nagios监控NFS是否被正确的挂载

脚本名称：check_nfsmount
脚本作用： 
    1，检查NFS磁盘是否被挂载 
    2，报告哪些NFS没有被挂载
使用方法： 
    1，将需要mount的NFS磁盘写入到fstab，如下
# cat /etc/fstab
/dev/VolGroup00/LogVol00 /                       ext3    defaults,usrquota,grpquota        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0
192.168.211.129:/home/tst       /data/tst       nfs     defaults        0 0
192.168.211.129:/home/tst02     /data/tst02     nfs     defaults        0 0
192.168.211.129:/home/tst03     /data/tst03     nfs     defaults        0 0
    2，将脚本nagios安装目录的libexec下，并赋予可执行权限
    3，配置nrpe配置文件，添加相应的command
    4，nagios监控机上添加相应的服务

}

    for list in $NFSFSTAB
    do

        if [ -z "${NFS_MOUNT}" ];then
            LIST="$LIST$list "
        fi
    done
}
if [ -n "${NFSMTAB}" ];then
    CHECK_MOUNT
    if [ -z "${LIST}" ];then
            RESULT="$CHECKNAME OK - NFS BE MOUNTED PROPERLY"
            EXIT_STATUS=$STATE_OK
    else
