Useful in-depth tool for monitor and performance metrics
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.

Great tool for seeing what is happening in Java
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. (When) tracking down slow requests, I 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!”

we can evaluate the SQL statements quickly
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.
Helps me to find 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.”
