I have a Rails 3 application running in production. What are the tools available in the market to monitor response time and server health.
I am aware of New Relic but response time monitoring is available only in gold version which is $200/month.
For monitoring the health of the system I know of Server Density.
Any other tool?
I have been using ServerDensity for one year and I’m extremely satisfied. Recently a GitHub user released a Passenger plugin for ServerDensity.
If you want something more Ruby-oriented, have a look at Scout.
