#state_over(thresholds, metric, min_state = 'ok') ⇒ Object

Calculate the state of a metric by comparing it to the given thresholds. The metric is compared to each threshold in turn, largest to smallest. The first threshold the metric is larger than is returned, or the ‘min_sate’ is returned.

  thresholds.sort_by {|e| -e[1] }.each do |threshold_entry|

#state_under(thresholds, metric, max_state = 'ok') ⇒ Object

Calculate the state of a metric by comparing it to the given thresholds. The metric is compared to each threshold in turn, smallest to largest. The first threshold the metric is smaller than is returned, or the ‘max_state’ is returned.
