Nagios监控打印机

Nagios以为其良好的状态检测机制，使Nagios可以利用在不同平台上的不同插件实现监控，当然它也支持使用SNMP协议（简单网络管理协议）实现各个平台和设备的监控，所以Nagios也可以使用SNMP协议来监控局域网内的打印机，Nagios监控打印机是使用check_hpjd工具调用SNMP协议来监控打印机的，在安装好的Nagios中的libexec插件目录下可能没有，是因为服务器上没有安装SNMP协议相关的依赖包net-snmp和net-snmp-utils，所以可以直接用yum或者是apt安装下，再重新编译下nagios-plugins，有一点像Nagios没有安装MySQL时没有check_mysql一样，操作如下：

[iyunv@localhost nagios-plugins-2.2.1]# yum -y install net-snmp net-snmp-utils
[iyunv@localhost nagios-plugins-2.2.1]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
[iyunv@localhost nagios-plugins-2.2.1]# make && make install

此时再看libexec插件目录下就有check_hpjd插件，打印机的监控方式有点类似于Nagios监控Windows上的NSClient++，可以参看http://jim123.blog.51cto.com/4763600/1956790，在Nagios配置好后就有打印的配置模板，同NSClient++中一样修改下模板:

配置好后重启Nagios后就可以实现打印机的监控 wKiom1mVZoyi4kMqAAAau-PMe94393.png-wh_500x0-wm_3-wmp_4-s_483796998.png
