VM Status - OpenStack Test
This test continuously the target OpenStack KVM hypervisor and reports the count of virtual machines (VMs) that are in different states. This test enables administrators to instantly determine how many VMs are currently running on the target hypervisor and how many VMs are deleted/stopped/paused/suspended. In addition, the test also reveals the count of VMs that encountered unrecoverable errors. Using the metrics reported by this test, administrators can promptly identify the reason for inaccessibility of the VMs whenever users complain of the same.
Target of the test : An OpenStack KVM
Agent deploying the test : A remote agent
Outputs of the test : One set of results for the target hypervisor.
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:
