Default Parameters for CtxSDXXenDiskTest

This test auto-discovers the physical disks supported by the SDX appliance, and for each physical disk, reports the current capacity, space usage, and the I/O activity on that disk. In the process, the test points to the disks that are not sized commensurate to their usage. Based on the pointers provided by this test, administrators can then proceed to resize their storage.

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