以前做SA时候写的监控梭子鱼邮件网关邮件队列脚本，当队列过多的时候报警。

原理很简单，访问 http://梭子鱼网关IP或域名:8000/cgi-bin/stats.cgi ，能够得到相详细信息，然后通过shell取得需要的数据进行处理。

下面是脚本内容：

#!/bin/bash
#CompanyName City Barracuda Mail Gateway Status

    else
        #echo Can not get the file.
        echo "ERROR: Can not get stats.cgi of $1 with wget." >> ${WGET_ERROR}
        break
    fi
}

get_queue()

    QUNUE_NAME=$1
    IPADD=$2
    DESC=$3
   
    QUEUE_NUM=`grep ${QUNUE_NAME} ${STATUS_FILE} | awk -F"<|>" '{print $3}'`
    echo "${DESC} Queue: ${QUEUE_NUM}"
    if [ "${QUEUE_NUM}" -ge "${QUEUE_VALUE}" ] ; then
        echo "${IP} ${QUNUE_NAME} is more than ${QUEUE_VALUE} , please check it." >> ${WARN_INFO}
    fi
}
