Learn about configurations >

• cpu | string

  K8s cpu resource limit, e.g. "1" or "500m". Default is unset (no limit). This value is used for the "limits" portion of the resource requirements (the "requests" portion is automatically deduced from it). See https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

• evaluation_interval | string

  Default: 1m

  How frequently rules will be evaluated.

• log_level | string

  Default: info

  Prometheus server log level (only log messages with the given severity or above). Must be one of: [debug, info, warn, error, fatal]. If not set, the Prometheus default one (info) will be used.

• maximum_retention_size | string

  Default: 80%

  The maximum storage to retain, expressed as a percentage (0-100) of the PVC capacity (e.g. "80%"). The percentage value is then converted to bytes and passed to prometheus with the `--storage.tsdb.retention.size` argument. Default is 80%.

• memory | string

  K8s memory resource limit, e.g. "1Gi". Default is unset (no limit). This value is used for the "limits" portion of the resource requirements (the "requests" portion is automatically deduced from it). See https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

• metrics_retention_time | string

  Default: 15d

  How long to retain samples in the storage. Units Supported: y, w, d, h, m, s

• metrics_wal_compression | boolean

  This flag enables compression of the write-ahead log (WAL). Depending on your data, you can expect the WAL size to be halved with little extra cpu load.

• web_external_url | string

  DEPRECATED. This config option is no longer used, in favor of "skipPrefix". The URL under which Prometheus is externally reachable (for example, if Prometheus is served via a reverse proxy). Used for generating relative and absolute links back to Prometheus itself. If the URL has a path portion, it will be used to prefix all HTTP endpoints served by Prometheus. The URL provided must point to the root of the Prometheus web application, e.g.: http://foo.bar/ Note, do *not* set this configuration to a specific to an API path, e.g., http://foo.bar//api/v1/write # DO NOT TRY THIS AT HOME This configuration option takes precedence over the URL provided over the "ingress" relation.
