Albertas Janulevicius - TNW 2008-08-06T20:02:00 http://comments.gmane.org/gmane.comp.java.netbeans.modules.profiler.user/599 Hi, I am new to NetBeans Profiler, so sorry if I ask a stupid question. I performed profiling of "Entire application" with several different filters, and looked at the total time spend in a particular method. I would expect the total time to be the same, but for each filter I get a different result. Furthermore, if a method is a bottleneck with one filter, with another filter it becomes much faster and some other method becomes the slowest one. Just want to stress that I am talking about the total time, not about the self-time (I understand that the self time can change depending on the filter). I tried to switch off the dynamic frequency scaling in BIOS, but still have the same problem. Could not find anything about this on the net... Could anyone please help me to understand what's going on? Albertas Janulevicius - TNW 2008-07-17T13:54:46 http://comments.gmane.org/gmane.comp.java.netbeans.modules.profiler.user/598 HI, Now we are working on porting NetBeans Profiler on Linux MIPS platform with CDC. We fully suceeded with CDC 72 revision. But on CDC rev 74 we faced with CVM crash in following case: 1) CDC is built with JIT enabled 2) Start our application with attached profiler 3) Connect from Netbeans IDE to CVM 4) Profiler instrument classes 5) crash Execution fails in *src\share\javavm\runtime\constantpool.c* file in * CVMprivate_cpExtractTypeIDFromUnresolvedEntry* function at line 294 : *typeIDIdx = CVMcpGetMemberRefTypeIDIdx(cp, cpIndex);* Crash is caused by assertation macros : +(CVMassert(CVMcpTypeIs(cp, idx, Fieldref) \+ +|| CVMcpTypeIs(cp, idx, Methodref) \+ *|| CVMcpTypeIs(cp, idx, InterfaceMethodref))* as argument tipe is incorrect (not equals to Fieldref or Methodref or InterfaceMethodref) Can anyone suggest any workarounds ?

I am trying to profile memory of a Tomcat 5.5.23 using JDK 1.5.0_12 on a Windows XP system. I modified the catatina.bat as described and am able to start the Tomcat instance (which has the application I am interested in deployed as usual) which waits until the profiler connects. However, after some time of progress where live profiling results are displayed the Tomcat instance either stops responding (which results in the Netbeans profiler asking wether to resume profiling or not) or I receive a " Profiler Agent Communication Thread OutOfMemoryError" in the cmd-shell i used to start catalina_nbprofiler.bat. I assume that the first case (Tomcat not responding) has the same cause as this behaviour always occurs when the heap size in the VM Telemetry view reaches about 80M. The webapp IŽm trying to profile is started with -Xms382m and -Xmx1024m. So my question is wether there are some parameters or configuration options to grant more memory to the profiler agent? I couldnŽt find any information on this issue... Thanks for any advice. Greetings Marcus _________________________________________________________________________ In 5 Schritten zur eigenen Homepage.

Our team is highly interested in the SPI mentioned in the issue to be implemented ASAP since we'd like to have a full functional profiler for our plugin. If you need more information from our team or have some suggestions what we could do to enhance JavaFX profiler functionality, we'd appreciate your input since we're not familiar with profiler code. If you'd like to try the JavaFX Script plugin to look into JavaFX profiler in its current state, you can use the daily builds: http://deadlock.netbeans.org/hudson/job/Java_FX_NB_plugin_Trunk_daily Thanks in advance, Mike. Michael Chernyshov 2008-03-26T15:50:24 http://comments.gmane.org/gmane.comp.java.netbeans.modules.profiler.user/584 It looks like NetBeans bug #100641 [http://www.netbeans.org/issues/show_bug.cgi?id=100641] should be re-opened -- based JDC bug #6546266 [http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6546266]. If so VisualVM definitely needs this particular fix. Having the profiler crash whenever you attempt to profile Tomcat is pretty hard to explain to a development team. They tend to simply decide the whole tool is untrustworthy. Plus there's the fact that profiling Tomcat is actually quite necessary at times... [Tomcat is just as effected by this issue as JBoss.] -- Jess Holle Jess Holle 2008-03-26T11:46:13 http://comments.gmane.org/gmane.comp.java.netbeans.modules.profiler.user/582 hello, i installed netbeans 5.5.1 under Windows with the profiler to profile weblogic8.1 the problem is i can't find the "profiler-ea-vm" i followed the instructions here http://profiler.netbeans.org/docs/help/5.5/j2ee_server_integration.html#WebLogic81 but i can't set up %MODJDK_HOME% as said here: # %MODJDK_HOME%, $MODJDK_HOME: path to the customized Profiler JDK, typically %NB_USERDIR%/modules/profiler-ea-vm.

But one thing that I waste time on is browsing the root to the gc for different instances of the same class to find out where the common connection is (usually looking for a listener that hasn't been cleaned up) in the heap dump. This means I have to walk the tree for each instance, look for likely common classes and try to find them in another instance. What would be really nice is to see an object graph (with nodes and edges) instead of a tree. This would mean I could quickly see the object that is holding on to my leaking class.

We are using NetBeans 6.0 on the client and 6.0 on the remote machine (taken from pack profiler-server-6.0-solamd64.zip). When the app isn't doing much the profiling works, however when load increases the remote profiler seems to crash with the output below. Profiler Agent Error: Exception when handling command from client: java.io.IOException: JFluid wire protocol error: code does not correspond to command or response. Value -1 The IDE claims that there is "No profiling sessions currently in progress", but the remote application does seem to still be running, albeit slowly. Does anyone have any ideas why this is happening and how we can get around?

I'll keep this email short and to the point, and if there's any interest then maybe we can take this forward. I'm a PhD student studying TM, and essentially I collect lots of execution profile data from runs of experiments to see the effects of 'new' ideas. I thought it would be a good idea to build a profiler similar to the nbprofiler for TM. I know of a variety of runtime statistics that could be collected, and I already have a pseudo-framework for gathering the data. All that's needed is to grab the data from the running Java application (not VM) and display them as graphs in the IDE, which boils down to developing Java code for netbeans. However, since you guys are experts, it might be much quicker for you than for me. Speed is important because TM is a hot topic at the moment, and I believe a visual profiler could lead to a conference publication, which I'd gladly share with any developer who would like to help. The conference is IISWC so work needs to move fast, and that's why an expert is a priority. I realise everyone is busy, but if you feel you have the time, let's say one full day just to trial and see how fast we progress, but realistically maybe 1 weeks work, then please reply with even a cursory hint of interest. I'll answer questions gladly. Thanks for reading. Bottom line: Build profiler that grabs various statistics from running Java application (not VM) and displays them in similar style to nbprofiler within netbeans (application is already an nb environment project). Conference publication possibility. Thanks in advance.
