You just need to include it in the query you are sending the Prometheus API.

It is expected that counters will reset when a service restarts, so you 
don't need to do anything. Prometheus handles counter resets 
automatically when you are using functions like rate().

Re: [prometheus-users] exporter crashes, multiple up-metric-related alerts fire

[Brian Candler]

Of course, you don't get that problem if you turn off the sending of 
"resolved" notifications completely.

[Mario Cornaccini]

of course !
thank you;

totally overlooked that, because at some point we went for group_by: [...], 
because we didn't like how when 1 alert of a group resolves, that we then 
get a new notification, that just the remaining firing one is active;
(a matter of taste somehow, i'd say); 'guess we cannot have the cake and 
eat the cake,so to say ;-)

cheers,fil
