- prometheus : cible statique kadans-worker-mac (192.168.1.103:9105, tier laptop). Un scrape raté n'est PAS un incident : le Mac dort, up==0 raconte la latence — ne pas alerter dessus. ⚠ réserver l'IP au routeur (DHCP). - grafana : provider + dashboard « Kadans — jobs d'analyse » (uid kadans-jobs-analyse) : worker en écoute / dernier poll / file pending + âge du plus ancien (seuils 1 h / 24 h = le SLO), file par statut et publications par issue (couleurs de STATUT sémantiques), lanes exécutées et durée moyenne par lane. La façade, elle, arrive par les annotations de son pod (kadans-jobs#3) — zéro config ici. Co-Authored-By: Claude Fable 5 <[email protected]>
