监控系统nagios+nconf+pnp4

rgfwwq

                      配置Nconf管理NAGIOS更简单且效率更高
  
  参照上一篇NAGIOS之SNMP方式监控系统的博文,安装好LAMP环境和NAGIOS.
  
  一.本文的案例所需软件
  nconf-1.2.6-0.tgz
  pnp4nagios-0.6.18.tar.gz
  NSCLIENT++
  cgilib-0.6.tar.gz
  rrdtool
  pnp4nagios-0.6.7.tar.gz
  
  二.安装nconf
  1.解压安装包
  tar -xf nconf-1.2.6-0.tgz -C /var/www/html/
  2.配置nconf所需的数据库级授权用户
  mysql> CREATE DATABASE nconf;   
Query OK, 1 row affected (0.01 sec)
  mysql> GRANT ALL ON nconf.* TO 'nconf'@'localhost' IDENTIFIED BY 'nconf';   
Query OK, 0 rows affected (0.00 sec)
  mysql> FLUSH PRIVILEGES;   
Query OK, 0 rows affected (0.00 sec)
  3.修改目录用户权限
  chown -R apache.apache config/ temp/ static_cfg/ output/
  4.访问nconf http://ip/nconf
  
  
  
  
  
  
  …………
  5.按照需求删除以安装文件
  6.测试登录
  
  二.配置NCONF
  1.无法连接数据库
  
  2.配置NCONF链接数据库及执行脚本
  ln -s /usr/local/nagios/bin/nagios bin/nagios   
chmod +x /var/www/html/nconf/bin/generate_config.pl  
chown -R apache.apache bin/     
chmod +x /usr/local/nagios/bin/nagios     
chmod +x /var/www/html/nconf/ADD-ONS/deploy_local.sh
  vim /var/www/html/nconf/ADD-ONS/deploy_local.sh //根据环境修改里面的nagios路径,此处无需修改
  
  
  3.执行脚本,在/usr/local/nagios/etc/下生成两个目录Default_collector 与global 用于存放通用nconf定义的监控资源
  cd ADD-ONS/   
./deploy_local.sh     
Running configuration check...done.     
Reloading nagios configuration...done
  4.添加至crontab中让其每隔一分钟执行一次
  */1 * * * *  /bin/sh /var/www/html/nconf/ADD-ONS/deploy_local.sh
  
  5.修改nagios.cfg配置文件加注释,添加如下两行
  vim /usr/local/nagios/etc/nagios.cfg
  
  
  6.重启Nagios
  
  7.以上Nconf 配置完成,安装客户端手动添加监控资源测试
  8.在被监控机上安装Windows客户端.
  
  9.配置ini文件填入nagios地址,后重启客户端
  
  10.添加监控资源
  
  
  
  
  
  11.此处省略只列出各属性的参数值
  CPU
  
  Memory
  
  12.自定义端口
  
  13.配置邮件告警,将等三方程序sendEmail 传入监控机 并添加执行权限(用法请参考上一篇NAGIOS之SNMP监控的博文,这里不再赘述)
  
  14.分别填入以下内容
  
  /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/local/bin/sendEmail -f xxx@xxx.com -t $CONTACTEMAIL$ -s 1.1.1.1 -u "** $NOTIFICATIONTYPE$ Address: $HOSTADDRESS$ is $HOSTSTATE$ **"
  /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/local/bin/sendEmail -f xxx@xxx.com -t $CONTACTEMAIL$ -s 1.1.1.1 -u "** $NOTIFICATIONTYPE$ Address:$HOSTADDRESS$ ServiceAlert:$SERVICEDESC$ is $SERVICESTATE$ **"
  15.测试邮件通知功能,这里先定义参数值为20 警告,30严重 (邮件通知有点延迟)
  
  
  
    三.安装PNP4NAGIOS
  1.安装cgilib
  tar -zxvf cgilib-0.6.tar.gz
  cd cgilib-0.6
  make
  cp aux.h /usr/include/
  cp cgi.h /usr/include/
  cp libcgi.a /usr/lib/
  2.安装rrdtool
  yum –y localinstall rrdtool-*
  
  3.安装pnp4nagios
  cd /usr/lib/perl5/5.8.8/i386-linux-thread-multi
  cp /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/RRDs.pm /usr/lib/perl5/5.8.8/i386-linux-thread-multi/
  测试: perl -MRRDs -le 'print q(ok!)'
  注:以上步骤采用rpm包安装rrdtool时请忽略
  tar -zxvf pnp4nagios-0.6.18.tar.gz
  cd pnp4nagios-0.6.18/
  ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/bin/rrdtool --with-perfdata-dir=/usr/local/nagios/share/perfdata
  make;make all
  make install
  make install-webconf(可不装)
  make install-config
  make install-init(可不装)
  (make fullinstall－本命令安装上述所有步骤)
  4.配置apache
  vi /etc/httpd/conf/httpd.conf
  末尾添加如下信息
  Alias /pnp4nagios "/usr/local/pnp4nagios/share"
  <Directory "/usr/local/pnp4nagios/share">
  AllowOverride None
  Order allow,deny
  Allow from all
  AuthName "Nagios Access"
  AuthType Basic
  AuthUserFile /usr/local/nagios/etc/htpasswd.user
  Require valid-user
  <IfModule mod_rewrite.c>
  RewriteEngine On
  Options FollowSymLinks
  RewriteBase /pnp4nagios/
  RewriteRule ^(application|modules|system) - [F,L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule .* index.php/$0 [PT,L]
  </IfModule>
  </Directory>
  保存后重启apache服务: service httpd restart
  http://192.168.1.109/pnp4nagios/index.php
  
  rm -rf /usr/local/pnp4nagios/share/install.php
  
  5.配置NCONF支持PNP
  
  
  6.填入以下内容
  /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
  
  
  7.填入以下内容
  /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$'class='tips'rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$
  
  8.分别真入以下内容
  process-host-perfdata
  /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d  HOSTPERFDATA
  
  process-service-perfdata
  /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d  HOSTPERFDATA
  
  9.创建host-pnp 及srv-php 模板
  
  
  10.分别选择上面定义的action_url,执行测试配置文件选项无报错稍后即可出图
