What metrics, logs, and alerts matter most for operating OpenTofu?

Monitoring OpenTofu should not stop at process uptime. Build dashboards around service-level impact and the internal mechanics that drive that impact. For OpenTofu, that means turning state management and locking, provider/module registry compatibility, the plan/apply workflow, drift detection, workspaces, and migrating existing Terraform configurations into concrete telemetry. Useful alerting separates symptoms from causes: symptom alerts page humans when users or delivery pipelines are affected; cause alerts help responders identify resource exhaustion, bad configuration, certificate expiry, or dependency failure.

For SRE-quality operations, connect alerts to runbooks. Every alert should answer what changed, what is impacted, where to look first, and what action is safe. Avoid noisy alerts that page on harmless transients, and prefer burn-rate or sustained-threshold logic when the signal represents an SLO.
