Disk Usage Test

This test monitors the space usage of every disk partition on 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 disk partition 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

Total capacity

Indicates the total capacity of this disk partition.

MB

 

Used space

Indicates the amount of space in this disk partition that is currently in use.

MB

Ideally, this value should be low.

Free space

Indicates the amount of space in this disk partition that is currently unused/free.

MB

Ideally, this value should be high.

Percent usage

Indicates the percentage of space usage on this disk partition.

Percent

A value close to 100% may indicate a potential problem situation where applications executing on this NetScaler device may not be able to write data to the disk partition(s) with very high usage.
