1、监控插件介绍
通过Nagios插件check_openmanage基于DELL Openmanage Server Administrator (OMSA)，对DELL服务器硬件（物理磁盘、逻辑磁盘、电源、
电源、风扇转速、温度、CPU、内存、BIOS、Famware版本等硬件），此插件支持Win、Linux系统，
官方测试成功的DELL服务器型号：1750, 1800, 1850, 1950, 1955, 2600, 2650, 2800, 2850, 2900, 2950, 6650, 6950, 750, 850, M600, M610, R510, R610, R710, T710, R805, R815, R900, R910。
本文测试使用的R410，基本主流的DELL服务器都支持；
插件check_openmanage的依赖软件及安装过程这里省略。
关于插件详见
http://folk.uio.no/trondham/software/check_openmanage.html
监控方式本：本地插件或远程SNMP:
2、被监控机须安装DELL OMSA
2.1 安装前的设置
wget -q -O - http://linux.dell.com/repo/hardware/OMSA_6.5.3/bootstrap.cgi | bash
2.2 安装OMSA
yum install srvadmin-all -y
2.3 安装firmware-tools 用来管理BIOS和firmware版本更新
yum install dell_ft_install
yum install $(bootstrap_firmware)
2.4 更新BIOS、firmware版本
比较可用更新版本
update_firmware
安装任何可用更新
update_firmware --yes
更新后，需要重启服务器。
测试中R410报错如下（更新固件版本后才可以使用此插件获得数据）：
[root@localhost check_openmanage-3.7.5]# ./check_openmanage
Storage Error! No controllers found
Problem running 'omreport chassis memory': Error: Memory object not found
Problem running 'omreport chassis fans': Error! No fan probes found on this system.
Problem running 'omreport chassis temps': Error! No temperature probes found on this system.
Problem running 'omreport chassis volts': Error! No voltage probes found on this system.

4、Nagios监控效果
4.1 硬件监控：特定监控项（温度、cpu、内存）及所有硬件（服务器型号、SN、内存、逻辑、物理磁盘）
4.2 物理硬盘故障
4.3 更换硬盘后的监控状态
5、简单介绍OMSA平台管理服务器
这是一个基于web程序管理DELL服务器，安装完毕OMSA自动启用TCP端口1311。
访问方式：https://服务器IP：1311 ，使用系统账户密码登录，界面类似于iDrac。
功能方面:可以配置BIOS、控制电源、硬件监控、存储管理配置、软件信息、iDrac管理、系统网络管理等，功能比较强，当然是基于操作系统和OMSA。
界面（使用很方便，不再赘述）：
结束语：
服务监控固然重要，但他的载体服务器硬件监控一样不容忽视。这些功能的实现原理跟IPMI及其重要部件BMC有关。
