Viewing Machine learning analyzers

HCL DevOps Test Hub (Test Hub) analyzes certain types of tests that are run in a team space by using its Machine learning (ML) capabilities. You can then view the findings of the analysis as recommendations about the tests on the Analyzers page in the team space. These recommendations provide an insight into the tests and help you troubleshoot the problems in the tests.

Before you begin

You must have completed the following tasks:

Ensured that you are assigned a role as a Viewer, Tester, or Project Owner in the project.
Ran the Performance Test or Schedule that matches the minimum requirements for ML analysis in Test Hub. See Configuring a run of a Compound Test that contains performance tests or Configuring a run of a Rate Schedule or VU Schedule.

About this task

If the Performance Tests or Schedules that are run from projects in a team space match the requirements and criteria for ML analysis, Test Hub analyzes the tests during their runs.

Procedure

Click Infrastructure > Analyzers in the navigation pane.

The Analyzers page is displayed.

You can view the parameters that are supported for ML analysis listed in a tabular format. The information displayed is as follows:

Column header

Description

Status

Displays the status of the parameter analysis as active or inactive in the team space. The default value of the analysis is set as active or enabled.

Name

Displays the name of the parameters that are supported for ML analysis, which is as follows:

Response Time Lock-Step Pattern
Response Time Standard Deviation Pattern
Throughput Drop Pattern

Version

Displays the version of the ML analyzer.

Last Run

Displays the date when the tests were run for the analysis.

Unreviewed insights

Displays the number of insights into the specific parameter analyzed from different tests that are not reviewed by the project members.

Actions

Displays the following icons for the actions that you can perform on each parameter analyzed:


Icon	Description
	Displays the Edit Analyzer dialog when clicked. You can modify the analyzer settings for subsequent analysis.
	Displays a dialog that contains the list of the reactions marked by different members on insights into the specific parameter when clicked. The agreement or disagreement reactions by members with the date and time of marking them are listed in chronological order in the dialog. You can view the insight on the Insights page in the project when you click .

Click the Expand icon of the parameter to view the details.

The details of the parameter are displayed.
Read the details about the analysis and recommendations for troubleshooting or resolving the problems detected in the analysis.

See the information in the related links to understand how to interpret the analysis of the parameters.

Results

You viewed the details of the parameters that are analyzed by Test Hub in tests that were run in the team space.
