collectd-postfix plugin

This plugin collects mail metrics from the postfix mail log. I have only tested this on CentOS 6 with Python 2.6.6

Example data in Grafana

Supported Platforms

Tested on

• CentOS 6 (Python 2.6) with collectd 5.5.3

Usage

Follows standard collectd-python plugin configuration. You need to make sure your collectd binary was compiled with python support first.

• Drop collectd-postfix.py into <COLLECTD_ROOT>/share/collectd/ - or wherever you store plugins
• Configure the plugin in your collectd config <COLLECTD_ROOT>/etc/conf.d/postfix.conf or however you include plugins

Below is an example module config. Current allowed options are:

- Verbose (boolean) - use verbose logging 
- Maillog (string) - location of postfix mail log
- CheckMailQ (boolean) - check the postfix mail queue (shells out with subprocess)

<LoadPlugin python>
    Globals true
</LoadPlugin>

<Plugin python>
    # collectd-postfix.py is at /opt/collectd/share/collectd/collectd-postfix.py
    ModulePath "/opt/collectd/share/collectd/"
    Import "collectd-postfix"
    <Module postfix>
      Verbose false
      Maillog "/var/log/maillog"
      CheckMailQ true
    </Module>
</Plugin>
