Download a copy of jvmstat3.0, which can be found on Google.

1) create a policy file under c: \: jstatd. All. Policy

Grant codebase "file :$ {java. Home}/../lib/tools. Jar" {permissionjava. Security. allpermission ;};

 

2) Run (take a 64-bit machine as an example) and download the sysinternals toolkit in advance.

Export xec-s jstatd-J-Djava.security.policy = C:/jstatd. All. Policy

3) Enter c: \ jvmstat after decompression to run

C: \ jvmstat \ BAT \ visualgc. CMD <Java progress PID >@< hostname>

You can also directly execute:

Jstat-gcutil-T <Java progress PID >@< hostname> 1000> mygcutillog.txt
