# Load every *.json in this folder into Grafana as a sidecar dashboard ConfigMap.
# The Grafana chart's dashboard sidecar (sidecar.dashboards.enabled) watches for
# ConfigMaps labeled grafana_dashboard=1 in the monitoring namespace and imports them.
# Idempotent — re-run after adding/updating a dashboard JSON.

# The VictoriaMetrics board uses a `$ds` datasource variable that resolves to the
# default datasource (VictoriaMetrics), so no per-panel rewiring is needed.
