I was in charge of the stabilization test. I have to report what the GC is doing, but it's an unknown world with no experience at all. That's why I summarized what I googled so as not to be ashamed.
brew install maven git clone https://github.com/chewiebug/GCViewer.git cd GCViewer mvn clean install java -jar target/gcviewer-1.36-SNAPSHOT.jar
If you just run a simple program and take a GC log, In GCViewer, the time was too short and only vertical lines were displayed. For the time being, I understand how to use it, so it seems to be useful for analyzing GC logs for two days at work.
