Hi, all NetBeans profiler versions support only Sun JVM, the profiler doesn't work with IBM JVMs. There is no way to workaround it. Jiri kolisto wrote:

Hi, Can NetBean Profiler be used with IBM JVM? I got the flowing exception then I trying to use it. There is also a bug related to the problem, but it isn't clear is any workaround for the case. http://www.netbeans.org/issues/show_bug.cgi?id=108681 Don't you know maybe some old version of netbeans profiler can work with IBM JVM? e.g. Is it make sense to take netbeans-6.1-ml-windows instead of RC2 Exception, version of JVM and NetBeans is below.

Re: How to filter out unnecessary class in Memory profiling

Jiri Sedlacek — 2008-11-05T20:55:19

Hi Alex, unfortunately the NetBeans profiler cannot limit number of instrumented classes for memory profiling. All the classes need to be instrumented which imposes significant profiling overhead for large applications. We are investigating how this could be improved, for now you can try to start the server in Monitor mode and after the startup change the profiling mode (Modify Profiling action) to Memory - this will at least speed up the server startup. FYI, you could also generate a heap dump (available also during Monitor mode - no profiling overhead) and browse it in HeapWalker - if there's a large and/or visible leak it will help you to realize who's preventing the objects from being gc'ed.

Hi, I have faced the following problem trying to find the source of memory leak in JEE application. My environment: Windows, Java 1.5, JBOSS 4.0.5, remote profiling Application almost hangs when profiler attaches with options required for leak detection (Record both object creation and GC, record stack trace for allocation) At console I can see that a lot of classes have been instrumented, I am not sure that all of them are really required for my case. I would like to narrow this set. In some scenario it also crashes, probably because of inconsistent instrumentation, some classes elimination also can resolve this problem. Are in NetBeans any ways to narrow profiled class set, ether which allocation is tracked or from which allocation happens? Thanks, Alex

Jess Holle — 2008-10-17T12:13:14

On a related note, see enhancement issue #113276. Setting root methods and getting full instrumentation is too much in a large system. Starting with rough profiling and moving to full instrumentation where the rough profiling indicates it worthwhile would be very helpful. Russ Petruzzelli wrote:

Enhancement Idea - HTTP / Socks Proxy for Web App Profiling.

Replogle, Andrew — 2008-10-13T20:31:11

Hi, I've used netbeans profiler in a limited scope as well as jprofiler and jprobe and had a thought for a feature that I've seen missing in everything I've worked with. When doing web application profiling, there's often a lot of package / class filtering that goes on depending on what you're trying to see. I was trying to figure out how you could assign the action of profiling to a timeline to figure out what happens when, because, at least in web application profiling, you want to see what are your suspect methods for a particular sequence or workflow. My suggestion is an HTTP or SOCKS proxy that the profiler would start up and all the requests / responses for the web application being profiled could be routed through. This way you could provide views for classes / methods based on which pages / actions are executed instead of having to wade through lots of data all at once. It could give you that time-line effect per-se. This could be useful for non-web apps too, if you went a SOCKS pr

Re: Call Sequence Tracing with profiler

Jaroslav Bachorik — 2008-10-07T20:07:51

Hi Compl, you might want to consider BTrace (http://btrace.dev.java.net) for this task. You can write you tracing code in the form of pure (annotated) java - you can instrument method calls identified by regex or inheritence and the call sequence tracing is quite easily achievable. There is even a VisualVM plugin for BTrace. In case you need help with BTrace feel free to write to the BTrace user list.

On the other hand profiler has all the necessary information for "Call Sequence Tracing", but those information are flatten into CPU snapshot, where there is only summary information. For "Call Sequence Tracing" you would have to remember every single method call, it will also create problem when you want to display such information one method can call other million times - this will create huge call tree, which will be hard to navigate. To implement it, you would need to write new shapshot infrastructure. It will be similar to CPU snapshot, but instead of summary time information, it will hold just the information about called methods.

Call Sequence Tracing with profiler

Compl Yue Compl — 2008-10-05T03:19:26

Hi list, I've spent a day or so investigating the possibility to trace Java method invocation sequences (to understand behaviors of an existing application upon some user actions) . Docs show Eclipse TPTP has some ability to generate Sequence Diagram in UML as profiling, but I've never succeeded with TPTP even to start profiling. The closest result I achieved so far is to view a CPU snapshot in NB profiler by sorting with the "Call Tree" column, however that won't show the exact order of method invocations in time sequence. I'd downloaded a source zip of whole NB and digged a little into profiler, my first idea had been to add a "Time Occurred" or "Sequence No." column to have the CCT sortable by occurrence sequence, but found no data field to back it. And I see the CCT nodes are *physically* reordered on sorting, and there's a default sort, so the *natural* order of CCT nodes is never available. Am I expecting the wrong thing from profiler? Or how is "Call Sequence Tracing" poss

Re: Problem getting the profiler working

Jiri Sedlacek — 2008-09-16T13:48:26

Yes, this is the expected behaviour. However, the fact that you had to copy the .so library manually to be able to access it points to the problem - the profiler is unable to use the .so library (and probably other files) on the network and that's why the calibration fails. You should either fix access to the network files (access rights?) or use a local user directory for profiling (probably more reliable). Jiri Dennis Weyland wrote:

Hi Jiri, thanks for your reply. Command line told me, that libprofilerinterface.so cannot be found.

Hi Dennis, make sure that there's no firewall blocking profiler ports (by default the profiler uses 5140 & 5141, maybe try to turn off the firewall during calibration just to be sure) and that no exceptions are logged in console / IDE logfile. If you won't be able to resolve the problem, please file a bug report at http://www.netbeans.org/issues/enter_bug.cgi?component=profiler and provide as much information as possible (at least the IDE logfile).
