+The APM app allows you to define **rules** to detect complex conditions within your APM data
+and trigger built-in **actions** when those conditions are met.
 
-The APM app integrates with Kibana's {kibana-ref}/alerting-getting-started.html[alerting and actions] feature.
-It provides a set of built-in **actions** and APM specific threshold **alerts** for you to use
-and enables central management of all alerts from <<management,Kibana Management>>.
+The following **rules** are supported:
+
+* Latency anomaly rule:
+Alert when latency of a service is abnormal
+* Transaction error rate threshold rule:
+Alert when the service's transaction error rate is above the defined threshold
+* Error count threshold rule:
+Alert when the number of errors in a service exceeds a defined threshold

-The APM app supports four different types of alerts:
-
-* Transaction duration anomaly:
-alerts when the service's transaction duration reaches a certain anomaly score
-* Transaction duration threshold:
-alerts when the service's transaction duration exceeds a given time limit over a given time frame
-* Transaction error rate threshold:
-alerts when the service's transaction error rate is above the selected rate over a given time frame
-* Error count threshold:
-alerts when service exceeds a selected number of errors over a given time frame
+For a complete walkthrough of the **Create rule** flyout panel, including detailed information on each configurable property,
+see Kibana's <<create-edit-rules,create and edit rules>>.
