公司有几癑֏�服务�?很多服务器��用了LVS,同一个应用会(x��)部��v在很多不同的服务器上,然后在上层加LVS,�q�个时�?当后��C��台或几台服务服务器宕掉了,前端应用是正常的,通过对URL的监�?不能发现问题.

上周末托��在深圳�?sh��)信的机�?有一个机�?台服务器同时断掉,�l�过查找,最后是外网交换机出��C��问题.但这个时候前端应用是正常�?而监�?没有发出报警信息,昨天在监控上面加上新功能,�I�过LVS,直接到后端服务器�q�行监控.

�q�个服务器的监控,分�ؓ(f��)两种.

1:通过SNMP�Ҏ(gu��)��务器�q�行监控.

2:通过对应用的URL�Ҏ(gu��)��务器�q�行监控.

SNMP主要监控服务器的�q�行状�?

URL监控,主要监控应用的实时运行状�?

费话��说,对应用加IP的探��代码如�?

public static Long getResponseTimeByIp(String urlAddress, String ip) {
        URL url;
        StringBuffer sb = new StringBuffer("");
        HttpURLConnection conn = null;
        Long responseTime = new Long(0);
        try {
            Long openTime = System.currentTimeMillis();
            // url = new URL("http://m.easou.com/");
            url = new URL(urlAddress);
            Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(buildInetAddress(ip), 80));
            conn = (HttpURLConnection) url.openConnection(proxy);
            conn.setConnectTimeout(50000);
            conn.setReadTimeout(50000);
            conn.setRequestMethod("GET");
            conn.setDoOutput(true);
            conn.setDoInput(true);
            BufferedReader bReader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String temp;
            boolean remaining = true;
            while (remaining) {
                temp = bReader.readLine();
                if (null != temp) {
                    sb.append(temp);
                } else {
                    remaining = false;
                }
            }
            int code = conn.getResponseCode();
            if (code == 200) {
                Long returnTime = System.currentTimeMillis();
                responseTime = returnTime - openTime;
            } else {
                responseTime = new Long("50000" + new Long(code).toString());
            }
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            responseTime = new Long("60000000");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            responseTime = new Long("60000000");
        } finally {
            if (null != conn) {
                conn.disconnect();
            }
        }
        return responseTime;
    }

使用�q�段代码,��可以对于做了负载均衡的服务�?�q�行URL的实时监控了.

发送的报警信息,�?x��)探��出目前哪台服务器的状况更�?更有针对�?方便�pȝ��l�用户处理服务器异常.
