用Nagios监控Dell服务器硬件状况(snmp)

Dell有一套监控硬件的软件，Linux/windows都可以监控。官方网址：http://linux.dell.com/repo/hardware/安装方法（centos linux 5.7 x64）：被监控服务器：1) 增加dell的yum库wget -q -O - http://linux.dell.com/repo/hardware/OMSA_6.5.2/bootstrap.cgi | bash
2) 安装srvadmin
Installing OpenManage Server Administrator
yum install srvadmin-all
3)安装firmware-tools，这个也可以不装，升级bios这类的用的。
Installing firmware-tools to manage BIOS and firmware updates
yum install dell_ft_install
4) 启动srvadmin：/opt/dell/srvadmin/sbin/srvadmin-services.sh start可以把上面的命令加入/etc/rc.local内开机启动。
5) 重启snmpd(假定您已经配置好了snmpd):service snmpd restart
监控端：1）安装perl的库:
yum install perl-Net-SNMP perl-Config-Tiny perl-Crypt-Rijndael
2) 安装nagios插件openmanage(需先配置好nagios server):
wget http://folk.uio.no/trondham/software/files/nagios-plugins-openmanage-3.7.3-1.el5.x86_64.rpm 3) 修改配置文件：
vim /etc/nagios/objects/commands.cfg
define command {
command_name check_openmanage
command_line /usr/lib64/nagios/plugins/check_openmanage -H $HOSTADDRESS$
}

vim /etc/nagios/objects/hosts.cfg
define service{
use generic-service ; Name of service template to use
hostgroup_name all_servers
service_description Dell OMSA
check_command check_openmanage
normal_check_interval 10
}
4) 重启nagiosservice nagios reload
完成。
也可以手工用脚本调试：[root@web ~]# /usr/lib64/nagios/plugins/check_openmanage -H 192.168.2.4
OK - System: 'PowerEdge R510 II', SN: 'XXXXXXX', 48 GB ram (6 dimms), 2 logical drives, 8 physical drives
如果报错：
SNMP CRITICAL: No response from remote host '10.1.2.3'或： ERROR: (SNMP) OpenManage is not installed or is not working correctly
首先确认/etc/snmpd.conf内是否有以下这行：# Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX
smuxpeer .1.3.6.1.4.1.674.10892.1一般安装srvadmin的时候会自动加上的，如果没找到手工加上。再检查被监控端的服务器上是否有启动snmpd和srvadmin，没有的话启动起来：service snmpd restart/opt/dell/srvadmin/sbin/srvadmin-services.sh restart
