nagios牛人进..

TopOne_

我想写个脚本监控raid卡的
脚本如下
#!/bin/bash
d=`/usr/sbin/megasasctl | grep 'RAID' | grep  'optimal'`
dd=`/usr/sbin/megasasctl | grep 'RAID' | grep -v 'optimal'`
if [ "$ddd" != "optimal" ]
then
echo "$dd"
fi
a=`/usr/sbin/megasasctl | grep  'a0e' |grep -v 'online' | egrep  -v "hotspare|hot spares"`
if [ -n "$a" ]
then
echo "$a"
fi


我想把它变成一个nagios可调用的 正常返回OK不正常返回$a,$dd  那个什么w,c,o的怎么写进去让nagios调用……
期待解答。。

我之前写的监控脚本，，通过exit返回值来判断告警级别，分别是
3 Unknown
2 Critical
1 Warning
0 OK
具体数值可以通过print类似函数的输出，具体格式就是：
    你期望的输出 | 监控项=当前值;Warning阀值；Critical阀值
其中 Warning阀值和Critical阀值可以通过外部输入获得。

具体的规则，可以看nagios的官方手册中的 Nagios Plugin API 一节。说得很详细。。
