COLLECTD-NAGIOS(1)                           collectd                          COLLECTD-NAGIOS(1)



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".
