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.
