NAME

       collectd-nagios - Nagios plugin for querying collectd

SYNOPSIS

       collectd-nagios -s socket -n value_spec -H hostname [options]

DESCRIPTION

       This small program is the glue between collectd and nagios. collectd
       collects various performance statistics which it provides via the
       "unixsock plugin", see collectd-unixsock(5). This program is called by
       Nagios, connects to the UNIX socket and reads the values from collectd.
       It then returns OKAY, WARNING or CRITICAL depending on the values and
       the ranges provided by Nagios.

ARGUMENTS AND OPTIONS

       The following arguments and options are required and understood by
       collectd-nagios. The order of the arguments generally doesn’t matter,
       as long as no argument is passed more than once.

       -s socket
           Path of the UNIX socket opened by collectd’s "unixsock plugin".

       -n value_spec
           The value to read from collectd. The argument is in the form
           "plugin[-instance]/type[-instance]".

       -H hostname
           Hostname to query the values for.

       -d data_source
           Each value_spec may be made of multiple "data sources". With this
           option you can select one or more data sources. To select multiple
           data sources simply specify this option again. If multiple data
           sources are examined they are handled according to the
           consolidation function given with the -g option.

       -g none|average|sum
           When multiple data sources are selected from a value spec they can
           be handled differently depending on this option. The values of the
           following meaning:

           none
               No consolidation if done and the warning and critical regions
               are applied to each value independently.

           average
               The warning and critical ranges are applied to the average of
               all values.

           sum The warning and critical ranges are applied to the sum of all
               values.

       -c range
       -w range
           Set the critical (-c) and warning (-w) ranges. These options mostly
           follow the normal syntax of Nagios plugins. The general format is
           "min:max". If a value if smaller than min or bigger than max a
           warning or critical is returned, otherwise okay is returned. min
           (and the colon) may be omitted and are then assumed to be zero. If
           max (but not the colon) is omitted max is set to positive infinity.
           If either min or max if set to ~ they are set to negative and
           positive infinity, respectively.

RETURN VALUE

       As usual for Nagios plugins this program writes a short, one line
       status message to STDOUT and signals success or failure with it’s
       return value. It exists with a return value of 0 for success or 1 or 2
       for warning and critical, respectively. If the values is not available
       or some other error occurred it returns 3 for "unknown".
