2. Nagios安装

1. 功能介绍

1. 监控网络服务（SMTP、POP3、HTTP、NNTP、PING等）；​
2. 监控主机资源（处理器负荷、磁盘利用率等）；​
3. 简单地插件设计使得用户可以方便地扩展自己服务的检测方法；​
4. 并行服务检查机制；​
5. 具备定义​​网络分层​​结构的能力，用"parent"主机定义来表达网络主机间的关系，这种关系可被用来发现和明晰主机宕机或不可达状态；​
6. 当服务或​​主机​​问题产生与解决时将告警发送给联系人（通过EMail、短信、用户定义方式）；​
7. 可以定义一些处理程序，使之能够在服务或者​​主机​​发生故障时起到预防作用；​
8. 自动的日志滚动功能；​
9. 可以支持并实现对​​主机​​的​​冗余​​监控；​
10. 可选的WEB界面用于查看当前的网络状态、通知和故障历史、日志文件等。​

2. 基础包安装

1. 安装依赖包​[root@nagios-server opt]# yum -y install gcc glibc glibc-common gd gd-devel gd-devel openssl-devel libxml2-devel xinetd.d​
2. 创建用户​

[root@nagios-server opt]# useradd nagios​

[root@nagios-server opt]# mkdir -p /usr/local/nagios​

[root@nagios-server opt]# chown -R nagios.nagios /usr/local/nagios/​

1. 安装Nagios

1. 源码安装​[root@nagios-server opt]# tar zxvf nagios-3.4.3.tar.gz​
   [root@nagios-server opt]# cd nagios​
   [root@nagios-server nagios]# ./configure --prefix=/usr/local/nagios/​
   [root@nagios-server nagios]# make all​
   [root@nagios-server nagios]# make install​
   [root@nagios-server nagios]# make install-init 设置系统服务​
   [root@nagios-server nagios]# make install-commandmode #设置权限​
   [root@nagios-server nagios]# make install-config #安装示例程序​
   # /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg //检查配置文件的正确性​
2. 启动服务​[root@~]#/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg ​
   [root@~]#/etc/init.d/nagios start​
3. 添加自启动​

[root@nagios-server nagios]# chkconfig --add nagios​

[root@nagios-server nagios]# chkconfig --level 35 nagios on​

[root@nagios-server nagios]# chkconfig --list nagios​

nagios 0:off 1:off 2:off 3:on 4:on 5:on 6:off​

1. 安装Apache

1. 卸载自带apache​[root@nagios-server nagios]# rpm -qa|grep httpd​
   httpd-2.2.3-63.el5.centos​
   httpd-manual-2.2.3-63.el5.centos​
   system-config-httpd-1.3.3.3-1.el5​
   [root@nagios-server nagios]# rpm -e httpd-2.2.3-63.el5.centos --nodeps​
2. 源码安装​[root@nagios-server opt]#tar zxvf httpd-2.2.23.tar.gz​
   [root@nagios-server opt]# cd httpd-2.2.23​
   [root@nagios-server httpd-2.2.23]# ./configure --prefix=/usr/local/apache2​
   [root@nagios-server httpd-2.2.23]# make && make install​
3. 启动apache：​vi /usr/local/apache2/conf/httpd.cnf​
   在#ServerName ​​www.example.com:80​​下面添加这一行：​
   ServerName localhost:80​
   [root@nagios-server bin]# /usr/local/apache2/bin/apachectl start​
4. ​​将Apache添加为Linux的系统服务 实现自启动 ​​​

[root@nagios-server ~]#cp /usr/local/apache2/bin/apachectl /etc/rc.d/init.d/httpd
[root@nagios-server ~]#ln -s /etc/rc.d/init.d/httpd /etc/rc.d/rc3.d/S61httpd​

