Fujitsu RAID Groups Test

This test monitors the status and capacity of each RAID group. This test helps the administrators to easily identify the RAID group that is overly utilized.

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 RAID group 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.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

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.

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current state of each RAID groups. The graph of this measure however is represented using the numeric equivalents only.

Total capacity

Indicates the total capacity of this RAID group.

GB

 

Free space

Indicates the amount of unused space in this RAID group.

GB

A high value is generally desired for this measure. A very low value or a consistent dip in this value could indicate a space crunch in the RAID group.

Used space

Indicates the total amount of space used by all disks in this RAID group.

GB

Ideally, the value of this measure should be low. If this value grows close to that of the Total capacity measure, then you may want to consider adding more disks to the storage system, or free space in the disks by deleting unnecessary data.

Raid group usage

Indicates the percentage of space used in this RAID group.

Percent

Ideally, the value of this measure should be low.

Disk count

Indicates the total number of disks available in this RAID group.

Number

Use the detailed diagnosis of this measure to find out the disk name, status, usage, and the data access failed.

Volume count

Indicates the total number of volumes available in this RAID group.

Number

Use the detailed diagnosis of this measure to find out the volume name, status, type, and size on the RAID.
