Default Parameters for CtxSDXInstancesTest

This test auto-discovers the VPX instances that the target NetScaler SDX appliance supports and reports the availability of each instance. If the test alerts to an instance unavailability, you can use this test to once again verify why that instance is inaccessible - is it because the instance is down or the VM hosting that instance is halted? The test also monitors the resource configuration of each instance and the percent resource consumption of every instance; in the process, the test points you to resource-hungry instances, and thus The uptime of each instance is also reported, so that administrators can promptly detect unscheduled instance reboots and unplanned instance downtime.

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

  • By default, the REPORT MANAGER TIME flag is set to Yes, indicating that, by default, the detailed diagnosis of this test, if enabled, will report the shutdown and reboot times of the SDX appliance in the manager's time zone. If this flag is set to No, then the shutdown and reboot times are shown in the time zone of the system where the remote agent is running.

  • 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.

  • 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.