[root@nagios-server ~]#ln -s /etc/rc.d/init.d/httpd /etc/rc.d/rc5.d/S61httpd​

编辑vi /etc/rc.d/init.d/httpd，在第2行添加如下信息：​

# chkconfig: 35 61 61
# description: Apache​

[root@nagios-server ~]#chkconfig --add httpd​

1. 安装PHP

1. 源码安装​

报错：​

# yum -y install perl-devel​

# yum -y install sqlite-devel​

[root@nagios-server opt]# tar zxvf php-5.4.10.tar.gz​

[root@nagios-server opt]# cd php-5.4.10​

#./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs​

[root@nagios-server php-5.4.10]# make &&make install​

1. 整合Apache

1. 修改运行httpd服务用户的组​vi /usr/local/apache2/conf/httpd.conf​
   User daemon ​
   Group daemon ​
   修改为​
   User nagios ​
   Group nagios ​
2. 配置apache解析php后缀名使用 PHP 解析​编辑/usr/local/apache2/conf/httpd.conf文件​
   166| ​
   <IfModule dir_module> ​
   DirectoryIndex index.html ​
   </IfModule> ​
   修改为​
   <IfModule dir_module> ​
   DirectoryIndex index.html index.php ​
   </IfModule> ​
   添加：​
   AddType application/x-compress .Z​
   AddType application/x-gzip .gz .tgz​
   AddType application/x-httpd-php.php .phtml​
4. 测试​/usr/local/apache2/htdocs目录下，新建test.php文件，添加一下内容​
   <?php​
   phpinfo();​
   ?>​
   浏览器访问该地址：​​http://ip/test.php​​​



5. 
   
6. 添加nagios的web监控页面的验证配置​vi /usr/local/apache2/conf/httpd.conf 添加如下代码​
   #setting for nagios ​
   ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin" //55行 ​
   <Directory "/usr/local/nagios/sbin"> ​
   AuthType Basic ​
   Options ExecCGI ​
   AllowOverride None ​
   Order allow,deny ​
   Allow from all ​
   AuthName "Nagios Access" ​
   AuthUserFile /usr/local/nagios/etc/htpasswd ​
   Require valid-user ​
   </Directory> ​
   Alias /nagios "/usr/local/nagios/share" ​
   <Directory "/usr/local/nagios/share"> ​
   AuthType Basic ​
   Options None ​
   AllowOverride None ​
   Order allow,deny ​
   Allow from all ​
   AuthName "nagios Access" ​
   AuthUserFile /usr/local/nagios/etc/htpasswd // 用于此目录访问身份验证的文件​
   Require valid-user ​
   </Directory>​
7. 创建apache目录验证文件​

[root@nagios-server conf]# /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd zrsf 用户名​

New password: ​

Re-type new password: ​

Adding password for user zrsf​

1. 汉化步骤

1. 安装汉化包（可选择）​

[root@nagios-server opt]# tar -jxvf nagios-cn-3.2.3.tar.bz2​

[root@nagios-server opt]# cd nagios-cn-3.2.3​

[root@nagios-server nagios-cn-3.2.3]# ./configure --prefix=/usr/local/nagios/ --with-command-group=nagios​

[root@nagios-server nagios-cn-3.2.3]# make all​

[root@nagios-server nagios-cn-3.2.3]# make install​

[root@nagios-server nagios-cn-3.2.3]# make install-init​

[root@nagios-server nagios-cn-3.2.3]# make install-commandmode​

[root@nagios-server nagios-cn-3.2.3]# make install-config​

[root@nagios-server nagios-cn-3.2.3]# make install-webconf​

可直接安装汉化包，或者安装汉化插件。（若已安装nagios，再安装汉化包原配置文件会被覆盖）​

1. 安装插件

1. 安装nagios-plugin，可监控本身​# tar zxvf nagios-plugins-1.4.16.tar.gz​
   # cd nagios-plugins-1.4.16​
   # ./configure --prefix=/usr/local/nagios​
   # make && make install​
2. 安装check-nrpe​

# tar zxvf nrpe-2.13.tar.gz​

# cd nrpe-2.13​

# ./configure --prefix=/usr/local/nagios​

# make all​

# make install-plugin​

1. 配置文件Nagios 安装完毕后，默认的配置文件在/usr/local/nagios/etc目录下：
   # ls /usr/local/nagios/etc/
   cgi.cfg nagios.cfg objects resource.cfg statuswrl.cgi
   hosts.cfg nagiosgraph.cfg
   # ls /usr/local/nagios/etc/objects
   commands.cfg localhost.cfg switch.cfg timeperiods.cfg
   contacts.cfg printer.cfg templates.cfg windows.cfg
   每个文件或目录含义如下表所示：

