使用check_multipath.pl检测多路径状态

检测多路径数量状态
[root@rtmp01 libexec]# ./check_multipath.pl -m 1 -o 2
OK
LUN mpathc: 2/2.
[root@rtmp01 libexec]#

执行multipath需root权限

修改NRPE配置文件
# command_prefix=/usr/bin/sudo
command_prefix=/usr/bin/sudo

修改sudoer配置文件
#Defaults    requiretty

nagios  ALL=(ALL)       NOPASSWD: ALL

保持nagios用户为可登录状态
/etc/passwd
/bin/bash
