> This results in other systems wanting to do alerting, making it tough to compare tools. I'd think you've hit the nail on the head, every monitoring system has to do a bit of everything such as alerting, machine monitoring, and graphing; rather than focusing on just doing one thing and doing it well. Prometheus comes with a powerful data model and query language, few existing systems support the same (e.g. Atlas and Riemann have the notion of a query language and labels) so we have to do a bit of everything to produce a coherent system. I think a separate common alert manager would be good if we could combine, currently in practice that role isn't being done as you rely on de-duplication in a tool such as Pagerduty with support for silencing alerts not being unified.
