Interesting - we're using New Relic and reasonably happy, but might give this a try. It'd be nice to get more concrete comparisons on features compared to them

Interesting - we're using New Relic and reasonably happy, but might give this a try. It'd be nice to get more concrete comparisons on features compared to them - New Relic is a pretty huge product and we use it for things like alerting PagerDuty based on error rates and response times as well as performance, and has lots of powerful reports etc. Ironically, one of the biggest problems with New Relic is that their interface is bloated and performs poorly :)
