Agent uses a SMTP check if the service listen on port 25.

To enable metrics gathering, ensure Bleemeo agent could run mailq command. This usually means to add the following to your exim configuration (e.g. /etc/exim4/conf.d/main/99_local):

queue_list_requires_admin=false

You will then need to fresh configuration (warning: the following will lost any local change in /etc/exim4/exim4.conf.template):

update-exim4.conf.template --run
update-exim4.conf
service exim4 restart

If some auto-detected parameters are wrong, you can manually override them by adding the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]

  # For an Exim running outside a container
  - type: "exim"
    address: "127.0.0.1"
    port: 25

  # For an additional Exim running outside a container
  - type: "exim"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 26

  # For an Exim running in a Docker container
  - type: "exim"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 25

Agent gathers the following metrics:

Metric	Description
service_status	Status of Exim
exim_queue_size	Number of mails queued
