Budget: 800 UAH Deadline: 1 day
If all the data for the alarm is in Alertmanager it is better to use it, with those advantages I see in "Grafana Alerts" it is just what it can send to the chat along with the alarm image graphics. Otherwise, the alermanager will be better. I had something ready to help. It is only worth clarify that the alermanager himself cannot send at the TG by order, but only through an additional micro-service. The cousin can do it by himself.
In this comment you can't attach examples of those I've set on work, so if you look at my variants write in person.
