Configuration of NutClusComputeTest

This test auto-discovers the clusters managed by the monitored Nutanix Prism, and reports the following for each cluster:

  • The number and names of VMs and hypervisors managed by each cluster;

  • The total compute and storage capacity of every cluster;

  • How every cluster is using the available capacity;

  • How every cluster is using the available capacity;

  • The I/O load on each cluster;

  • How each cluster is handling the I/O load;

In the process, the test pinpoints those clusters that many not have the storage and processing power to handle their current and anticipated load, and are hence candidates for expansion.

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 the host name of the server for which the test is to be configured in the HOST text box.

  • Specify the port on which the HOST is listening in the PORT text box. By default, this is NULL.

  • To connect to the Nutanix Prism and collect metrics from it, the eG agent should be configured with the credentials of a Cluster administrator or a User administrator. This is why, you need to specify the name and password of such a user in the NUTANIX PRISM USER and NUTANIX PRISM PASSWORD text boxes, respectively. However, some high security Nutanix environments may prefer not to expose the credentials of a Cluster administrator or a User administrator. In such environments, the eG agent can be configured with the credentials of a Prism user with the Viewer role. To know the steps for creating such a user, click here.

  • Confirm the password by retyping it in the CONFIRM PASSWORD text box.

  • By default, the Nutanix Prism server is SSL-enabled. Accordingly, the SSL flag is set to Yes, by default. This indicates that the eG agent will communicate with the Prism server via HTTPS by default.

  • By default, the Nutanix Prism server listens on port 9440, which appears in the WEBPORT parameter. This implies that while monitoring a Nutanix Acropolis server via the Prism server, the eG agent connects to port 9440.

  • The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. For a Nutanix Acropolis Prism server, this is set to 1:1 by default. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem.

  • To make diagnosis more efficient and accurate, the eG Enterprise suite 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.
