Configuration of OSHvHypervisorTest

Using this test, administrators can receive micro-level view of the composition of the target OpenStack KVM hypervisor. This test reveals the current status of the target hypervisor and the total number of vCPUs and also precisely reports the count of vCPUs the are free to be used on the hypervisor. This test also tracks the memory and local disk utilization on the hypervisor. This enables administrators to rapidly detect potential memory/local storage shortages at the earliest and initiate the appropriate remedial measures. Furthermore, this test reveals the count of cells, sockets and threads utilized on the hypervisor. Using these metrics, administrators can easily take decisions on scaling up the environment without increasing workload and latency. This test also reveals the current workload on the hypervisor, which helps administrators understand whether resources are being utilized adequately or over-utilized.

The default parameters associated with this test are as follows:

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

  • In the HOST text box, specify the host for which the test is to be configured.

  • In the PORT text box, specify the port number at which the specified Host listens to.

  • To enable this test to access the target hypervisor and pull out the performance metrics, you should specify the name of the project that is mapped to the target hypervisor in the PROJECT NAME text box. To know how to find out the project name from the OpenStack console, refer to Obtaining Project Name and Domain Details from OpenStack Console.

  • To enable this test to pull out the performance metrics, you should configure the test with credentials of a user who is assigned with 'reader' role to access the above-mentioned project. Specify the credentials of such a user in the USERNAME and PASSWORD text boxes, and confirm the password by retyping it in the CONFIRM PASSWORD text box.

  • Specify the version of the Identity service API that is being used in the OpenStack environment. By default, the IDENTITY VERSION parameter is configured with the latest version of the API i.e. v3.

  • By default, the target controller is not SSL-enabled. This indicates that by default, the eG agent communicates with the target controller using HTTP. Accordingly, the SSL flag is set to No by default. If you configure the target controller to use SSL, then make sure that the SSL flag is set to Yes, so that the eG agent communicates with the target controller using HTTPS.

  • 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 button will appear in this page. Clicking on this button 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.
