Prometheus operations

v0.1.12

Server status, target health, alertmanager linkage, instant + range queries, rule listing, TSDB stats, plus admin-API actions for remediation: reload config, take snapshot, clean tombstones, delete series. Admin endpoints require --web.enable-admin-api + --web.enable-lifecycle.

Install

emisar pack install fetches this pack, re-validates it, and verifies its content hash against the --hash below — the exact bytes this page was rendered against, so a tampered copy is rejected — before copying it into the runner's packs dir. The command reloads a running daemon itself; no manual restart.

  • prom.delete_series exec high

    POST /api/v1/admin/tsdb/delete_series

    Mark series matching the matcher as deleted (tombstoned). Series no longer return from queries. Run clean_tombstones afterwards to actually reclaim disk. Use to remove cardinality-explosion mistakes or accidentally-recorded secrets. Match pattern is restricted to safe label-selector characters.

    GET /api/v1/status/flags

    Show server command-line flags.

  • prom.reload_config exec high

    POST /api/v1/admin/tsdb/snapshot

    View source on GitHub
