how to get correct value after resolved alert

[zhao cruise]

I use the alertmanager to fire the alert, but I encounter problem that after the alert was resolved,  the notification alert include value which display the value is still above the value which was setting to alert.

That's correct. For an explanation why it must work this way, please read:

As a more general principle, you should consider turning off resolved message altogether. See:
