通过80端口访问的池的节点的里的java容器的健康检测。
 
本地的java容器提供了8019和7777两个端口的服务。(这里就要求需要检测80,8019,7777三个端口的服务都是好的)
 
 apache下的rewrite有如下的定义:
       RewriteRule /(\S+)\.jsp$ ajp://127.0.0.1:8019/$1\.jsp [P]
 
 
所以就可以添加8019端口的服务下的jsp内容如下(如果7777端口下的jsp返回ok则这个jsp也返回ok。):
<%@ page language="java" contentType="text/html; charset=UTF-8" %>



< %@page import="java.io.InputStream"%>
< %@page import="java.io.DataInputStream"%>

<%
        boolean heartbeat=false;
        Log log = LogFactory.getLogger(this.getClass());
        String path = " http://xxxxxxxxxx:7777/xxxxxxxxx.jsp";
        URL url = new URL(path);
        try {
                HttpURLConnection conn = (HttpURLConnection)url.openConnection();
                InputStream in = conn.getInputStream();
                DataInputStream dis = new DataInputStream(in);
                int i = 0;
                byte[] bye =new byte[10];
                String msg = "";
                while((i = dis.read(bye)) > 0){
                        msg = new String(bye);
                }
                if("ok".equals(msg.trim())){
                        heartbeat=true;
                }
                log.info("==I am ok!==");
        } catch (Exception e){
        } finally {
        }
        if (!heartbeat) {
%>
error
<%
} else {
%>
ok
<%
}
%>
 
 
在f5的local traffic下的monitor里面创建。在seng string里面定义
GET /TomcatServerMonitor.jsp
Receive String里面定义
ok
然后在池的health monitor里面加上这个检测。
