Default Parameters for HvVMSnapshotTest
This test reports the count of large and aged checkpoints per VM, and reveals the names of these checkpoints, so that administrators can decide whether/not these checkpoints can be removed to make more storage space available for the VM.
This page depicts the default parameters that need to be configured for the HvVMSnapshotTest.
By default, the value of the AGE LIMIT IN DAYS parameter is set to 15 days. This implies that the test will report all those checkpoints that are more than 15 days old as Aged checkpoints. If required, you can change the AGE LIMIT.
By default, the value of the SIZE LIMIT IN MB parameter is set to 10000 MB. This implies that the test will report all those checkpoints that have a size more than 10000 MB as Large checkpoints. If required, you can change this limit.
By default, this test connects to each virtual guest remotely and attempts to collect “inside view” metrics. Accordingly, the INSIDE VIEW USING flag is set to Remote connection to VM (Windows) by default. To obtain a remote connection, the test must be configured with the privileges of an administrative user to the domain within which the guests reside. The first step towards this is to specify the DOMAIN within which the virtual guests reside. The ADMIN USER and ADMIN PASSWORD will change according to the DOMAIN specification. Discussed below are the different values that the DOMAIN parameter can take, and how they impact the ADMIN USER and ADMIN PASSWORD specifications:
- If the VMs belong to a single domain: If the guests belong to a specific domain, then specify the name of that domain against the DOMAIN parameter. In this case, any administrative user in that domain will have remote access to all the virtual guests. Therefore, an administrator account in the given domain can be provided in the ADMIN USER field and the corresponding password in the ADMIN PASSWORD field. Confirm the password by retyping it in the CONFIRM PASSWORD text box.
- If the VMs belong to different domains: In this case, you might want to provide multiple domain names. If this is done, then, to access the guests in every configured domain, the test should be configured with the required user privileges; this implies that along with multiple DOMAIN names, multiple ADMIN USER names and ADMIN PASSWORDS would also have to be provided. To help administrators provide these user details quickly and easily, the eG administrative interface embeds a special configuration page. To access this page, simply click on the Click here hyperlink that appears just above the parameters of this test in the test configuration page. To know how to use the special page, refer to Monitoring Microsoft Hyper - V document.
- If the INSIDE VIEW USING flag is set to ‘eG VM Agent (Windows)’: On the other hand, if the INSIDE VIEW USING flag is set to eG VM Agent (Windows), then it implies that the inside view can be obtained without domain administrator privileges. Therefore, set the DOMAIN, ADMIN USER, and ADMIN PASSWORD parameters to none.
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.
When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
