Plugins for munin

This page lists a number of munin plugins that help you keep an eye on several services on your servers. The munin system is a network-wide monitoring and graphing framework that consists of client and server with plugins. Plugins may be written in any language you like.

Very Secure FTP Daemon

The vsftpd-rel plugin monitors the vsftpd log file and extracts successful and unsuccessful actions that get drawn into a graphic like this one later.

The following configuration is supported by this plugin. If the path to the log file or to the logtail program differs from the default they are configured in the plugin-conf.d directory.

   [vsftpd-rel]
   user root
   env.logfile /var/log/vsftpd.log
   env.logtail /usr/bin/logtail

HylaFAX

This plugin generates graphs for the active fax queue of HylaFAX. The path to the faxstat program is configured via a file in the plugin-conf.d directory if it differs from the default.

   [hylafax]
   user root
   env.faxstat /usr/bin/faxstat

Fan Speed via IPMI

This plugin monitors the fan speed that is reported via IPMI (Intelligent Platform Management Interface). IPMI is an open standard for monitoring, logging, recovery, inventory, and control of hardware that is implemented independent of the main CPU, BIOS, and OS. If the path to the ipmitool differs from the default it is configured via a file in the plugin-conf.d directory.

   [ipmi_fans]
   user root
   env.ipmitool /usr/bin/ipmitool

Postfix Mail Throughput

This plugin visualises the throughput of mail by the Postfix mail server. The graph consists of delivered and rejected mails separated by the SMTP reject code (553, 550, 501, 450 etc.). It is a rewrite of the old plugin to work with Munin::Plugin and handle several frontend servers well. The path to the log file can be adjusted.

   [postfix_mailstats]
   user root
   group adm
   env.logdir /var/log
   env.logfile mail.log
