Disk Space - OS Test

This test monitors the disk space usage of Cloud PCs to help administrators identify if the PCs are provided with sufficient disk space. The test monitors the disk partitions used by each Cloud PC and reports the total, used, and free disk space on each disk partition, enabling proactive management of low disk space conditions. By tracking usage trends, the test helps prevent performance degradation and system errors due to insufficient disk space.

Target of the test : A Windows 365 PCs Group

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every combination of CloudPC:disk_partition

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The nick name of the Windows 365 Cloud PCs Group 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.

Report Powered OS

If this flag is set to Yes (which is the default setting), then the 'inside view' tests will report measures for even those Cloud PCs that do not have any users logged in currently. Such PCs will be identified by their name and not by the username_on_CloudPCName. On the other hand, if this flag is set to No, then this test will not report measures for those Cloud PCs to which no users are logged in currently.  

Report By User

This flag is set to Yes by default. The value of this flag cannot be changed. This implies that the Cloud PCs in environments will always be identified using the login name of the user. In other words, this test will, by default, report measures for every username_on_CloudPCName.

DD Enable Utilization Percent

By default, this parameter is set to 90%. This means that, by default, this test will automatically enable detailed diagnosis for the Percent usage measure when the Percent usage measure reports the value 90% or higher. However, you can override the value of this parameter to suit the needs of your environment.

Exclude

By default, this test excludes a few disk partitions from monitoring. These include disks storing snapshots, user's runtime information, boot strap files, and container daemons. If you want, you can alter this default list by appending more partitions to it separated by commas, or by removing a few existing partitions from it. Wild card patterns are also supported. For example, you specification can be: */var/lib/containers/*,*/snap/*,*/run/user/*,*/run/lock/*,*/media/*,*/mnt/boot/*,*/run/containerd/*,*/var/lib/docker/*

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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total capacity

Indicates the total capacity of a disk partition.

MB

 

Used space

Indicates the amount of space used in a disk partition.

MB

 

Free space

Indicates the current free space available for each disk partition of a system.

MB

 

Percent usage

Indicates the percentage of space usage on each disk partition of a system.

Percent

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

The detailed diagnosis, if enabled, reveals the directories and files consuming the most disk space on the Cloud PC, providing insights into their size and overall storage utilization.
