A tool written in Javascript using the AngularJS framework to allow system administrators to upload Java VM garbage collection logs and graph memory usage.

The gc log viewer web application was written to see what is possible with HTML 5 and javascript and to deepen our understanding of gc log files. The ich that needed scratching was to provide our team with a easy to reach tool when the occasions arises thats requires an analyses of a JVM garbage log.

Historically this would require having to locate and install 3rd party software, if a manual review wasn't enough. Now its much easier and quicker for the team to get a quick overview of the log data.

In future we plan to add garbage collection pause times which is probably the most important graph after the total heap graph :)
