• libselinux-python on deployer host (only when deployer machine has SELinux)
• Grafana >= 5.1 (for older Grafana versions use this role in version 0.10.1 or earlier)

Alert notification channel example:

NOTE: setting the variable grafana_alert_notifications will only come into effect when grafana_use_provisioning is true. That means the new provisioning system using config files, which is available starting from Grafana v5.0, needs to be in use.

grafana_alert_notifications:
  notifiers:
    - name: Channel 1
      type: email
      uid: channel1
      is_default: false
      send_reminder: false
      settings:
        addresses: "example@example.com"
        autoResolve: true
  delete_notifiers:
    - name: Channel 2
      uid: channel2

Supported CPU Architectures

Historically packages were taken from different channels according to CPU architecture. Specifically, armv6/armv7 and aarch64/arm64 packages were via unofficial packages distributed by fg2it. Now that Grafana publishes official ARM builds, all packages are taken from the official Debian/Ubuntu or RPM packages.
