DevTest Test Event Metrics

Test Event Metrics provide metrics in regard to DevTest events. These metrics include both counters and gauges.

Event metrics let you filter events of a specific type by including a regular expression to match the short description field of the event.

The Test Event Metrics category has eight submetrics:

• Coordinator server started
• Coordinator server ended
• Coordinator started
• Coordinator ended
• Test started
• Test ended
• Instance started
• Instance ended

To add test event metrics:

In addition to selecting the metric, you can specify:

• Key Expression Match: Enter an expression to say to sample the chosen event only if it has this expression in its short description field. If you leave this field blank, or enter *, then every event of this type is reported.
• Metric is a Counter: If this box is selected, the value counts over time are recorded. If the box is cleared, the absolute value is recorded (metric is functioning as a gauge).

Test Event metrics are meant to track the presence of specific events in the workflow engine. When the Counter check box is selected, the metric collector tracks the number of times that the chosen event was observed. The count increases as the test runs; however, the graphs in DevTest Workstation and the reporting console shows the value that was collected during the sampling period. This is the default option for Test Event Metrics.

If the Counter check box is not selected, the metric collector attempts to parse the long description of the event as a number. During the sampling period the collector keeps a running total of these parsed values. When the metric is reported it is a simple average of the parsed numbers. The running total is reset for each sampling period. If there is not a number value that is contained in the long description of the event, the metric value is 0.

The default sampling period is 1 second and can be modified in the staging document.
