Dovecot collector

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


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


name : 'local'
host : ''
port : 24242

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


To troubleshoot issues with the dovecot module, run the python.d.plugin with the debug option enabled. The output will give you the output of the data collection job or error messages on why the collector isn't working.

First, navigate to your plugins directory, usually they are located under /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata

Now you can manually run the dovecot module in debug mode:

./python.d.plugin dovecot debug trace
