Best and safest Java Profiler for production use? [closed]

Answer 1

Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java technology-based applications (Java applications) while they are running on a Java Virtual Machine (JVM). Java VisualVM organizes JVM data that is retrieved by the Java Development Kit (JDK) tools and presents the information in a way that enables you to quickly view data on multiple Java applications. You can view data on local applications and applications that are running on remote hosts. You can also capture data about the JVM software and save the data to your local system, and view the data later or share the data with others. This comes with Oracle JDK it self...

$ jvisualvm 

Answer 2

Take a look at Java Mission Control in conjunction with Flight Recorder. Starting with the release of Oracle JDK 7 Update 40 (7u40), Java Mission Control is bundled with the HotSpot JVM, so it is highly integrated and purports to have small effects on run-time performance. It has call tree functionality like Callgrind.

Another option is http://www.newrelic.com/. We have been using it in production for some time, and it seems to be pretty reliable and performant. Simple to setup (one .jar and a -agent commandline option).

Answer 4

I have been happy with jProfiler.

Answer 5

I prefer Java Flight Recorder. It causes almost no performance overhead and has a nice GUI. Add JVM parameters

-XX:+UnlockCommercialFeatures -XX:+FlightRecorder

-XX:StartFlightRecording=name=test,filename=test.jfr,dumponexit=true

and open the record with JMC.

Have you tried YourKit? It has almost all of the features you are looking for.
