2 jconsole.exe, jvisualvm.exe tools
Only local monitoring is discussed here, and RMI needs to be configured for remote monitoring.
2.1 Tool Directory
Through jconsole and jvisualvm, it is more convenient to view the error information of the virtual machine, such as stack overflow StackOverflowError, memory overflow OutOfMemoryError and so on.
2.2 Introduction to the use of the jconsole tool
2.2.1 Run jconsole.exe,
Select the local process, you can observe all the virtual targets of this machine, I arbitrarily select the running weblogic.server to enter. Since my weblogic is a server and a cluster node, there are two weblogic.server
2.2.2 You can view, memory, thread, class, VM, Mbean through jconsole
2.3 Introduction to jvisualvm tool
If you enter the software if it prompts that the java application cannot be detected, modify the system environment variables. Both Aministrator and system variables need to modify temp and tmp.
temp=c:\windows\temp
tmp= c:\windows\temp
