JProfiler 6.0发布

This also means that when profiling a remote application server that should start up immediately without waiting for a connection from the JProfiler GUI, you do not have to transfer a config file to the remote server and specify it on the command line anymore. This simplifies remote profiling considerably.

Manual configuration of profiling has been simplified if you profile a 1.5+ JVM. Instead of the -agentlib VM parameter, a boot class path VM parameter and the modification of the native library path environment variable, you now simply specify a single JVM parameter and no other modifications are required. On Windows, with JProfiler installed in C:\Program Files\jprofiler6, the VM parameter is

-agentpath:C:\Program Files\jprofiler6\bin\windows\jprofilerti.dll=port=8849
       

Any remote session configured for port 8849 can now connect to the profiled JVM.

Usually, you will use an integration wizard to insert the VM parameter for profiling into your start script, or use an IDE integration to start profiling without any configuration. However, sometimes it is convenient to make changes manually. In that case, it is now much simpler to set up profiling than before.

Auto-tuning for dynamic instrumentation determines methods with disproportional overhead and suggests them for exclusion in the JProfiler GUI. Very short-running methods that are called very frequently can distort the overall numbers, because the time required to measure those methods takes much longer than the actual method itself. An example of such a method is the method in an XML parser that reads the next character. During profiling, you are notified of such overhead hot spots in the status bar.

By clicking on that notification or when the session is terminated, a dialog is shown that shows you the overhead hot spots and lets you add them to the list of ignored methods with one click. For your next profiling session, these methods will not distort overall numbers anymore.

Ignored method configurations can be reviewed and deleted in the filter settings.

The behavior of auto-tuning is configured with two parameters in the profiling settings. Auto-tuning can also be completely disabled for a session.

JProfiler snapshots can now by opened from IDE integrations. The main advantage is that you get source code navigation in the IDE for a snapshot that way.

Two new platforms have been added. Profiling is now also possible on FreeBSD x86 and Linux PPC  for both 32-bit and 64-bit JVMs.
