Threshold and ranges

A threshold is a range with an alert level (either WARNING or CRITICAL). Thresholds will be set comma separated in the following order:

  • open slots
  • busy workers
  • idle workers
  • requests per second
  • bytes per second
  • bytes per request

A range is defined as a start and end point (inclusive) on a numeric scale (possibly negative or positive infinity).

This is the generalised format for ranges:



  • start ≤ end
  • start and ":" is not required if start=0
  • if range is of format "start:" and end is not specified, assume end is infinity
  • to specify negative infinity, use "~"
  • alert is raised if metric is outside start and end range (inclusive of endpoints)
  • if range starts with "@", then alert if inside this range (inclusive of endpoints)


Setting non for one of them is also possible. The following example sets the threshold for busy workers to WARNING for at least 10 busy workers and CRITICAL to at least of 25 busy workers: -H localhost -w ,10,,,, -c ,25,,,,

To additionally set the threshold for _openslots to WARNING when at or below 10 and CRITICAL when at or below 5: -H localhost -w 10:,10,,,, -c 5:,25,,,,
