jvisualvm

I am trying to use the visualvm program that comes with the JDK to profile a webapp running in Tomcat. I have no problems connecting and everything looks nice and works properly in the GUI, except that my classes do not show. When profiling, using the CPU screen, I only see catalina and a few other classes' methods listed. How can I have visualvm show the method invocations of the webapp that Tomcat is running (rather than just Tomcat itself)? If it helps: This is with Tomcat 6.0.26 and JDK 1.6.0.22 Tomas Hurka First use the Sampler plugin . It will give you overall picture what is going on.

I would like to know if there is an equivalent of the excellent Java JVisualVM (included with JDK, the command is "jvisualvm") on the DotNet platform ? JVisualVM is a great tool that allows developers and admins to have really useful monitoring on any running Java application, here is some features that it has : Graphical view of the threads status Memory/CPU graphs Live heap dump CPU/Memory profiling Garbage Collector / JIT utilization graphs JMX calls Is there any equivalent on DotNet ? Thank you ! I don't know exactly what JVisualVM does, but it seems you are looking for this http://www.red

How can i change the application name in VisualVM ? I have multiple applications that where started from my IDE, but it's hard to distinguish them, there name are equal and the only difference is the PID. So i want to give them meaningful names, but the menu-item "Rename.." is disabled. How can i rename the application ? It seems to me like rename is only possible on snapshots -> descripion of snapshots Rename and Remove menu item are enabled only for snapshots not for applications. If you want to change the name displayed for the application you can set if through a JVM command line arg when

Related question: Garbage collector usage when upgrade from Java 6 + Tomcat 6 to Java 8 + Tomcat 8 I have a set of webapps, compiled with Java 8. If I run them in Tomcat 8, I get a lot of minor GC collections with a random memory allocation. In Tomcat 6 memory allocation is more linear and stable (idle in both cases, no traffic). Eden Space Tomcat 8: Eden Space Tomcat 6: Do you know why that happens? EDIT 1: These are the data from production environment with jdk 1.8 and Tomcat 8. CPU is really high almost always due to GC cycles. Any comments about that? EDIT 2: This is a heapdump analisis (1

I have an application where I want to be able to provide my own icon and descriptive text for jvisualvm. (I do not want to configure jvisualvm, just provide better metadata from my application) The best would be at runtime since we have distinct behaviour determined at runtime, which would be nice to have reflected in the label/icon. Makes it easier to 1) locate ourselves, but also 2) for endusers to locate in a support situation. I did search for this earlier, but did not locate this easily. Is it buried in the JMX-stuff? Suggestions? I have full control over the application in question.

I have simple Spring MVC application with a jsp and a controller class, deployed in a tomcat server. The setup works fine for multiple requests. I have named the controller class as com.mypackage.mvcController. Now I used jvisualvm to find the number of instances this particular controller class is created. It shows 2. Why number of instances of this particular controller bean is two? By default spring beans are singleton. Of course here the instances does not vary with multiple requests, but should have been one. Here is my configuration: web.xml <!DOCTYPE web-app PUBLIC "-//Sun Microsystems,

I'm trying to set up JVisualVm to monitor a Tomcat 6 instance (running on Ubuntu Server 10.04 LTS). I've seen other questions, but none of them directly answer my problem. I try to connect to Tomcat with JVisualvm and it comes back with a "Cannot connect" error - but there are TCP connections being made to the server; the server drops the connection after a short burst of traffic. I have already added this to /etc/default/tomcat6 and restarted tomcat6 # This enables JMX in order to permit VisualVM to profile the JVM.