1. 配置文件关系​在nagios的配置过程中涉及到的几个定义有：主机、主机组，服务、服务组，联系人、联系人组，监控时间，监控命令等，从这些定义可以看出，nagios各个配置文件之间是互为关联，彼此引用的。​
   成功配置出一台nagios监控系统，必须要弄清楚每个配置文件之间依赖与被依赖的关系，最重要的有四点：​
   第一：定义监控哪些主机、主机组、服务和服务组；​
   第二：定义这个监控要用什么命令实现；​
   第三：定义监控的时间段；​
   第四：定义主机或服务出现问题时要通知的联系人和联系人组。​
2. 配置Nagios为维护方便，建议将nagios各个定义对象创建独立的配置文件：

• 创建/usr/local/nagios/etc/hosts.cfg文件来定义主机和主机组​
• 创建/usr/local/nagios/etc/service/centos.cfg weblogic.cfg oracle.cfg文件来定义服务​
• 用默认的contacts.cfg文件来定义联系人和联系人组​
• 用默认的commands.cfg文件来定义命令​
• 用默认的timeperiods.cfg来定义监控时间段​
• 用默认的templates.cfg文件作为资源引用文件​

1. templates.cfg文件​nagios主要用于监控主机资源以及服务，在nagios配置中称为对象，为了不必重复定义一些监控对象，Nagios引入了一个模板配置文件，将一些共性的属性定义成模板，以便于多次引用。这就是templates.cfg的作用.详细介绍下templates.cfg文件中每个参数的含义：​
   define contact{​
   name generic-contact ; 联系人名称​
   service_notification_period 24x7 ; 当服务出现异常时，发送通知的时间段，这个时间段"24x7"在timeperiods.cfg文件中定义​
   host_notification_period 24x7 ; 当主机出现异常时，发送通知的时间段，这个时间段"24x7"在timeperiods.cfg文件中定义​
   service_notification_options w,u,c,r ; 这个定义的是“通知可以被发出的情况”。w即warn，表示警告状态，u即unknown，表示不明状态;​
   ; c即criticle，表示紧急状态，r即recover，表示恢复状态;​
   ; 也就是在服务出现警告状态、未知状态、紧急状态和重新恢复状态时都发送通知给使用者。​
   host_notification_options d,u,r ; 定义主机在什么状态下需要发送通知给使用者，d即down，表示宕机状态;​
   ; u即unreachable，表示不可到达状态，r即recovery，表示重新恢复状态。​
   service_notification_commands notify-service-by-email ; 服务故障时，发送通知的方式，可以是邮件和短信，这里发送的方式是邮件;​
   ; 其中“notify-service-by-email”在commands.cfg文件中定义。​
   host_notification_commands notify-host-by-email ; 主机故障时，发送通知的方式，可以是邮件和短信，这里发送的方式是邮件;​
   ; 其中“notify-host-by-email”在commands.cfg文件中定义。 ​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMPLATE!​
   }​
   define host{​
   name generic-host ; 主机名称，这里的主机名，并不是直接对应到真正机器的主机名;​
   ; 乃是对应到在主机配置文件里所设定的主机名。​
   notifications_enabled 1 ; Host notifications are enabled​
   event_handler_enabled 1 ; Host event handler is enabled​
   flap_detection_enabled 1 ; Flap detection is enabled​
   failure_prediction_enabled 1 ; Failure prediction is enabled​
   process_perf_data 1 ; 其值可以为0或1，其作用为是否启用Nagios的数据输出功能;​
   ; 如果将此项赋值为1，那么Nagios就会将收集的数据写入某个文件中，以备提取。​
   retain_status_information 1 ; Retain status information across program restarts​
   retain_nonstatus_information 1 ; Retain non-status information across program restarts​
   notification_period 24x7 ; 指定“发送通知”的时间段，也就是可以在什么时候发送通知给使用者。​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!​
   }​
   define host{​
   name linux-server ; 主机名称​
   use generic-host ; use表示引用，也就是将主机generic-host的所有属性引用到linux-server中来;​
   ; 在nagios配置中，很多情况下会用到引用。​
   check_period 24x7 ; 这里的check_period告诉nagios检查主机的时间段​
   check_interval 5 ; nagios对主机的检查时间间隔，这里是5分钟。​
   retry_interval 1 ; 重试检查时间间隔，单位是分钟。​
   max_check_attempts 10 ; nagios对主机的最大检查次数，也就是nagios在检查发现某主机异常时，并不马上判断为异常状况;​
   ; 而是多试几次，因为有可能只是一时网络太拥挤，或是一些其他原因，让主机受到了一点影响;​
   ; 这里的10就是最多试10次的意思。​
   check_command check-host-alive ; 指定检查主机状态的命令，其中“check-host-alive”在commands.cfg文件中定义。​
   notification_period 24x7 ; 主机故障时，发送通知的时间范围，其中“workhours”在timeperiods.cfg中进行了定义;​
   ; 下面会陆续讲到。​
   notification_interval 10 ; 在主机出现异常后，故障一直没有解决，nagios再次对使用者发出通知的时间。单位是分钟;​
   ; 如果你觉得，所有的事件只需要一次通知就够了，可以把这里的选项设为0​
   notification_options d,u,r ; 定义主机在什么状态下可以发送通知给使用者，d即down，表示宕机状态;​
   ; u即unreachable，表示不可到达状态;​
   ; r即recovery，表示重新恢复状态。​
   contact_groups ts ; 指定联系人组，这个“admins”在contacts.cfg文件中定义。​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!​
   }​
   define host{​
   name windows-server ; The name of this host template​
   use generic-host ; Inherit default values from the generic-host template​
   check_period 24x7 ; By default, Windows servers are monitored round the clock​
   check_interval 5 ; Actively check the server every 5 minutes​
   retry_interval 1 ; Schedule host check retries at 1 minute intervals​
   max_check_attempts 10 ; Check each server 10 times (max)​
   check_command check-host-alive ; Default command to check if servers are "alive"​
   notification_period 24x7 ; Send notification out at any time - day or night​
   notification_interval 10 ; Resend notifications every 30 minutes​
   notification_options d,r ; Only send notifications for specific host states​
   contact_groups ts ; Notifications get sent to the admins by default​
   hostgroups windows-servers ; Host groups that Windows servers should be a member of​
   register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE​
   }​
   define service{​
   name generic-service ; 定义一个服务名称​
   active_checks_enabled 1 ; Active service checks are enabled​
   passive_checks_enabled 1 ; Passive service checks are enabled/accepted​
   parallelize_check 1 ; Active service checks should be parallelized;​
   ; (disabling this can lead to major performance problems)​
   obsess_over_service 1 ; We should obsess over this service (if necessary)​
   check_freshness 0 ; Default is to NOT check service 'freshness'​
   notifications_enabled 1 ; Service notifications are enabled​

