Provisioning de dashboards (provider + JSON) : un dashboard logs avec sélecteur d'hôte + filtre regex + panneau logs + débit. Référence Loki par une VARIABLE de datasource (ds_loki), pas un UID codé en dur. Leçon : ajouter un uid explicite à une datasource déjà provisionnée casse le démarrage de Grafana (« data source not found ») → variable de datasource. Permet aux Viewers (dont testmail) de voir les logs sans accès Explore. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
