git clone https://github.com/jewes/gchisto.git
cd gchisto
set JAVA_HOME=d:\pierre\Java\jdk1.7.0_79
d:\apps\apache-maven-3.3.3\bin\mvn clean install
cd target
java -jar gchisto-1.0.1-SNAPSHOT.jar
beware that it requires also the jars in the lib folder - they are included in the MANIFEST.MF file...
I have run the tool on some PROD gc.... I was quite pleased with the result, you get almost all the information you need to assess how bad the situation is - of course you will never know WHAT caused your trouble, but you know when and how much CPU and wait time you are paying for Minor GC and Full GC.
