监控dell raid卡 with nagios
制作：高进波
时间：2010-7-28
以下文档在ubuntu下制作，其他发行版的Linux基本操作一样，只是安装mpt-status和megactl会有所不同，需要进行相应修改。
服务器端配置nagios server
1.添加检测脚本
vi /usr/local/nagios/libexec/check_snmp_extend
脚本内容见check_snmp_extend.sh
修改权限
chmod +x /usr/local/nagios/libexec/check_snmp_extend
chown nagios:nagios /usr/local/nagios/libexec/check_snmp_extend
2.添加检测命令
vi /etc/nagiosql/commands.cfg
#check dell raid mpt
define command{
command_name check_snmp_extend
command_line $USER1$/check_snmp_extend $HOSTADDRESS$ $ARG1$
}
3.添加需要检测的机器
vi /etc/nagiosql/services/112.90.216.145.cfg
define service{
use generic-service
host_name 112.90.216.145
service_description RAID status
check_command check_snmp_extend!mpt-status
}
4.测试配置文件并重启nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios restart
5.命令测试获取raid状态
/usr/local/nagios/libexec/check_snmp_extend 112.90.216.145 mpt-status
注意：由于使用nagiosql来管理配置文件，路径会有所不同
客户端配置snmpd
mpt类型raid卡
1.安装mpt-status
用自己编译的deb包
wget http://gaojinbo.com/mpt.deb
dpkg -i mpt.deb
2.编写检测脚本
vi /root/raid-status.sh
#!/bin/bash
if [ -f /tmp/mpt-status ]
then
rm /tmp/mpt-status
fi
for u in 0 1 2 3
do /usr/sbin/mpt-status –autoload -s -i 2 -i $u |grep log_id |awk ‘{print $3}’ >> /tmp/mpt-status;
done
增加执行权限
chmod +x /root/raid-status.sh
3.每5分钟检测一下磁盘状态
crontab -e
*/5 * * * * /root/raid-status.sh
4.添加snmpd配置
vi /etc/snmp/snmpd.conf
extend mpt-status /bin/cat /tmp/mpt-status
or
echo "extend mpt-status /bin/cat /tmp/mpt-status" >> /etc/snmp/snmpd.conf
5.重启snmpd
/etc/init.d/snmpd restart
===================================================================
megaraid_sas类型raid卡
1.增加源
echo "deb http://hwraid.le-vert.net/debian lenny main" >> /etc/apt/sources.list
2.安装megactl
apt-get update && apt-get install megactl
3.编写检测脚本
cd
rm raid-status.sh*
wget http://gaojinbo.com/raid-status.sh
chmod +x /root/raid-status.sh
vi /root/raid-status.sh
#!/bin/bash
if [ -f /tmp/mpt-status ]
then
rm /tmp/mpt-status
fi
/usr/sbin/megasasctl |grep RAID |awk ‘{print $6}’ >> /tmp/mpt-status;
RESULT1=`/usr/sbin/megasasctl | grep bad|awk ‘{print $3}’`
RESULT2=`/usr/sbin/megasasctl | grep BAD|awk ‘{print $3}’`
if [ "$RESULT1" = "bad" -o "$RESULT2" = "BAD" ]
then
echo "DISK-BAD" >> /tmp/mpt-status;
fi
增加执行权限
chmod +x /root/raid-status.sh
4.每5分钟检测一下磁盘状态
crontab -e
*/5 * * * * /root/raid-status.sh
5.添加snmpd配置
vi /etc/snmp/snmpd.conf
extend mpt-status /bin/cat /tmp/mpt-status
or
echo "extend mpt-status /bin/cat /tmp/mpt-status" >> /etc/snmp/snmpd.conf
6.重启snmpd
/etc/init.d/snmpd restart
完成！
