Advanced Configuration Options for 'landscape.monitoring'

landscape:
  ...
  monitoring:
    active: false
    username: admin
    password: # password in clear-text
    customScrapeConfigPath: ./my-scrape-configs

Via the landscape.monitoring node, the monitoring feature can be activated. If activated, garden-setup will deploy a Prometheus and a Grafana instance in the cluster, as well as the Gardener Metrics Exporter. The monitoring is pre-configured and can not be adapted in the acre.yaml currently.

  • monitoring.active: if set to true (or anything else that is recognized as true by YAML), the monitoring components will be deployed. Defaults to false.
  • monitoring.username: the username for the ingress authentication to access the monitoring dashboards. Defaults to admin.
  • monitoring.password: the clear-text password for the ingress authentication to access the monitoring dashboards. Will be automatically generated and stored in the state (clear-text and hash) and export (hash only) of the monitoring/prometheus component, if not given.
  • monitoring.customScrapeConfigPath: if set, all yaml files in this folder will be added to the prometheus scrape_config. Preceding ./ can be omitted. Absolute aswell as relative paths like ../configs work.

Instead of username and password, monitoring.hash can be specified, containing a hash of the password. The hash should be created via htpasswd -nb <username> <password>.

Configure Prometheus remote_write

You can also configure Prometheus to use the remote_write feature for central logging. See the following configuration:

landscape:
  ...
  monitoring:
    ... # (see above)
    remoteWrite:
      url: # url path to remote_write endpoint
      username: # remote_write username
      password: # remote_write password
    externalLabels:
      key1: value1
      key2: value2
      ...

You can set credentials for the remote_write endpoint reachable at url using username and password. The optional user-defined key-value pairs underneath externalLabels are passed to the Prometheus external labels config option.
