Alert thresholds depend on the nature of your applications. Some queries may have arbitrary tolerance thresholds. Building an efficient monitoring platform takes time. 😉

S.M.A.R.T Device Monitoring Prometheus Alert Rules

8 Prometheus alerting rules for S.M.A.R.T Device Monitoring. Exported via smartctl-exporter. These rules cover critical and warning conditions — copy and paste the YAML into your Prometheus configuration.
