Retest period

The service retest parameters are generic optional monitor parameters. The parameters define the period after which a failed service level is generated. Failed service levels affect your service agreement with the client.

Internet services are sometimes momentarily interrupted due to transient failures. If a service fails but then recovers during the retest period the monitor does not record a service level failure. This allows you to ignore transient errors.

For example, you might have an HTTP monitor that is configured to perform a test on a web page every ten minutes. In addition, you can configure the monitor so that if the web page fails, the monitor tests the web page five more times with five second intervals between the tests. If the web page fails all retests, the monitor records a failure for the service.

Monitors indicate the number of interim failures during the retest period in the $consecutiveFailures field of the test results data.
