邮件监控存储卷空间的脚本：
说明：
1、显示存储名、ip、卷名、total空间、free空间、1天用空间、已用百分比
2、对卷名字符数的统计（echo aa1 | wc -m）
3、对卷名部分的排除，只保留数值部分（/usr/lib64/nagios/plugins/check-netapp-ng2.pl -H 10.0.0.16 -C public -T DISKUSED -v /vol/$eNas/ -w 80 -c 90 | awk -F[:" "]+ '{print $5}' | tr -d ';' | cut -b "$Wcc-$Wf"）
4、KB转换为GB（echo $Tootal | awk '{$1/=1024*1024;printf "%.0fGB\n",$1}）
