NAME

munin-run - A program to run Munin plugins from the command line  

SYNOPSIS

munin-run [options] <plugin> [ config | autoconf | snmpconf | suggest ]  

DESCRIPTION

munin-run is a script to run Munin plugins from the command-line. It's useful when debugging plugins, as they are run in the same conditions as they are under munin-node.  

OPTIONS

--config <configfile>
Use <file> as configuration file. [/etc/munin/munin-node.conf]
--servicedir <dir>
Use <dir> as plugin dir. [/etc/munin/plugins/]
--sconfdir <dir>
Use <dir> as plugin configuration dir. [/etc/munin/plugin-conf.d/]
--sconffile <file>
Use <file> as plugin configuration. Overrides sconfdir. [undefined]
--paranoia
Only run plugins owned by root and check permissions. [disabled]
--ignore-systemd-properties
Do not try to detect and enforce the locally configured hardening flags of the ``munin-node'' service unit. This detection is skipped, if systemd is not enabled. The hardening flags may cause subtile surprises. For example ``ProtectHome=yes'' prevents the ``df'' plugin from determining the state of the ``home'' partition. [disabled]
--help
View this help message.
--debug
Print debug messages. Debug messages are sent to STDOUT and are prefixed with ``#'' (this makes it easier for other parts of munin to use munin-run and still have --debug on). Only errors go to STDERR.
--pidebug
Plugin debug. Sets the environment variable MUNIN_DEBUG to 1 so that plugins may enable debugging. [disabled]
--version
Show version information.
 

NOTES FOR SYSTEMD USERS

The ``munin-node'' service is usually started by systemd via a ``munin-node.service'' definition. Some distributions enable hardening settings in this service file in order to restrict the allowed set of activities for the ``munin-node'' process. This may cause surprising differences between the result of ``munin-run'' and the real ``munin-node'' service.

A popular example of such a surprising restriction is ``ProtectHome=yes'' combined with the ``df'' plugin. The restriction silently prevents the plugin from determining the status of mountpoints below /home.

``munin-run'' tries to mimic this behavior of ``munin-node'' automatically. Thus the execution of ``munin-run df'' should provide the same output as ``echo fetch df | nc localhost munin''.

If you want to debug potential issues of systemd restrictions, then you may want to use the parameters ``--ignore-systemd-properties'' and ``--debug''. Permanent overrides of systemd properties can be configured locally via ``systemctl edit munin-node''. See ``man systemd.exec'' for the documentation of systemd's properties.
