Endorsements

Look like the best deploying option I ever

found for Rails, GREAT!

The combination of Rails 2.0.2 (stable), JRuby 1.1 RC2, the Glassfish gem, and JDK 1.6 is not only breaking down enterprise barriers but speeding

up apps all over the place

leading the way to simple, scalable, no-hassle hosting for Ruby

web applications.

No mongrel packs to manage, no cluster of apps to monitor, and no WAR file relics to slow you down. "glassfish_rails myapp" and you're done; it's true one-step

deployment.

had no reliability and performance issues with

Glassfish

money is on JRuby (and Glassfish) for the long haul; if you haven't checked

out Glassfish yet, you're doing yourself a disservice!

Rails Monitoring ?

! Basic Monitoring

- jinfo – Prints Java System properties and VM CLI flags

- jmap – Shared object memory map or heap memory details

- jstack – Stack traces of Java threads

- jstat – Performance statistics on class, JIT compiler, GC

! Deep Dive

- jconsole / VisualVM

- NewRelic

- Five Runs
