SDX VPX Instance Status Test

To quickly identify the number and names of VMs and VPX instances that are operating on an SDX appliance and to rapidly determine their status, use the SDX VPX Instance Status Test.

Target of the test : A NetScaler SDX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the target NetScaler SDX.

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.

SDX Username and SDX Password

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 Password

Confirm the password by retyping it here.

SSL

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.

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

Total VPX instances

Indicates the total number of VPX instances on the monitored NetScaler SDX appliance.

Number

Use the detailed diagnosis of this measure to know the names of the VMs and VPX instances on the target SDX appliance.

VPX instances with UP state

Indicates the count of VPX instances that are up and running currently.

Number

Use the detailed diagnosis of this measure to know the names of the VPX instances that are in the UP state and the names of VMs hosting the UP instances.

VPX instances with Down state

Indicates the number of VPX instances that are not running presently.

Number

Use the detailed diagnosis of this measure to know which VPX instances are down and which VMs host them.

Running VMs

Indicates the number of VMs that are up and running currently.

Number

Use the detailed diagnosis of this measure to know the name and IP address of the running VMs and the names of the VPX instances they host.

Halted VMs

Indicates the count of halted VMs.

Number

Use the detailed diagnosis of this measure to know which VMs on the target SDX appliance are not running currently and which are the VPX instances they host.

With the help of the detailed diagnosis of the Total VPX instances measure, you can instantly identify the VPX instances that have been configured on each of the VMs on the SDX appliance.
