The high level of functionally available as well as the range of tools available. I also like the Cloud version which we have recently upgraded to on Ultimate version. I like the facility to view the SQL statements as well. Price is good value.

With the level of functionality it it not always easy to find the source of the problems and terminology is not always that user freindly.

There are very few tools as comprehensive when wanting to monitor the likes of Coldfusion. Suggest Utilize the Cloud Version

Performance Issues on Application and system freezes. We have also been having issues with Java heap/memory and the tool has helped find these. Also like the fact we can evaluate the SQL statements quickly.

Fusion Reactor is an innovative performance monitoring solution for Java applications in development, testing and production environments.it provides everything that Java developers need in an APM tool.

no dislikes at this moment, I have yet to find anything to dislike about FusionReactor APM

problems: find database queries which take time

benefits : before deploying an application to a production environment, it is easier to find problems and improve code quality.

The cloud service which I've recently started using is quite impressive, and tracks my commandbox docker containers automatically, including the automatic licencing stop/starts. The ability to see thread profiles, long running requests and length of things like cfhttp helps debug external APIs and identify where the potential bottlenecks are.

It does require a certain amount of technical knowledge to use. There's no point in looking at 26 graphs of JVM memory and garbage collection times if these things mean nothing to you. Configuration of certain features is by environment flag, so you have to know roughly what you're doing there too.

Try the developer edition first to see if you get along with it

Identifying slow running requests within a cloud infrastructure which would normally be inaccessible; profiling of long running requests down to the Java function level, introspecting database SQL and identifying inefficient SQL or repeated SQL.

Our development team uses the Developer Edition which saves time when trouble shooting issues during the development process. Developers can immediately determine what the server is doing and where to target their attention. The tool has aided us in identifying issues related to the memory usage, inefficient queries and much more. Bottom line, FusionReactor saves time and development costs.

Our operations team uses the FusionReactor Enterprise Cloud to monitor and diagnose performance issues in our production environment. The cloud product allows us to aggregate all our server’s metrics in an easy to use enterprise dashboard. This is invaluable when you run your applications in multiple data centers and many servers. It allows us to identify the server exhibiting a performance issue and quickly apply corrective action.

We leverage containers quite heavily in our development and production environments. The only issue we have run into is once a container is destroyed, it is marked offline and the cloud product does not show metrics or transactions any longer. In other words, the data displayed is only from running servers which makes it difficult to perform a postmortems.

If you are using containers in your infrastructure take the time to ask questions related to licensing. Make sure you describe in detail how you are running your development and/or production environments.

The tool allows us to isolate the root cause of issues in our applications. We save time when looking for issues whether relates query performance, dead locks, threads in our scheduled task runner or the Java VM.

I like how you can get in see what Java is going and the requests. This can be invaluable to track down code that might not be working well or finding code that is getting hung up on something.

I really don't any anything that I dislike.

Tracking down slow requests, and/or use FR to help me find the problems to fix them. With this tool you can get inside Java and see what is even happening!

The installation is simple - I typically go with the manual JAR install because it's super simple... drop a JAR on the filesystem and add a JVM argument.

Once running, the UI is easy to navigate - but not overly simplistic. You can drill down from high-level overview charts down to profiling stack-traces within a few clicks.

Easily the best tool I've used for root causes analysis on the JVM - and one of the cheapest too.

FusionReactor can do long-term trending but it's not it's strongest feature. In my experience, FusionReactor is much better at solving acute problems - sometime automatically through its crash protection features.

The cloud offering is improving all the time and does have better long-term trending (e.g. capacity planning)

Install and give it a go - there's a 14day free trial.

Automated installer is great if you have a GUI. If you're in a container or CLI only, manual install is super-simple.

Try the profiling features!

Root cause analysis (in production) of acute failures. When there's a problem in production sometimes it's not so simple to replicate - perhaps your data tier doesn't have the same volume or differentiating set of data; or perhaps the network topology, redundancy or traffic levels are different. FusionReactor adds no noticable overhead and gives a wealth of insight - it's always running and ready for us if we have a problem.
