NetScaler CPU Usage Test

This test reports how well the CPU resources are utilized by the NetScaler device and also reports the number of CPU cores available in the NetScaler device.

Target of the test : A NetScaler VPX/MPX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each processor supported by the NetScaler device.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which the test is being configured.

NetScaler Username and NetScaler Password

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

Confirm Password

Confirm the NetScaler 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 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 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.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

CPU usage

Indicates the percentage of CPU resources used by this processor.

Percent

For the 'Summary' descriptor, this value indicates the overall CPU usage of the NetScaler device as a whole. A value close to 100% indicates a CPU bottleneck on the NetScaler device.

Management CPU usage

Indicates the current management CPU usage of the NetScaler device.

Percent

This measure is available only for the 'Summary' descriptor. Ideally, the value of this measure should be low.

Packet CPU usage

Indicates the current packet CPU usage of the NetScaler device.

Percent

This measure is available only for the 'Summary' descriptor. Ideally, the value of this measure should be low.

CPU cores

Indicates the number of CPU cores currently supported by the NetScaler device.

Number

This measure is available only for the 'Summary' descriptor.
