AWS EC2 CPU Utilization Alert Issue


i have a question about grafana alerting

i have a alert rule
A query collect many AWS instances

for example
When instance A raises an alarm, if the alarm is not resolved,
the alarm does not occur even if instance B, which is collected from query A, passes the policy.

How to solve this problem?

Hi @juhyeon3182

I am not totally clear on the problem you describe, but it would seem you need to have two queries (A and B), with each being reduced to a single value (call it expression C and D).

Then, alert on the condition when section C is True (i.e. 1) and expression D is True. This looks like $C == 1 || $D == 1
