GCViewer is a Swing-based application that visualizes the verbose garbage collection output generated by the IBM and Sun Java VMs (-verbose:gc/-Xloggc:-flags).
The data can also be exported as CSV for forther processing with a spreadsheet application. Visualizing the data can help when one is tuning the garbage collector, especially the generation sizes and initial heap size.
Here are some key features of "GCViewer":
· Sun JDK 1.4/1.5 with the options -Xloggc:< file > [-XX:+PrintGCDetails]
· Sun JDK 1.2.2/1.3.1/1.4 with the option -verbose:gc
· IBM JDK 1.3.1/1.3.0/1.2.2 with the option -verbose:gc
Best results are achieved with: -Xloggc:< file >
GCViewer can also export the data in CSV (comma separated values) format, which may easily be imported into spreadsheet applications for further processing.
GCViewer has been developed with J2SE 1.4.
