Dovecot monitoring with Netdata

Provides statistics information from Dovecot server.

Statistics are taken from dovecot socket by executing EXPORT global command. More information about dovecot stats can be found on project wiki page.

Module isn't compatible with new statistic api (v2.3), but you are still able to use the module with Dovecot v2.3 by following upgrading steps..

Requirement: Dovecot UNIX socket with R/W permissions for user netdata or Dovecot with configured TCP/IP socket.

Module gives information with following charts:

  1. sessions

    • active sessions

  2. logins

    • logins

  3. commands - number of IMAP commands

    • commands

  4. Faults

    • minor
    • major

  5. Context Switches

    • voluntary
    • involuntary

  6. disk in bytes/s

    • read
    • write

  7. bytes in bytes/s

    • read
    • write

  8. number of syscalls in syscalls/s

    • read
    • write

  9. lookups - number of lookups per second

    • path
    • attr

  10. hits - number of cache hits

    • hits

  11. attempts - authorization attempts

    • success
    • failure

  12. cache - cached authorization hits

    • hit
    • miss

Configuration

Edit the python.d/dovecot.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/dovecot.conf

Sample:

localtcpip:
  name     : 'local'
  host     : '127.0.0.1'
  port     : 24242

localsocket:
  name     : 'local'
  socket   : '/var/run/dovecot/stats'

If no configuration is given, module will attempt to connect to dovecot using unix socket localized in /var/run/dovecot/stats
