Monitoring of Monitoring

Once a Prometheus-based monitoring stack was deployed for a Kubernetes-based SaaS product, an alerting rule failed to be deployed, leading to delays in issue detection. To address this issue, the SRE implemented Monitoring of Monitoring (MoM) to continuously monitor the alerting lifecycle within the monitoring stack. By validating alerting rules during CI/CD and monitoring configuration reloads, the team ensured timely alerting notifications and improved visibility into the system.
