Pure Host Capacity Test

This test auto-discovers the hosts connected to the target FlashArray, and for each host, this test reports the total capacity, the space availability, the size of the volume and the amount of space occupied by the snapshots.

Target of the test : Pure Storage FlashArray

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each host connected to the target FlashArray being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The IP address of the host for which this test is to be configured.


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

API Token

The eG agent collects the required metrics from the Pure Storage Flash Array by executing API commands using Pure Storage REST API on the FlashArray and pulls out critical metrics. In order to collect metrics, the eG agent should be provided with a valid API token. To know how to determine the API token, refer to Pre-requisites for Monitoring the Pure Storage FlashArray. Specify the determined API token in the API Token text box.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 2:1. 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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total capacity

Indicates the total capacity allocated to this host.


The detailed diagnosis of this measure reveals the details on data reductions.

Used capacity

Indicates the amount of space utilized by this host.


Free capacity

Indicates amount of space that is available for use by this host.


Capacity used

Indicates the percentage of space utilized by this host.


Capacity free

Indicates the percentage of space that is available for use by this host.



Indicates the size of the volume utilized by this host.


Ideally, the value of these measures are desired to be low.


Indicates the space utilized for storing the snapshots of the volume to which this host has been connected with.
