The goal of an alert is to let you know when there is a problem you need to attend to. The challenge is to set alert condition thresholds so that you are not alerted too much or too little. In general, the steps are as follows:
- Establish a baseline - Start with a basic system-defined alert profile applied and run APM for a long enough period (at least a couple of days) that you can see typical performance patterns appearing in the performance charts. The following system-defined alert profiles are a good starting point depending on what you are monitoring:
- Adjust alerts if necessary - Depending on the baseline performance observed, you may want to customize an alert profile such that alert condition thresholds are violated when they are outside of the normal operating range and at a point where you would like to be alerted. If you receive too may alerts, fix the issue causing the violated alert threshold or increase the alert threshold. If you do not receive alerts but users are reporting issues, lower the appropriate alert threshold.
