Dovecot Input Plugin

The dovecot plugin uses the Dovecot v2.1 stats protocol to gather metrics on configured domains.

When using Dovecot v2.3 you are still able to use this protocol by following the upgrading steps.

Configuration:

# Read metrics about dovecot servers
[[inputs.dovecot]]
  ## specify dovecot servers via an address:port list
  ##  e.g.
  ##    localhost:24242
  ## or as an UDS socket
  ##  e.g.
  ##    /var/run/dovecot/old-stats
  ##
  ## If no servers are specified, then localhost is used as the host.
  servers = ["localhost:24242"]

  ## Type is one of "user", "domain", "ip", or "global"
  type = "global"
  
  ## Wildcard matches like "*.com". An empty string "" is same as "*"
  ## If type = "ip" filters should be <IP/network>
  filters = [""]

Metrics:

• dovecot
  • tags:
    • server (hostname)
    • type (query type)
    • ip (ip addr)
    • user (username)
    • domain (domain name)
  • fields:
    • reset_timestamp (string)
    • last_update (string)
    • num_logins (integer)
    • num_cmds (integer)
    • num_connected_sessions (integer)
    • user_cpu (float)
    • sys_cpu (float)
    • clock_time (float)
    • min_faults (integer)
    • maj_faults (integer)
    • vol_cs (integer)
    • invol_cs (integer)
    • disk_input (integer)
    • disk_output (integer)
    • read_count (integer)
    • read_bytes (integer)
    • write_count (integer)
    • write_bytes (integer)
    • mail_lookup_path (integer)
    • mail_lookup_attr (integer)
    • mail_read_count (integer)
    • mail_read_bytes (integer)
    • mail_cache_hits (integer)
