Define service level agreements

This topic describes how to define service level agreements (SLAs).

Flow

You can define SLAs in Controller or Analysis. The SLAs can measure scenario goals over time intervals, or over a whole scenario run. For details, see Service level agreements overview.

Note:

If you are defining an SLA for Transaction Response Time, your scenario must include a script that contains at least one transaction.
For a use-case scenario related to this task, see Define service level agreements - use-case scenario.

To define SLAs:

Open the wizard in one of the following ways:
- Analysis:Tools menu > Configure SLA Rules > Service Level Agreement window > New button
- Controller:Design tab > Service Level Agreement window > New button
For user interface details, see the Service Level Agreement wizard.
Run through the SLA wizard process.
Define a tracking period - optional

For measurements whose SLA statuses are determined over time intervals, you can define the frequency of the time intervals also known as the tracking period. For details, see Tracking period.

You define the Tracking period in the Advanced Options area. For details, see the Advanced Options dialog box (SLA).
View results

When analyzing your scenario run, Analysis compares the data collected from the scenario run against the SLA settings, and determines SLA statuses and APDEX scores. These are displayed in the Statistics section of the default Summary Report.

You can edit the SLA settings after the scenario run—the Statistics section is updated to reflect the new settings.

This pane lists all the service level agreements (SLAs) defined for the scenario.

To access, select:
