Unix Tables Test

This test monitors critical process, inode, file, and lock tables. If any of these tables reach the OS-specified maximum limit, application programs that use these tables will start to fail. Hence, monitoring the utilization of these tables on a periodic basis is critical.

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
Process table size	Indicates the number of process entries (proc structures) currently in use.	Number	This measure will not be available for Linux systems.
Process table maxsize	Indicates the maximum number of process entries that can exist (the max_nprocs OS parameter setting)	Number	This measure will not be available for Linux systems.
Process table utilization	Indicates the percentage of process entries in use currently.	Percent	A value close to 100% indicates that the system could be running out of process table entries. This measure will not be available for Linux systems.
Inode table size	Indicates the number of inodes in memory currently.	Number
Inode table maxsize	Indicates the number of inodes currently allocated in the kernel.	Number	This measure will not be available for Linux systems.
Inode table utilization	Indicates the percentage of inodes in memory out of the total currently allocated in the kernel.	Percent	This measure will not be available for Linux systems.
File table size	Indicates the number of entries in the open file table.	Number
File table maxsize	Indicates the size of the open file table in the kernel.	Number
File table utilization	Indicates the number of entries in the open file table as a percentage of the file table size.	Percent
Lock table size	Indicates the shared memory record table entries currently used.	Number	This measure will not be available for Linux and HPUX systems.
Lock table maxsize	Indicates the shared memory record table entries allocated in the kernel.	Number	This measure will not be available for Linux and HPUX systems.
Lock table utilization	Indicates the number of shared memory record table entries currently used as a % of the total number of entries for this table allocated in the kernel.	Percent	This measure will not be available for Linux and HPUX systems.
