    This page provides instructions on creating health rules in AppDynamics.

    You can use the default health rules provided by AppDynamic, modify them to map to your requirements, or define a custom health rule.

    Access the Health Rule Wizard

    1. Click Alert & Respond in the menu bar.
    2. Click Health Rules either in the right panel or the left navigation pane.
    3. Select the context for the health rule from the pulldown menu.
    4. Do one of the following:
      • To create a new health rule, click the + icon.
      • To edit an existing health rule, select the health rule and click the Edit (pencil) icon.
      • To remove an existing health rule, select the health rule and click the Delete icon.

    Configure Heath Rule Details

    You configure health rule details in the Overview panel.

    1. Enter a name. If a name already exists, you can change it.
    2. Check Enabled to enable the rule, clear the checkbox to disable it.
    3. 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.

    4. Click the drop-down list Use data from last <> min(s) and select a number between 1 and 120 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.

    5.  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.

    After you configure the Health Rule details in the Overview panel, proceed with the following steps.

    1. Configure the entities affected for the health rule, see Configure Affected Entities.
    2. Define the evaluation criteria for the health rule, see Configure Health Rule Evaluation Criteria.
    3. Save your configuration.
