我如何使用check_nt命令而不是使用百分比值检查Nagios中的确切空间量（MB或GB）？

check_nt!USEDDISKSPACE返回磁盘使用的大小和百分比。 但是，门槛是百分比。

如果您希望根据大小接收警报，则可以为check_nt命令编写包装程序脚本，例如check_disk_by_size ：

 #!/bin/bash FREESPACE=`/usr/local/nagios/libexec/check_nt -H $2 -p 12489 -s pa$$word \ -v USEDDISKSPACE -l $4 | awk -F"- " '{ print $4 }' | awk -F "|" '{ print $1 }'` SIZE=`echo $FREESPACE | awk '{ print $2 }'` UNIT=`echo $FREESPACE | awk '{ print $3 }'` if [ $UNIT == "Gb" ]; then SIZE=`echo $SIZE \* 1024 | bc` fi if [ `echo "$SIZE >= $6" | bc` -eq 1 ]; then echo "$4:\_Drive_Space OK - $FREESPACE" exit 0 elif [ `echo "$SIZE < $6" | bc` -eq 1 -a `echo "$SIZE > $8" | bc` -eq 1 ]; then echo "$4:\_Drive_Space WARNING - $FREESPACE" exit 1 elif [ `echo "$SIZE <= $8" | bc` -eq 1 ]; then echo "$4:\_Drive_Space CRITICAL - $FREESPACE" exit 2 fi 

testing：

 $ check_disk_by_size.sh -H 192.168.6.31 -lc -w 10240 -c 5120 c:\_Drive_Space OK - free 13.01 Gb (36%) $ check_disk_by_size.sh -H 192.168.6.31 -lc -w 14240 -c 5120 c:\_Drive_Space WARNING - free 13.01 Gb (36%) $ check_disk_by_size.sh -H 192.168.6.31 -lc -w 16240 -c 15120 c:\_Drive_Space CRITICAL - free 13.01 Gb (36%) 

你可以像这样将它添加到Nagios：

 "check_disk_by_size.sh". # 'check_disk_by_size' command definition define command{ command_name check_disk_by_size command_line $USER1$/check_disk_by_size.sh -H $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$ } define service{ use generic-service host_name fileserver1 service_description Drive Space fileserver1: L: check_command check_disk_by_size!-l L -w 4096 -c 2048 notifications_enabled 1 } 

我修改了代码以适应新的BASH语法和更强大的检查。

 shift $（（OPTIND-1））

如果[[-z“$ HOST_NAME”]] ||  [[-z“$ PORT”]] ||  [[-z“$ DISC”]] ||  [[-z“$ WARN_THRESHOLD”]] ||  [[-z“$ CRITICAL_THRESHOLD”]]; 然后
    用法

 FREESPACE =`/ usr / local / nagios / libexec / check_nt -H $ HOST_NAME -p $ PORT \
 -v USEDDISKSPACE -l $ DISC |  awk -F“ - ”“{print $ 4}”|  awk -F“|”  '{print $ 1}'

 SIZE =`echo $ FREESPACE |  awk'{print $ 2}'`
 UNIT =`echo $ FREESPACE |  awk'{print $ 3}'`

如果[[$ UNIT ==“Gb”]];那么
     SIZE =`echo $ SIZE \ * 1024 |  bc`
科幻

如果[[``echo“$ SIZE> = $ WARN_THRESHOLD”|  bc` -eq 1]];然后
     echo“$ DISC：\ _ Drive_Space OK  -  $ FREESPACE”
    退出0
 elif [[``echo“$ SIZE $ CRITICAL_THRESHOLD”|  bc` -eq 1]];然后
    回声“$ DISC：\ _ Drive_Space警告 -  $ FREESPACE”
    出口1
 elif [[``echo“$ SIZE 

我修改了Gnought的脚本，这是对Quanta脚本的修改，甚至进一步删除了一些代码错误，并修改了结果，使其更接近于check_nt的原始输出，从而在分析趋势随着时间的推移以及性能数据被加回时提供了更好的数据在。
