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.
           percentage
               The warning and critical ranges are applied to the ratio (in
               percent) of the first value and the sum of all values. A
               warning is returned if the first value is not defined or if all
               values sum up to zero.
       -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 is smaller than min or bigger than max, a
           warning or critical status is returned, otherwise the status is
           success.
           The tilde sign (~) can be used to explicitly specify infinity. If ~
           is used as a min value, negative infinity is used. In case of max,
           it is interpreted as positive infinity.
           If the first character of the range is the at sign (@), the meaning
           of the range will be inverted. I. e. all values within the range
           will yield a warning or critical status, while all values outside
           the range will result in a success status.
           min (and the colon) may be omitted, min is then assumed to be zero.
           If max (but not the trailing colon) is omitted, max is assumed to
           be positive infinity.
       -m  If this option is given, "Not a Number" (NaN) is treated as
           critical. By default, the none consolidation reports NaNs as
           warning. Other consolidations simply ignore NaN values.
RETURN VALUE
       As usual for Nagios plugins, this program writes a short, one line
       status message to STDOUT and signals success or failure with its return
       value. It exits with a return value of 0 for success, 1 for warning and
       2 for critical. If the values are not available or some other error
       occurred, it returns 3 for unknown.
