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 it's 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.
