G1 garbage collector log analyzer
提问by Edge
I am looking for GC log analyzer for Garbage First collector. Many people have mentioned "IBM Pattern Modeling and Analysis Tool for Java Garbage Collector (PMAT)" but it doesn't seem to be compatible with G1 with Oracle JDK7. Can any one share which tools you have used for analyzing gc logs graphically.
我正在寻找垃圾优先收集器的 GC 日志分析器。很多人都提到了“IBM Pattern Modeling and Analysis Tool for Java Garbage Collector (PMAT)”，但它似乎与 G1 和 Oracle JDK7 不兼容。任何人都可以分享您使用哪些工具以图形方式分析 gc 日志。

The latest Mission Control, available as part of Java 7u40, is compatible with all Hotspot GC algorithms and is able to analyze and view the GC activity.
最新的Mission Control作为 Java 7u40 的一部分提供，与所有 Hotspot GC 算法兼容，并且能够分析和查看 GC 活动。

Look at the Memory Tabin Java Mission Control, it will graph heap usage, live set, GC pauses etc. for G1.
查看Java Mission Control中的Memory 选项卡，它将绘制 G1 的堆使用情况、实时设置、GC 暂停等。

R is a very powerful tool for the analysis of Java garbage collection log files. The primary difficulty is data cleansing so that information can be read into an R data frame. Once the data has been read into R, a rich set of tools may be used for thorough evaluation.
R 是一个非常强大的工具，用于分析 Java 垃圾收集日志文件。主要困难是数据清理，以便可以将信息读入 R 数据帧。一旦将数据读入 R，就可以使用一组丰富的工具进行彻底的评估。

HPJmeter 4.4.00.0 can read GC logs with the G1GC. Tested with the following JVM args.
HPJmeter 4.4.00.0 可以使用 G1GC 读取 GC 日志。使用以下 JVM 参数进行测试。
-XX:+UseG1GC -Xloggc:c:/temp/eRGCLogs.txt -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps
-XX:+UseG1GC -Xloggc:c:/temp/eRGCLogs.txt -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps
