Threshold Formats

  • start <= end

The startvalue have to be less than the endvalue

  • start and ':' is not required if start is infinity>

If you set a threshold of '12' it's the same like ':12'

  • if range is of format "start:" and end is not specified, assume end is infinity

  • alert is raised if metric is outside start and end range (inclusive of endpoints)

  • if range starts is lower than end then alert is inside this range (inclusive of endpoints)
