Create a rules file

To use rules in Amazon Managed Service for Prometheus, you create a rules file that defines the rules. An Amazon Managed Service for Prometheus rules file has the same format as a rules file in standalone Prometheus. For more information, see Defining Recording rules and Alerting rules.

The following is a basic example of a rules file:

groups:
  - name: test
    rules:
    - record: metric:recording_rule
      expr: avg(rate(container_cpu_usage_seconds_total[5m]))
  - name: alert-test
    rules:
    - alert: metric:alerting_rule
      expr: avg(rate(container_cpu_usage_seconds_total[5m])) > 0
      for: 2m
