实时监控DNS状态，并向MQ发送消息

2012-10-16

实现：实时监控DNS状态，一旦发现DNS域名故障或DNS域名第一次恢复正常，即向ActiveMQ中发送消息。

监控实体：

package com.syxp.dns.entity;

public class Alarm {

	/**
	 * 告警实体to MQ status: dns状态1正常0故障 instatu: 记录是否入库,1入库，0不入库
	 */

	private int status; // 监控状态 1为正常，0为故障
	private int instatu; // 入库状态 1为需要入库，0为不需要入库
	private String alarmtype; // 告警类型
	private String alarmaddress; // 告警设备地址
	private String alarmcontent; // 告警内容
	private String alarmoccurtime; // 告警发生时间
	private int monitorstatus; // 监控状态
	private String sms; // 短信提醒
	private String phone; // 手机号
	private String alarmdevname; // 告警对象名称

	public String getSms() {
		return sms;
	}

	public void setSms(String sms) {
		this.sms = sms;
	}

	public String getPhone() {
		return phone;
	}

	public void setPhone(String phone) {
		this.phone = phone;
	}

	public int getMonitorstatus() {
		return monitorstatus;
	}

	public void setMonitorstatus(int monitorstatus) {
		this.monitorstatus = monitorstatus;
	}

	public String getAlarmtype() {
		return alarmtype;
	}

	public void setAlarmtype(String alarmtype) {
		this.alarmtype = alarmtype;
	}

	public String getAlarmaddress() {
		return alarmaddress;
	}

	public void setAlarmaddress(String alarmaddress) {
		this.alarmaddress = alarmaddress;
	}

	public String getAlarmcontent() {
		return alarmcontent;
	}

	public void setAlarmcontent(String alarmcontent) {
		this.alarmcontent = alarmcontent;
	}

	public String getAlarmoccurtime() {
		return alarmoccurtime;
	}

	public void setAlarmoccurtime(String alarmoccurtime) {
		this.alarmoccurtime = alarmoccurtime;
	}

	public String getAlarmdevname() {
		return alarmdevname;
	}

	public void setAlarmdevname(String alarmdevname) {
		this.alarmdevname = alarmdevname;
	}

	public int getStatus() {
		return status;
	}

	public void setStatus(int status) {
		this.status = status;
	}

	public int getInstatu() {
		return instatu;
	}

	public void setInstatu(int instatu) {
		this.instatu = instatu;
	}
}
