grafana-oss

Grafana OSS core features — dashboards, panels, visualization types, data sources, template variables, alerting, annotations, provisioning, RBAC, service accounts, and configuration. Use when building dashboards, configuring data sources, setting up provisioning YAML, managing users and permissions, writing PromQL/LogQL/TraceQL in panels, or configuring Grafana server settings.

Template Variables

{
  "templating": {
    "list": [
      {
        "name": "namespace",
        "type": "query",
        "datasource": { "type": "prometheus", "uid": "prom" },
        "definition": "label_values(kube_pod_info, namespace)",
        "includeAll": true,
        "multi": true
      },
      {
        "name": "env",
        "type": "custom",
        "query": "production,staging,dev",

        "query": "1m,5m,15m,1h",
        "auto": true
