• Dynatrace Portal - Backbone
  • Dynatrace Classic Portal

The Health Monitor tool lets Synthetic Classic customers measure and evaluate site performance based on user-defined thresholds. These thresholds can be defined when editing the Backbone test in the Admin tab of the Dynatrace Classic Portal.

In Backbone tests, the Health Monitor settings let you measure and evaluate site performance based on user-defined thresholds.

You define these thresholds in the Advanced Settings of the Backbone test.

The Number of Tests setting defines the number of historic test results that will be averaged for all of the test's nodes to calculate a baseline for the test. For example, if you enter 5 in this field, the Health Monitor averages the last five test runs on the test's nodes and use this average to compare new test runs to the baseline.

To define the Health Monitor for a Backbone test:

  1. Open the Edit a TestType Test window for the test.
    For details, see Editing Tests in the documentation.
  2. Select the Advanced Settings tab.
  3. In the SLA Management: Health Monitor section, enter values for the Health Monitor settings.
    • Number of Tests – Described above.
    • Break Time – The maximum acceptable response time, in seconds, defined by the SLA.
    • Over Threshold – The acceptable percentage of tests exceeding the SLA response time.
    • Caution Time – The response time, in seconds, that does not exceed the SLA but is a warning that performance is degrading.
    • At Risk – The percentage of tests exceeing the Caution Time.
  4. Click Update and Finish.
