Fujitsu CM Channel Adapter Port Test

This test monitors the workload of each channel adapter port and helps administrators identify the port through which maximum read/write IOPS is done.

Target of the test : Fujitsu Storage AF/DX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each channel adapter port in a Fujitsu Storage AF/DX that is currently launched.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The nick name of the Fujitsu Storage AF/DX component for which this test is to be configured.

Port

Refers to the port at which the specified host listens to. By default, this is NULL.

Timeout

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

Use SUDO

To run this test and report metrics, the eG agent install user should have permissions to run the rndc stats command and read from the statistics-file. If the eG agent install user possesses these privileges, then set the Use SUDO flag to No. If the eG agent install user does not have the required permissions, then do the following:

  • Edit the sudoers file on the target host and append an entry of the following format to it:

    <eG_agent_install_user>; ALL=(ALL) NOPASSWD:<Command>;

    For instance, if the eG agent install user is eguser, then the entry in the sudoers file should be:

    eguser ALL=(ALL) NOPASSWD: rndc stats

  • Then, save the file.
  • Finally, set the Use SUDO parameter to Yes.

High Security

This flag is applicable only when the target Linux host is monitored in the agentless manner. In highly secure environments, eG Enterprise could not perform agentless monitoring the Fujitsu Storage running on a Linux host using SSH. To enable monitoring of the Fujitsu Storage in such environments, set the HIGH SECURITY flag to Yes. It indicates that eG Enterprise will connect to the target Fujitsu Storage in a more secure way and collect performance metrics. By default, this flag is set to No.
Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Read IOPS

Indicates the number of read operations performed on this channel adapter port per second.

Operations/sec

Compare the values of these measures across channel adapter ports to know what is contributing to the abnormal I/O activity levels - read operations? or write operations?

 

Write IOPS

Indicates the number of write operations performed on this channel adapter port per second.

Operations/sec

Read throughput

Indicates the rate at which this channel adapter port processes read requests.

MB/Sec

 

Write throughput

Indicates the rate at which this channel adapter port processes write requests.
