The OS Details test reports additional system-related metrics pertaining to the target system.

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 : Any host

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every host 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.
Process limit	The Process limit determines what type of processes are to be included in the detailed diagnosis of the Processes count measure of this test. By default, 5 is the Process limit. This implies that the detailed diagnosis of the Processes count measure will by default list only those processes for which more than 5 instances are currently running on the target host. Processes with less than 5 currently active instances will not be displayed in the detailed diagnosis. This limit can be changed.
Exclude process	If you want to exclude one/more processes from the detailed diagnosis of the Processes count measure, then specify a comma-separated list of processes to be excluded in the Exclude process text box. By default, the svchost process is excluded from the detailed diagnosis of this test.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Processes count	Indicates the number of processes running on the system.	Number	The detailed diagnosis of this measure will list the processes that are currently running and the number of instances of each process that are running.
Context switches	This value is the combined rate at which all processors on the computer are switched from one thread to another.	Switches/Sec	Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher priority ready thread, or switches between user-mode and privileged (kernel) mode to use an Executive or subsystem service. If the context switch rate is unusually high, it implies that there is excessive contention for CPU resources.
