Configuration of NutAhvComputeTest

This test reports how the physical CPU and memory resources are used by an AHV host, and alerts you to erratic usage patterns. In the event of abnormal resource usage, the test also points you to the resource-starved VMs on the host, and thus reveals what is causing the usage anomaly - the VMs? or resource-intensive processing at the host-level?

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.

  • If the eG manager had discovered the target Nutanix Acropolis server by connecting to the Nutanix Prism, then the IP address of the Nutanix Prism server used for discovering this Nutanix Acropolis server would be automatically displayed against the PRISM IP parameter; similarly, the PRISM USER and PRISM PASSWORD text boxes will be automatically populated with the Prism user credentials, using which Nutanix Acropolis discovery was performed.

    If this Nutanix Acropolis server has not been discovered using the Nutanix Prism, but you still want to monitor the Nutanix Acropolis server via the Prism, then select the IP address of the Prism server that you wish to use for monitoring the Nutanix Acropolis server from the PRISM IP list. By default, this list is populated with the IP address of all Nutanix Prism hosts that were added to the eG Enterprise system at the time of discovery. Upon selection, the PRISM USER and PRISM PASSWORD that were pre-configured for that Nutanix Prism will be automatically displayed against the respective text boxes.

    On the other hand, if the IP address of the Prism server of interest to you is not available in the list, then, you can add the details of the Prism server on-the-fly, by selecting the Other option from the PRISM IP list. This will invoke the MANAGER DISCOVERY - VIRTUAL PLATFORM SETTINGS page. Refer to the Monitoring Nutanix Acropolis document for details on how to use this page.

  • 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 will be automatically populated against 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. 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 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.
