监控项目---流量控制模块

监控项目---流量控制模块

  流量控制模块相对于其它模块功能稍多,具体参数有:

    alarm_traffic_in_up 10  入流量上限报警阀值
    alarm_traffic_out_below 30  出流量下限报警阀值
    alarm_traffic_out_up 80  出流量上限报警阀值
    alarm_traffic_out_time_below 10 22  入流量上线报警时间区间
    alarm_traffic_times 3  流量报警次数

  流量取值即以IP为目录下的in out文件,由中心服务器取各服务器串值得出..脚本名为:

    Module_Traffic_Alarm.sh  内容如下:

      注:参数配置优先为各IP目录下alarm_conf目录下的个性参数配置,以参数名为文件名,内存参数值..默认配置为default.conf存所有参数默认值...每行二列分别为参数名,参数值...

      当连续到达报警次数后,脚本会启动报邮件/短信报警程序,即alarm.sh.由报警程序根据送来的报警串来选择报警优先级,及相关处理人..报警程序后文将介绍...
