nagios利用NRPE监控CPU、负载、磁盘IO

1、nagios 利用 NRPE 监控 CPU、负载、磁盘IO1.在监控机上安装NRPEtar -zxvf nrpe-2.12.tar.gzcd nrpe-2.12./configuremake allmake install-plugin2.在被监控机上安装nagios 插件和 NRPE(1). 先增加 nagios 用户：useradd nagios (2.)安装 nagios 插件：tar -zxvf nagios-plugins-1.4.14.tar.gzcd nagios-plugins-1.4.14./configure -prefix=/usr/local/nagiosmakemak

2、e install (3). 安装 nrpe：tar -zxvf nrpe-2.12.tar.gzcd nrpe-2.12./configure -prefix=/usr/local/nagiosmake allmake install-pluginmake install-daemonmake install-daemon-configmake install-xinetd nrpe 安装为 xinetd 服务(4). 编辑 nrpe 配置文件，增加监控机地址：#vi /etc/xinetd.d/nrpeonly_from = 127.0.0.1 10.1.1.14 (5). 修改 serv

3、ices 文件，增加端口#vi /etc/servicesnrpe 5666/tcp #NRPE (6). 重启 xinetd 服务 service xinetd restart (7). 查看服务是否启动 #/usr/local/nagios/libexec/check_nrpe -H localhost NRPE v2.12如果出现Connection refused by host 需要安装 yum intallopenssl*至此被监控机上的操作就结束了，如果有需要增加监控项，需修改 /etc/xinetd.d/nrpe 文件。3.修改监控机上commands.cfg 文件，增加che

4、ck_nrpe 的定义：define commandcommand_name check_nrpecommand_line $USER1$/check_nrpe -H$HOSTADDRESS$ -c $ARG1$ 4. 在监控机上测试与被监控机的通讯是否正常：roottest1 objects# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_loadOK - load average: 0.05, 0.06,0.00|load1=0.050;15.000;30.000;0;load5=0.060;10.000;25.000

5、;0; load15=0.000;5.000;20.000;0;能够正常获取信息。vim /usr/local/nagios/etc/nrpe.cfg修改allowed_hosts=127.0.0.1,10.1.1.14( 监控机 ) 增加commandcheck_sda2=/usr/local/nagios/libexec/check_disk-w 20% -c 10% -p /dev/sda2 - 意思是监控第二个分区commandcheck_swap=/usr/local/nagios/libexec/check_swap-w 20% -c 10% - 监控内存修改监控机的service

6、s.cfg 增加需要监控的服务5.修改服务配置文件：增加：define service host_name 1.1.1.1max_check_attempts 5check_period 24x7notification_interval 10normal_check_interval 1retry_check_interval 1service_description checkdisk2check_command check_nrpe!check_sda2 #监控第二个硬盘notification_period 24x7notification_options w,u,c,rcontact
