双击 gcviewer-1.3x.jar就可以运行 GCViewer (gui) ,或者命令行运行（需要java 1.7 vm）：

 java -jar gcviewer-1.3x.jar 

命令行分析日志，并产生报表:

java -jar gcviewer-1.3x.jar gc.log summary.csv [chart.png]

Supported verbose:gc formats are:

- Oracle JDK 1.8 (experimental support) -Xloggc: [-XX:+PrintGCDetails] [-XX:+PrintGCDateStamps]
- Sun / Oracle JDK 1.7 with option -Xloggc: [-XX:+PrintGCDetails] [-XX:+PrintGCDateStamps]
- Sun / Oracle JDK 1.6 with option -Xloggc: [-XX:+PrintGCDetails] [-XX:+PrintGCDateStamps]
- Sun JDK 1.4/1.5 with the option -Xloggc: [-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
- IBM iSeries Classic JVM 1.4.2 with option -verbose:gc
- HP-UX JDK 1.2/1.3/1.4.x with the option -Xverbosegc
- BEA JRockit 1.4.2/1.5/1.6 with the option -verbose:memory [-Xverbose:gcpause,gcreport] [-Xverbosetimestamp]

Best results are achieved with: -Xloggc: -XX:+PrintGCDetails -XX:+PrintGCDateStamps
