/opt/metrics-collector/lib/collectd/usr/bin/collectd-nagios: invalid option -- '-'
Usage: /opt/metrics-collector/lib/collectd/usr/bin/collectd-nagios <-s socket> <-n value_spec> <-H hostname> [options]

Valid options are:
  -s <socket>    Path to collectd's UNIX-socket.
  -n <v_spec>    Value specification to get from collectd.
                 Format: `plugin-instance/type-instance'
  -d <ds>        Select the DS to examine. May be repeated to examine multiple
                 DSes. By default all DSes are used.
  -g <consol>    Method to use to consolidate several DSes.
                 See below for a list of valid arguments.
  -H <host>      Hostname to query the values for.
  -c <range>     Critical range
  -w <range>     Warning range
  -m             Treat "Not a Number" (NaN) as critical (default: warning)

Consolidation functions:
  none:          Apply the warning- and critical-ranges to each data-source
                 individually.
  average:       Calculate the average of all matching DSes and apply the
                 warning- and critical-ranges to the calculated average.
  sum:           Apply the ranges to the sum of all DSes.
  percentage:    Apply the ranges to the ratio (in percent) of the first value
                 and the sum of all values.
