NetScaler CPU Usage Test

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

Target of the test : An ADC VPX/MPX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each processor supported by the ADC 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 ADC device, the eG agent should be configured with the credentials of a user with read-only privileges to the target ADC device. Specify the credentials of such a user in the NetScaler Username and NetScaler Password text boxes.
Confirm Password	Confirm the password by retyping it here.
SSL	The eG agent collects performance metrics by invoking NITRO (ADC Interface Through Restful interfaces and Objects) APIs on the target ADC 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 ADC 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 ADC device as a whole. A value close to 100% indicates a CPU bottleneck on the ADC device.
Management CPU usage	Indicates the current management CPU usage of the ADC 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 ADC 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 ADC device.	Number	This measure is available only for the 'Summary' descriptor.
