logstash日志收集分析系统
Logstash provides a powerful pipeline for storing, querying, and analyzing your logs. When using Elasticsearch as a backend data store and Kibana as a frontend reporting tool, Logstash acts as the workhorse. It includes an arsenal of built-in inputs, filters, codecs, and outputs, enabling you to harness some powerful functionality with a small amount of effort.
http://semicomplete.com/files/logstash/ logstash收集日志，需要java平台
logstash-1.4.2.tar.tar jdk-7u67-linux-x64.rpm
http://www.elasticsearch.org/overview/elkdownloads elasticsearch搜索引擎，此页面有帮助文档
http://www.elasticsearch.org/overview/kibana/installation/ Kibana提供web界面

#上面已经很清楚的说明了logstash的工作模式，下面就结合kibaba在页面查看
#kibaba，在logstash里面已经集成了kibaba，在vendor/kibana/这个目录里面，当然你也可以下载 kibana-3.1.2.zip 然后解压
