Disk Space - OS Test

How often should the test be executed.

The nick name of the Linux Systems Group component for which this test is to be configured.

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

To obtain the 'inside view' of performance of the systems - i.e., to measure the internal performance of the systems - this test uses a light-weight eG VM Agent software deployed on each of the systems. Accordingly, this parameter is by default set to eG VM Agent.

This flag is set to No by default. This implies that the Linux systems in environments will always be identified using the system name. In other words, this test will, by default, report measures for every systemname. On the other hand, if you want this test to report the measures for every user on a system, then set this flag to Yes. In such a case, this test will report the measures for every username_on_systemname.

By default, this flag is set to Yes, then the 'inside view' tests will report measures for even those Linux systems that do not have any users logged in currently. The systems will be identified by their name and not by the username_on_systemname. On the other hand, if this flag is set to No, then this test will not report measures for those systems to which no users are logged in currently.

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

Optionally, you can configure this test to automatically initiate a disk cleanup action, if any disk partition on any VM is found to be running out of free disk space. This way, you can enable the test to pre-empt a potential space crunch and ensure the peak performance and uninterrupted functioning of applications running on the VMs. To enable the test to take such corrective action automatically, set this flag to Yes (default: No).

This parameter applies only if the 'Automated Action Enabled' flag is set to 'Yes'.

By default, this parameter is set to 95%. This means that, by default, this test will automatically cleanup unwanted files (eg., temp files) on any disk for which the Percent usage measure reports the value 95% or higher. This way, the test makes sure that there is always adequate free space on disks for the use of physical applications. If you want, you can change the value of this parameter to suit the needs of your environment.

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.

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

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.
