+# AppDynamics integration for Grafana OnCall
+
+The AppDynamics integration for Grafana OnCall handles health rule violation events sent from AppDynamics actions.
+The integration provides grouping and auto-resolve logic via customizable alert templates.
+
+## Configure AppDynamics integration for Grafana OnCall
+
+You must have an Admin role to create integrations in Grafana OnCall.
+
+1. In the **Integrations** tab, click **+ New integration to receive alerts**.
+2. Select **AppDynamics** from the list of available integrations.
+3. Follow the instructions in the **How to connect** window to get your unique integration URL and review next steps.
+
+## Grouping and auto-resolve
+
+Grafana OnCall provides grouping and auto-resolve logic for the AppDynamics integration:
+
+- Alerts created from health rule violation events are grouped by application and node name
+- Alert groups are auto-resolved when the health rule violation is ended or canceled
+
+To customize this behaviour, consider modifying alert templates in integration settings.

+    After setting up a template, create a new action in AppDynamics and select the template you created earlier.
+    Now you can configure policies to trigger the action when certain events occur in AppDynamics.
+    <br>
+    When configuring a policy, select the following events to trigger the action:
+    <ul>
+        <li><code>Health Rule Violation Started - Warning</code></li>
+    <li><code>Health Rule Violation Started - Critical</code></li>
+    <li><code>Health Rule Violation Continues - Warning</code></li>
+    <li><code>Health Rule Violation Continues - Critical</code></li>
+    <li><code>Health Rule Violation Upgraded - Warning to Critical</code></li>
+    <li><code>Health Rule Violation Downgraded - Critical to Warning</code></li>
+    <li><code>Health Rule Violation Ended - Warning</code></li>
+    <li><code>Health Rule Violation Ended - Critical</code></li>
+    <li><code>Health Rule Violation Canceled - Warning</code></li>
+    <li><code>Health Rule Violation Canceled - Critical</code></li>
+    </ul>
+</p>
+
+<p>
+    After setting up the connection, you can test it by sending a test request from the AppDynamics UI.
