Grafana dashboards

Dashboard directories

Directory	Purpose
charms/<charm>/cos_custom/grafana_dashboards/	Dashboards for a specific charm’s workload metrics
runner_grafana_dashboards/	Dashboards for runner VM host-level metrics (CPU, memory, disk, network)

Conventions

Dashboard JSON files should use __inputs to declare the data source (type prometheus). Setting "editable": false is recommended for clarity. Metric names follow the OpenTelemetry host metrics receiver Prometheus naming convention (for example, system_cpu_time_seconds_total).
