How to send Alerts in Prometheus - Alertmanager

Ғылым және технология

Monitoring computers is very important and that should include alerts being sent out when something has gone wrong, but ideally even before a problem occurs
Now Prometheus does support alerting and you can even customise your own alerts
But it relies on a separate entity known as Alertmanager to actually send alerts to an email server for instance
And in this video we go over how to install and setup Alertmanager, how to configure Prometheus to use it, and how to create alerting rules in Prometheus

    hi Dave! thank you a lot for such detailed and understandable explanation. For me, as for the person who set up prometheus for the first time, the process of creating alerts became so much more easier after your video!

    Good to know the video was helpful I am really liking this Prometheus and Grafana combination Aside from the official exporters you can get, there are a lot of community developers out there

    thanks for your great & voluntary presentation. BUT .. if possible: I would appreciate a much larger, more noticeable, maybe colored pointer/cursor, moved with a calm (!) hand to allow me following more easily your brilliant thoughts.

    Thanks for the feedback I'm afraid my thought process and hand aren't usually in sync, which may explain the cursor movement

    Hello Dave, After installing the alert manager and setup the prometheus.yml file, my docker compose doesn't bring up the alertmanager container and prom container. Both containers always in restarting mode, any work around that ?

    Sounds like there's a typo, something missing or something not aligned in the config And although these work in my setup there may be something different in yours that needs adjustment I would suggest looking in the log files to see what the problem is e.g. docker container logs alertmanager docker container logs prometheus Something in those logs should explain why the container couldn't start
