Rend le comportement des automatisations VISIBLE et diagnosticable — logs structurés JSON, compteurs de fin de run, heartbeats, alertes sur seuil — pour les timers systemd, tâches planifiées, pipelines de veille et scripts maison. À utiliser quand on ajoute du logging ou de l'alerting, quand on déploie une automatisation et qu'il faut prouver qu'elle tourne, ou quand un incident survient sans trace exploitable. Déclencheurs : "ajoute des logs", "comment savoir si ça tourne", "instrumente…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Observabilité & instrumentation

Objectif : répondre à « ça a tourné, et qu'a-t-il fait ? » SANS relancer. Règles citées (R34 : tout
artefact opérationnel est inscrit au vault ; R48 : logging de session ; R71 : exit 0 seulement si
l'effet annoncé a eu lieu) — définitions dans `${CLAUDE_PLUGIN_ROOT}/references/regles.md`.

## Les 3 questions de toute automatisation
1. **A-t-elle tourné ?** — dernière exécution, succès/échec, durée.
2. **Qu'a-t-elle produit ?** — compteurs : N traités, N ignorés, N erreurs.
3. **Qu'est-ce qui a cloché ?** — erreurs avec contexte (fichier, entrée, exception), pas juste un code.

## Pratiques
- **Log structuré** : une ligne JSON par événement, horodatage ISO 8601 UTC, append-only, flush
  immédiat. Squelette prêt à copier : `scripts/structlog_snippet.py` (stdlib, ~60 lignes ;
  `python3 structlog_snippet.py --demo` pour voir la sortie).
- **Événements minimaux** : `run_start` (paramètres), `run_end` (compteurs + durée), `error`
  (contexte + exception), `skip` (raison). Nommer les événements en snake_case stable — c'est ce
  qu'on grep.
- **Heartbeat** pour les services longs : un événement `heartbeat` toutes les N minutes, ou un fichier
…

How to install

The exact contents, by fingerprint
mdr add geekfamilycorp/tricorderkit/observability-and-instrumentation@sha256:80f8becff923a2cd

The line at the top of this page pins the label v1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
