Configuration of VmgDiskSpaceTest

This test monitors the space usage of every disk partition on a physical desktop.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the nick name of the target component for which this test is to be configured in the HOST text box.

• Indicate the port at which the host listens to in the PORT text box. By default, this is NULL.

• To obtain the ‘inside view’ of performance of the desktops - i.e., to measure the internal performance of the physical desktops - this test uses a light-weight eG VM Agent software deployed on each of the desktops. Accordingly, INSIDE VIEW USING parameter is by default set to eG VM Agent.

• The REPORT POWERED OS is relevant only for those tests that are mapped to the Physical Desktops Details layer. If this flag is set to Yes (which is the default setting), then the 'inside view' tests will report measures for even those physical desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_physicalmachinename. On the other hand, if this flag is set to No, then this test will not report measures for those physical desktops to which no users are logged in currently.

• REPORT BY USER flag is set to Yes by default. This implies that the physical machines 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_physicalmachinename.

• IS CLOUD VMs flag is set to Yes by default. This implies that the physical machines 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_physicalmachinename.

• 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 AUTOMATED ACTION ENABLED flag to Yes (default: No).

• Drive Utilization Limit parameter applies only if the 'Automated Action Enabled' flag is set to 'Yes'. By default, DRIVE UTILIZATION LIMIT 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, EXCLUDE 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.

• The 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.

• 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.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
