JVisualVM features not supported on this VM
1011450May 28 2013 — edited May 28 2013I am running Ubuntu 12.04 and have Java JDK 1.7.0 installed.
In the jvisualvm Monitor tab, it says "Not supported for this JVM"
In the Sampler tab I get these messages:
CPU sampling:
Not available. Failed to create JMX connection to target application. Use 'Add JMX Connection' action to attach to the application.
Memory sampling:
Not available. Failed to read objects in target application. Check the logfile for details (use Help | About | Logfile).
The Overview tab says:
JVM: Java HotSpot(TM) 64-Bit Server VM (23.21-b01, mixed mode)
Java: version 1.7.0_21, vendor Oracle Corporation
Java Home: /usr/lib/jvm/jdk1.7.0_21/jre
JVM Flags: <none>
The About/Details popup says this:
Version: 1.7.0_21 (Build 1342-120605); platform 20120605-unknown-revn
System: Linux (3.2.0-44-generic) , amd64 64bit
Java: 1.7.0_21; Java HotSpot(TM) 64-Bit Server VM (23.21-b01, mixed mode)
Vendor: Oracle Corporation, http://java.oracle.com/
Environment: UTF-8; en_US (visualvm)
Userdir: /home/bwroga/.visualvm/7u6
Clusters:
/usr/lib/jvm/jdk1.7.0_21/lib/visualvm/platform
/usr/lib/jvm/jdk1.7.0_21/lib/visualvm/visualvm
/usr/lib/jvm/jdk1.7.0_21/lib/visualvm/profiler
So it seems like jvm and the process I'm monitoring are running on the same vm.
