This release has been long in the making. We started on Alerting way back in March this year and it's finally released! Read more about all the highlights in the release here: http://grafana.org/blog/2016/11/09/grafana-4.0-beta-release/

Great work! Including a way to set grace periods will be really useful to prevent flapping on the metrics. ex, 'Alert When CPU > 95% for 10m'
One way to solve that problem is to reduce the series with min(). Ex http://play.grafana.org/dashboard/db/alerting-flappy?panelId...

This means that the lowest value for the last 5min of the serie have to be above 80% before the alert triggers.

Congrats on release! We've been using Grafana for a few years now, and personally built-in alerting is the only thing I would have added. Some may argue that this "violates" good concern separation practices, but honestly you are going to be alerting about the same data you feed to Grafana, so at the end of the day it makes a lot of sense. Call it a "two in one" if you will. Either way this will make monitoring with Grafana much more streamlined.
Note that keeping them separate has a benefit that when your 'Visualization' portal is down, your 'Alerting' systems are unaffected (and vice versa).

Collectd, telegraf. etc, can be configured to send the same metrics to your favorite TSDB and Alerting system (like riemann) in parallel.

Agreed with the sentiment re: streamlined experience.

We struggled a bit with whether or not it really "belonged" in Grafana, but we believe in alerting while "in the flow".

It makes a lot of sense (from an experience standpoint) to 'manage' alerting while you're 'managing' your dashboards, visualizations, and queries; you already have a sense of the data _right there_.

As someone who is not too familiar with Graphana but is tasked with deploying it (shortly), just curious about the alerting and some of what I can do with it? I will read through the release page, but it's fun to get it from the horses mouth, if you're still available to comment?
