GCViewer
GCViewer is a free open source tool to visualize data produced by the Java VM options -verbose:gc and -Xloggc:. It also calculates garbage collection related performance metrics (throughput, accumulated pauses, longest pause, etc.). This can be very useful when tuning the garbage collection of a particular application by changing generation sizes or setting the initial heap size.
GCViewer can also export the data in CSV (comma separated values) format, which may easily be imported into spreadsheet applications for further processing.
