Test Suite Editor - Metrics Tab

The Metrics tab of the Test Suite Editor is where you select the test metrics to record. This tab is also where you set the sampling specifications for the collection of the metrics.

You can also set an email alert on any metric that you have selected.

The Metrics tab is divided into two sections.

The top panel shows the default metrics that are added to the suite. You can add more metrics by clicking Add on the toolbar.

In the bottom panel, two slider bars enable you to set sampling parameters:

• Sample rate: This value specifies how often to take a sample; that is, record the value of a metric. This parameter is specified as a time period, and is the reciprocal of the sampling rate.
• Samples per interval: This value specifies how many samples are used to create an interval for calculating summary values for the metric.

Taking sample values every minute (Sample Rate Per Interval=1 minute), and averaging every 60 samples (Samples Per Interval=60), produces a metric value every minute, and a summary value (average) every hour.

For example, the default is a 1-second Sample Rate, and 10 samples per interval (making an interval 10 seconds).

The metric values are stored in XML files or database tables for including in reports (see Reports).

Adding Metrics

The following metrics categories are available:

• DevTest Whole Test Metrics
• DevTest Test Event Metrics
• JMX Metrics
• SNMP Metrics
• TIBCO Hawk Metrics
• Windows Perfmon Metrics
• UNIX Metrics Via SSH

To add metrics:

1. Click Add on the toolbar.

   The Add Metric dialog appears.

2. Select the target metric and click OK.
3. To configure metrics from the other categories, repeat the procedure.

For full descriptions of all the metrics, in all categories, and details on how to configure them for including in your reports, see Generating Metrics.

Setting Email Alerts

Follow these steps:

1. Click the Set Alert button corresponding to the metric.

   The Edit Alert dialog appears.

2. You can set the acceptable limits for the metric (low and high value), and the details to be sent in an email. You must provide the name of your email server, and a list of email addresses.
3. Add and delete email addresses by using the Add and Delete icons at the bottom of the window.
4. When finished, click Close.
