collectd-nagios - Nagios plugin for querying collectd
collectd-nagios -s socket -n value_spec -H hostname [options]
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.
Path of the UNIX socket opened by collectd’s "unixsock plugin".
The value to read from collectd. The argument is in the form
Hostname to query the values for.
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.
When multiple data sources are selected from a value spec they can
be handled differently depending on this option. The values of the
No consolidation if done and the warning and critical regions
are applied to each value independently.
The warning and critical ranges are applied to the average of
sum The warning and critical ranges are applied to the sum of all
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.
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".
