Actually you can find them in the jvmstat FAQ point 11.
1: Install and setup
For installation and setup problem pls refer to reference , the installation part.
2: Simple test
a) Test in local
For local test, here choose the Java2DDemo to demonstrate the usage of jps / jstat / visualgc
After the installation finished,
<1> Start the Java2DDemo swing java application
C: \> java-jar "C: \ Program Files \ Java \ jdk1.5.0_06 \ demo \ jfc \ Java2D \ Java2Demo.jar
<2> use jps to find the PID of the Java2DDemo, or you can find the PID in windows task manager.
C: \> jps
there is always has the Jps process. here the 5964 is PID of the Java2DMemo java application
<3> get the GC status by jstat and pipeline to a file to PID 5964, with 1000ms intervals and 1000 times.
C: \> jstat-gcutil 5964 1000 1000>> c: \ gc.log
for the usage of jstat you can get help by jstat-help and jstat-options
<4> Visual monitor the GC with visualgc
C: \> visualgc 5964
