我们知道nmon是一款轻量级的系统占用极少，监控功能非常强大支持跨平台ARM,centos,ubuntu等等系统的工具
在sourceforge我们可以找到一个基于java编写的解析nmon监控出来的.nmon格式数据解析成报告jar包；
sourceforge地址：https://sourceforge.net/projects/jnmonanalyser/files/
由于nmon本身自带的也有Nmon Analyser，这里我不在介绍，看个人喜好，以及实际监控数据的文件结果大小，选取合适解析工具；
下面我们一起使用这个Java Nmon Analyser：
下载下来后是一个简单的jar包以及它的开发者的一个简单的readme.txt：
User‘s guide
----------------
1. Download and install nmon.
- for linux platform, you can download form: http://nmon.sourceforge.net.
- For AIX platform, you can download form : http://www.ibm.com/developerworks/wikis/display/WikiPtype/nmon , AIX 5.3 TL09+ and AIX 6.1 TL02 include nmon function within topas and its installed by default.
2. Make a pipe for nmon.
#mkfifo /tmp/nmonnamedpipe
3. Run analyser‘s agent in target host:
# java -cp nmonanal_0.1.2.jar li.xiang.nmonanalyser.agent.Agent
4. Run nmon, begin performance capture.
#nmon -s 20 -c 360 -F /tmp/nmonnamedpipe
20 second per snapshot, capture 360 snapshots, totally 2 hrs. you can put the command in crontab for long time data capture.
5. Run java nmon analyser gui.
# java -jar nmonanal_0.1.2.jar
5.1 Get the real-time performance data from agent
Main menu --> " Data Loader " --> "from agent". Input the target‘s ip address and port number(default is 8187).
5.2 Get the performance data form nmon data collection file.
Developer‘s guide.
-------------------
The interface NmonDataLoader load nmon data for analyzing, Interface NmonDataListener is observer of NmonDataLoader. It can rgister in NmonDataLoader, NmonDataLoader callback NmonDataListener, when NmonDataLoader read a nmon output line. NmonDataListener parser the nmon data and return the performance charts by getCharts().
There 2 NmonDataLoader implement : NmonFileLoader and NmonAgentLoader , NmonFileLoader load nmon data from nmon collection file. NmonAgentLoader load nmon data from agent.
There 3 NmonListener implement: CPUTagCharts, MEMTagCharts, PaginTagCharts, DiskTagCharts and NetworkCharts.
The sample load data from nmon file, and get the CPU cacategory performance charts :
NmonDataLoader loader = new NmonFileLoader("/tmp/nmonsampleoutput.nmon");
CPUTagCharts cpuCharts = new CPUTagCharts();
loader.addDataObserver(cpuCharts);
Thread loadThread = new Thread(loader);
loadThread.start();
JFreeChart[] charts = cpuCharts.getCharts();
使用也很简单直接双击jar包或者cmd执行java -jar nmonanal_0.1.3.jar 打开GUI界面选取你nmon监控生成的.nmon文件就可以了，此外它还可以支持agent模式见readme.txt,有详细介绍我就不再介绍了监控信息包含cpu,disk，NETWork,paging：
