Dovecot Input Plugin

The dovecot plugin uses the dovecot Stats protocol to gather metrics on configured domains. You can read Dovecot's documentation here

Configuration:

# Read metrics about dovecot servers
[[inputs.dovecot]]
  # Dovecot servers
  #  specify dovecot servers via an address:port list
  #  e.g.
  #    localhost:24242
  #
  # If no servers are specified, then localhost is used as the host.
  servers = ["localhost:24242"]
  # Only collect metrics for these domains, collect all if empty
  domains = []

Tags:

server: hostname
domain: domain name
