Configuration of CtxXcXAWemCpuTest

To obtain a clear picture of the impact of CPU management features of WEM on XenApp / XenDesktop VM performance, you can use the CtxXcXAWemCpuTest test. This test reports the total number of processes and the unique processes that are affected by CPU spike protection feature. These metrics help you find out how many CPU-intensive processes are currently running in the environment. In the process, this test also reveals the configured CPU usage limit, how long the CPU usage limit is being violated by the processes and how long the processes are at lower priority due to violation of CPU usage limit. This way, the test alerts you if the priority of any process has been reduced because of CPU Spikes Protection. Besides, this tests also captures the count of processes that have been throttled owing to CPU clamping.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. By default, this is 5 minutes.

• Specify the HOST at which this test is to be configured.

• Specify the PORT at which the HOST listens. By default, this is set to 1494.

• The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

• To make diagnosis more efficient and accurate, eG 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, by default, for a particular server, choose the On option against DETAILED DIAGNOSIS. 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 bad and normal frequencies configured for the detailed diagnosis measures should not be 0.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
