A couple of us from Prometheus met with Josef from Chronix last week. I haven't tried Chronix yet, but it sounds great for what they're doing. It's currently used for industrial manufacturing monitoring (think car production lines), with a focus on offline anomaly detection. However, there are no live queries yet - it's more about offline number crunching and storing all data points forever. They are also Prometheus users, so they're interested in having Prometheus as a live monitoring system and feeding long-term data into Chronix once the interfaces for that in Prometheus become available.
