Alert is not fired

[sharpSteff]

I have the strange behavior, that my alert is never fired, when the condition is met:

Do I miss something?

@sharpSteff I'm curious what does the alert history show on the right of that second screenshot? Does it show red bars, grey bars or green bars? Also to note, if it's a 1 day alert interval, it'll take a day for the alert to fire.

@MikeShi42 gray bars

How do I change the day alert interval ?

@sharpSteff You can change the alert interval with the dropdown UI

@wrn14897 Ah now I understand. My query counts errors in a certain span, which is basically just a little spike since its a one time event. That can never fullfil the Alert criteria.
