Is the alert a continuous event in the graph or just some alert point to trigger a alert email?

• Prometheus version:

  1.5.2

• Alertmanager version:

  latest

my prometheus config is as below:
global:
scrape_interval: 40s # By default, scrape targets every 15 seconds.
scrape_timeout: 30s

and my graph is like this:

I have a FOR 3-minute alert rule in my alert.rules file,
and in this picture, we have zero value, but it is not continuously all zero, it is partial.

It's best to ask usage questions on https://groups.google.com/forum/#!aboutgroup/prometheus-users

I've also some other rules in my alert.rules file that have the same situation.
And I checked the code in prometheus

In alerting.go
I do not know if the delete process is triggered under what intervals?
