Node CPU Utilization Test

This test auto-discovers the nodes on the target storage system, and monitors the CPU utilization of each node. This way, the test points administrators to figure out how CPU hungry each node is.

Target of the test : An EMC Isilon Storage System

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each node on the target storage system being monitored.

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 this test is to be configured.

Port

The port at which the host listens. By default, this will be NULL.

Timeout

Specify the time duration (in seconds) beyond which this test should time out in the Timeout text box. The default is 10 seconds.

Use SUDO

By default, this parameter is set to No. This indicates that, by default, the eG agent will not require any special permissions to execute the commands. However, in some highly secure environments, this command cannot be executed directly as the eG agent install user is different from the root user who has the privileges to run all commands on the target storage system. In such cases, create a sudo user using the steps discussed in the Pre-requisites for Monitoring the EMC Isilon Storage System. Credentials of such a user should be specified in the Username and Password text boxes in the COMPONENTS page.

Set the Use Sudo parameter to Yes. This will enable the eG agent install user to execute the commands.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

CPU usage

Indicates the percentage of CPU utilized by this node.

Percent

Compare the value of this measure across the nodes to identify the node which consumes the maximum CPU.
