages paged out per sec.	Pages/Sec	This measure will not be available for HPUX systems.
Pages freed:	Indicates the pages freed out per sec by the page scanner.	Pages/Sec	This measure will not be available for Linux and HPUX systems.
Pages scanned:	Indicates the pages scanned by the page daemon as it looks for pages used infrequently.	Pages/Sec	If the page daemon scanning rate stays above 200 pages per second for long periods of time, then a memory shortage is likely. This measure will not be available for Linux and HPUX systems.
Ufs inodes removed:	Indicates the percentage of UFS inodes removed from the free list while still pointing at reusable memory pages. This is the same as the percentage of igets that force page flushes.	Percent	This measure will not be available for Linux and HPUX systems.
