nagios利用NRPE監(jiān)控CPU、負載、磁盤IO

1、nagios 利用 NRPE 監(jiān)控 CPU、負載、磁盤IO1.在監(jiān)控機上安裝NRPEtar -zxvf nrpe-2.12.tar.gzcd nrpe-2.12./configuremake allmake install-plugin2.在被監(jiān)控機上安裝nagios 插件和 NRPE(1). 先增加 nagios 用戶：useradd nagios (2.)安裝 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). 安裝 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 安裝為 xinetd 服務(wù)(4). 編輯 nrpe 配置文件，增加監(jiān)控機地址：#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). 重啟 xinetd 服務(wù) service xinetd restart (7). 查看服務(wù)是否啟動 #/usr/local/nagios/libexec/check_nrpe -H localhost NRPE v2.12如果出現(xiàn)Connection refused by host 需要安裝 yum intallopenssl*至此被監(jiān)控機上的操作就結(jié)束了，如果有需要增加監(jiān)控項，需修改 /etc/xinetd.d/nrpe 文件。3.修改監(jiān)控機上commands.cfg 文件，增加che

4、ck_nrpe 的定義：define commandcommand_name check_nrpecommand_line $USER1$/check_nrpe -H$HOSTADDRESS$ -c $ARG1$ 4. 在監(jiān)控機上測試與被監(jiān)控機的通訊是否正常：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;能夠正常獲取信息。vim /usr/local/nagios/etc/nrpe.cfg修改allowed_hosts=127.0.0.1,10.1.1.14( 監(jiān)控機 ) 增加commandcheck_sda2=/usr/local/nagios/libexec/check_disk-w 20% -c 10% -p /dev/sda2 - 意思是監(jiān)控第二個分區(qū)commandcheck_swap=/usr/local/nagios/libexec/check_swap-w 20% -c 10% - 監(jiān)控內(nèi)存修改監(jiān)控機的service

6、s.cfg 增加需要監(jiān)控的服務(wù)5.修改服務(wù)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 #監(jiān)控第二個硬盤notification_period 24x7notification_options w,u,c,rcontact
