New Relic's integration with Heroku and great visualisation and reporting of key specs made it a no brainer
Overall Satisfaction with New Relic
We used New Relic to monitor a couple of web apps built with Heroku. We used it's availability monitoring feature, as well as the Apdex graphing for load testing.
- Used as main source of metrics for load testing
- The availability monitoring functionality keeps single dyno apps on Heroku awake
New Relic integrates perfectly with Heroku which was our primary use case.
To me, New Relic is the ne plus ultra of web app monitoring and is great for server monitoring, too.
