Grafana Dashboards

There are multiple options how to add dashboard to Grafana. From chart version 21, this is extended with the option dashboards, which allows automatically loading dashboards from the Grafana marketplace or any other URL that returns a JSON with a Grafana dashboard. Scraping dashboards from configmaps continues to be possible and hasn’t changed.

Adding a dashboard via marketplace

Add the following part to your .Values:

dashboards:
  grafana:
    volsync:
      enabled: true
      failOnError: false
      b64content: false
      datasource:
        - name: "${DS_PROMETHEUS}"
          value: Prometheus
        - name: "${VAR_REPLICATIONDESTNAME}"
          value: ".*-dst|.*-bootstrap"
      marketplace:
        id: 21356
        revision: 3

Adding a dashboard via url

Add the following part to your .Values:

dashboards:
  grafana:
    truenas:
      enabled: true
      failOnError: false
      b64content: false
      datasource:
        - name: "${DS_MIMIR}"
          value: Prometheus
      url: https://raw.githubusercontent.com/Supporterino/truenas-graphite-to-prometheus/refs/heads/main/dashboards/truenas_scale.json

Some explanation of the values:

• enabled turn on/off the dashboard
• failOnError if enabled any failure during the download, decoding, or provisioning of the dashboard will cause the Grafana deployment to stop and error out, preventing Grafana from deploying.
• b64content automaticly decodes base64 encoded dashboards
• datasource: { name: "", value: "" } defines a list of mappings used to replace specific variables within a dashboard’s JSON file. You must consult the dashboard’s JSON structure to identify which variables need replacement. The variable substitutions must match their exact appearance in the JSON, including any brackets (e.g., ${...}). Be aware that specific deployment environments, such as Flux, might require escaping certain characters.
• id numbered id from https://grafana.com/grafana/dashboards/.
• revision numbered revision from https://grafana.com/grafana/dashboards/.
• url url where to download the dashboard from.

Note: It have to be marketplace: or url: both cannot be set at a time per dashboard.
