Default Parameters for CtxSDXXenCPUCorTest

The CtxSDXXenCPUTest test alerts administrators to abnormal CPU usage on an SDX appliance, which can typically be caused by one/more CPU cores being utilized excessively. The question now is, which CPU cores are contributing to the CPU contention. The CtxSDXXenCPUCorTest test answers this question by reporting the average CPU usage of each CPU core of an SDX appliance.

This page depicts the default parameters that need to be configured for the CtxSDXXenCPUCorTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• To monitor a NetScaler SDX device, the eG agent should be configured with the credentials of a user with read-only privileges to the target device. Specify the credentials of such a user in the SDX USERNAME and SDX PASSWORD text boxes.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• The eG agent collects performance metrics by invoking NITRO (NetScaler Interface Through Restful interfaces and Objects) APIs on the target NetScaler SDX device. Typically, the NITRO APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the NITRO APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target NetScaler SDX device is not SSL-enabled, then the NITRO APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No.

• Once the above values are provided, click on the UPDATE button to 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.
