These days the development of software is a rapidly changing process. The introduction of cloud hosting and containerization has made big applications running in your server room a thing of the past. Where before you would maintain one or two big projects with a team of engineers dedicated to a single project. Now you have […]

For some months we have been having problems with maven-surefire-plugin showing very strange exception stack traces. After some searching, I found out that maven-surefire-plugin has a trimStackTrace configuration option which is set to true by default. See http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#trimStackTrace I have no idea who thought that removing part of the stack trace would be a good […]

FusionReactor is able to track asynchronous requests made with several different libraries, examples of which include: Redisson MongoDB Kafka Java Clients OkHttp Apache HttpClient How FusionReactor Displays this Information The response to the asynchronous request is tracked with ‘Callback’ as the subflavour. This is attached as a linked transaction (indicated by the small linked chain […]

FusionReactor is used to monitor many ColdFusion servers but our support team keeps seeing an issue that FusionReactor cannot solve. This issue is that some of the ColdFusion classes, for the template cache, become corrupt.  This corruption isn’t caused by ColdFusion itself but when users or Windows Updates shut down the running instance.  If ColdFusion […]

In that article I specifically avoided talking about one of the biggest culprits of slow pages – database queries. My history with ColdFusion goes back to about version 2 and even back then […]

Have you wished you could change the name given to your monitored instance in FusionReactor (the name that appears in the UI and various reports/emails)? Did you know you could change it easily, on the fly, from within the instance and without need of restarting your instance?

Finding (and Fixing) Your Slow ColdFusion Pages with FusionReactor In my last article I described how I wanted to help introduce FusionReactor to ColdFusion developers with a special focus on helping solve practical problems and navigating terminology that may not be terribly familiar with if you haven’t used Java before. In that first article I […]

Getting Started with FusionReactor (for ColdFusion Devs) As a ColdFusion developer, you may know that it’s running as a J2EE server but also may have zero to no idea what that means in a practical sense. ColdFusion has always been easy to use, especially for developers from a non-traditional background, and this sometimes means there’s […]

In this post Matthew Clemente discusses FusionReactor for Docker Swarm. This article originally appeared on his blog FusionReactor for Docker Swarm (Part 1, Installation)   Moving a standard ColdFusion installation to Docker Swarm requires rethinking – and frequently rewiring – portions of our infrastructure. Today, that means reconfiguring how we deploy FusionReactor to monitor our […]
