OS Details - OpenStack Test

This test collects various metrics pertaining to the CPU, disk, and memory usage of every OpenStack hypervisor supported by the target OpenStack Controller. Using the metrics reported by this test, administrators can optimize the resource utilization of the hypervisors so as to ensure seamless operations on the hypervisors.

Target of the test : An OpenStack Controller

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each OpenStack hypervisor connected to the target OpenStack Controller.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed.
Host	The host for which the test is to be configured.
Port	The port number at which the specified Host listens to.
Project Name	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 this 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.
Domain Name and Domain ID	Specify the name and ID of the domain to which the specified project belongs to against the Domain Name and Domain ID parameters. To know how to find out the domain name and domain ID from the OpenStack console, refer to Obtaining Project Name and Domain Details from OpenStack Console.
User Name, Password and Confirm Password	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 User Name and Password text boxes. Then, confirm the password by retyping it in the Confirm Password text box.
Identity Version	Specify the version of the Identity service API that is being used in the OpenStack environment. By default, this parameter is configured with the latest version of the API i.e. v3.
SSL	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.
Detailed Diagnosis	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.
