Clément Désiles	e4d0812a69	fix(grafana): NUT dashboard instance variable ignores stale series ... The variable used label_values() which lists all instances across full retention, alphabetically sorting and auto-selecting the dead 127.0.0.1:9199 (relabeled to 'eaton' ~31h ago). Its stale series has no samples in the visible window so every panel rendered empty. Replace with query_result(count by (instance) (...)) which only surfaces live targets.	2026-09-06 23:51:22 +02:00
