Identify and diagnose performance problems in Java applications running on HP-UX or on NonStop servers
Improve garbage collection performance
Analyze Java heap dumps
Monitor live Java applications and analyze profiling data
Capture extended profiling data with zero preparation when using JDK/JRE 5.0.04 or later
Capture detailed garbage collection data with zero preparation when using JDK/JRE 5.0.14 or later or JDK/JRE 6.0.02 or later or JDK/JRE 7.0.00 or later
Run the HPjmeter console on HP-UX, Linux, and Windows systems
貌似只能打开由以下参数生成的GC log， -verbose:gc -Xloggc:gc.log,添加其他参数生成的gc.log无法打开。
jvisualvm还可以heapdump出对应hprof文件（默认存放路径：监控的服务器 /tmp下），利用HPjmeter可以对其进行分析
