How can I set up alerting in Prometheus for my metrics?

To set up alerting in Prometheus, you need to define alerting rules in your configuration file. Do you have a specific metric in mind?

Yes, I want to alert when CPU usage exceeds 80%.

You can create an alerting rule like this: alert: HighCpuUsage, expr: cpu_usage > 80, for: 5m. Would you like help with the configuration file?

Yes, please show me how to add it to the configuration.

You can add the rule under the groups section in your alerting_rules.yml file. It should look like this: groups: - name: cpu-alerts rules: - alert: HighCpuUsage expr: cpu_usage > 80 for: 5m. Do you need assistance with testing the alerts?
