With http://bosun.org http://bosun.org (Stack Overflows alerting system: Expressions, Notification Templates, Historical testing etc) we have hedged our bets by adding in different query functions to the expression language. Currently it can query: - OpenTSDB - InfluxDB - Graphite - Elastic (Expects to be populated by logstash) OpenTSDB was the original time series database so that has some extra UI features compared to others for graphing. My hope is that InfluxDB will mature to the point in availability that we can use it and ditch the hbase dependency. But Currently OpenTSDB is the best option for us.
