You can use the default health rules provided by AppDynamics as-is or modify them to map to your requirements or define a custom health rule.
You configure health rule details in the Overview panel.
The Always option is pre-selected in the When is the rule enabled? drop-down list. If the health rule is enabled only at certain times, select other predefined schedules from the When is the rule enabled? drop-down list.
To define a custom health rule schedule or modify the predefined time intervals, click Manage Health Rule Schedules. See Create and Manage Health Rule Schedules.
Click the drop-down list Use data from last <> min(s) and select a number between 1 and 360 minutes. The value you specify is the latest time interval during which data is collected to determine if there is a health rule violation. This value applies to both critical and warning criteria. See Health Rule Evaluation Time Frame.
If you have defined a persistence threshold for the health rule condition, ensure that you define an evaluation time frame of 30 mins or less.
In the Wait Time after Violation field, enter the number of minutes to wait before re-evaluating the rule for the same affected entity in which the violation occurred. See Health Rule Wait Time After Violation.
Save your configuration.
