I have a trouble with alerting in Grafana v.5.3.2.
I have DB monitoring that shows db locks.
I need to send alert if the count of locks is more then 0 during 1 min period.
Graph which shows locks has 2h period.
So I set the rule, created the lock and there is nothing happened.
It seems that Grafana analysis all elements of timeline, regardless the filter value.
Could you please help with it?
