Lots of updates this month including a rewritten alerts system, auto discovery, private packs, wildcard metric support and a bunch more of small changes.
In a previous blog post I promised to write about the difference between monitoring and alerting. Often they get bundled together when people talk about 'monitoring systems' as a whole. Monitoring is really just about collecting data. Storing state change information, time series metrics, maybe even some strings or json. Alerting is about getting notified for things that you care about. As is usually the case it goes much deeper than that.
