Apache workers load warning
Apache workers in busy state approach the max workers count 80% workers busy on {{ $labels.instance }}
>>>
(sum by (instance) (
{state="busy"}) / sum by (instance) (
) ) * 100 > 80
The rule calculates the percentage of Apache worker processes that are in the busy state for each instance by dividing the number of busy workers (apache_workers{state="busy"}) by the total workers reported by apache_scoreboard, multiplies by 100, and fires when that percentage exceeds 80 % for an instance. When the busy‑worker ratio goes over 80 % on a given host, the Apache workers load alert is triggered, labeling the affected instance.
