One of my favorite tools, FusionReactor 5, has just been updated. If you haven't heard of it, FusionReactor is an incredibly deep server monitor for ColdFusion servers. There's some incredibly cool new stuff in the release, including a new responsive UI, support for Hibernate and MongoDB, improved alerts, simpler JDBC testing and extended support for other J2EE platforms.
Even better: there is now a mobile app for FusionReactor!
And if you still haven't checked out the companion product, FusionAnalytics, make the time to do so now.
