Postfix Delivery Status

Postfix Delivery Status screenshot 1

Dashboard that uses only logs from Loki as datasource. Logs will be processed on the server.

For extra large mail volumes, some values cannot be counted. In this case, consider increase Loki settings (see https://github.com/grafana/loki/issues/3045) .

Here is the approximate configuration of the promtail software:

clients:
  - external_labels:
      host_id: mailserver.domain
    url: http://192.168.1.1:3100/loki/api/v1/push

- job_name: mail
  static_configs:
    - targets:
      - localhost
    labels:
      job: mail
      __path__: /var/mail/mail.log
