munin−run − A program to run Munin plugins from the command line
munin-run [options] <plugin> [ config | autoconf | snmpconf | suggest ]
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.
−−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.
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.
