Manage Prometheus alert rules and silences.

nself alerts <subcommand> [flags] [args]

nself alerts lists configured Prometheus alert rules, silences alerts for a window, and fires synthetic test alerts to validate routing through Alertmanager. It is the operator-facing wrapper for the monitoring stack provisioned by nself (Prometheus + Alertmanager).

alerts list reads the bundled rule set and prints each rule with its severity (P1, P2, P3), for duration, summary, and PromQL expression. alerts silence posts a silence to Alertmanager with a duration and required reason. alerts test injects a synthetic firing alert through the Alertmanager API so on-call rotation, notification channels, and dashboards can be exercised end-to-end.

Use this command after editing alert rules or when validating that paging integrations (PagerDuty, Slack, email) are wired correctly.

# List all alert rules

# List only critical (P1) rules as JSON

# Fire a test alert so on-call rotation can verify routing
nself alerts test HighErrorRate
