Triggers
You can populate the data in a report based on certain conditions. When those conditions are met, the trigger is executed. Based on your requirements, you can modify threshold values by using REST APIs.
http://<host>:<appnode_port>/monitor as a base URL for all the REST APIs provided where, http://localhost:8090/monitor is the default endpoint. Here, 8090 is the AppNode port.The following triggers are available:
High CPU Trigger

| Threshold | highMemoryThresholdPercent: 80 highMemoryDurationMins: 5 |
| Description | The trigger measures the high memory usage situation. The trigger conditions are met when memory usage is equal to or greater than 80% and the situation has lasted for more than (including) 5 minutes. |
Out of Memory Trigger
| ID | bw.montr.trigger.OutOfMemoryTrigger |
| Threshold | outOfMemoryThresholdPercent: 95 |
