Alerts: how to manage host name with Loki? (count by hosts, descritption)

Dear grafaners,

I’ve build few alerts but still cannot understand how to manage the host:

  • I just want to see the alert when the sum for ONE host is more than a value
  • I send the alert to rocketchat and I want to see the host name in the description on order to know immediately where is the problem.

Current alert is:
sum(count_over_time({host=~“.+”}|~ " LONG :" [$__range]))

And condition is "When count() is A is above 10 then.

Any idea please? Thanks in advance.
