Image Details - OpenStack Test

OpenStack Controller runs Image service that enables users to discover, register, and retrieve virtual machine images. The Image service offers a REST API that enables you to query virtual machine image metadata and retrieve an actual image. The virtual machine images made available through the Image service can be stored in a variety of locations, from simple file systems to object-storage systems like OpenStack Object Storage. The virtual machine images retrieved by the Image services should be active and ready to be booted to create virtual machines. If the image is not fully stored or is unable to boot due to lack of required memory and disk space, then, administrators will not be able to create the virtual machines as planned or will experience delay. This is why, administrators need to continuously monitor status of each image retrieved by the Image service and disk/memory requirements to boot the image. This can be achieved using the Image Details - OpenStack test.

This test continuously monitors the images and promptly reports the current status of each image. This measure enables administrators to instantly find out whether the image saving process is success or interrupted by any error. In addition, this test also reveals the current size of the image and the minimum amount of memory and disk space required to boot the image.

Target of the test : An OpenStack Controller

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each image made available through the Image service that is being run by 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.

Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Image status

Indicates the current status of this image.

The values this measure reports and their numeric equivalents are provided in the table below:

Measure Value	Numeric Value
Active	100
Saving	50
Saving	25
Deleted	10
Error	0

Note:

Typically, this measure reports one of the Measure Values listed in the table above. In the graph of this measure however, the status of each image is indicated by its corresponding numeric equivalent only.

The detailed diagnosis of this measure reveals the image name, image ID, name of a user who owns the image, format in which the image was stored on the disk, container format, the date at which the image was created.

Minimum memory

Indicates minimum amount of RAM required to boot this image.

Minimum disk size

Indicates the minimum disk space required to boot this image.

Saving progress

Indicates the progress percentage of the saving process that was initiated when this image was being saved.

Percent

Image size

Indicates the current size of this image.