   retain_nonstatus_information 1 ; Retain non-status information across program restarts​
   is_volatile 0 ; The service is not volatile​
   check_period 24x7 ; 这里的check_period告诉nagios检查服务的时间段。​
   max_check_attempts 3 ; nagios对服务的最大检查次数。​
   normal_check_interval 5 ; 此选项是用来设置服务检查时间间隔，也就是说，nagios这一次检查和下一次检查之间所隔的时间;​
   ; 这里是5分钟。​
   retry_check_interval 2 ; 重试检查时间间隔，单位是分钟。​
   contact_groups ts ; 指定联系人组​
   notification_options w,u,c,r ; 这个定义的是“通知可以被发出的情况”。w即warn，表示警告状态;​
   ; u即unknown，表示不明状态;​
   ; c即criticle，表示紧急状态，r即recover，表示恢复状态;​
   ; 也就是在服务出现警告状态、未知状态、紧急状态和重新恢复后都发送通知给使用者。​
   notification_interval 10 ; Re-notify about service problems every hour​
   notification_period 24x7 ; 指定“发送通知”的时间段，也就是可以在什么时候发送通知给使用者。​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!​
   }​
   define service{​
   name local-service ; The name of this service template​
   use generic-service ; Inherit default values from the generic-service definition​
   max_check_attempts 4 ; Re-check the service up to 4 times in order to determine its final (hard) state​
   normal_check_interval 5 ; Check the service every 5 minutes under normal conditions​
   retry_check_interval 1 ; Re-check the service every minute until a hard state can be determined​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!​
   }​
2. hosts.cfg文件​此文件默认不存在，需要手动创建，hosts.cfg主要用来指定被监控的主机地址以及相关属性信息，根据目标配置如下：vim etc/hosts.cfg​
   define host{ //定义主机​
   use linux-server ​
   host_name 192.168.3.200 ​
   alias Oracle​
   statusmap_image linux40.jpg ​
   address 192.168.3.200 ​
   }​
   define host{​
   use linux-server​
   host_name 192.168.3.201​
   alias Weblogic​
   statusmap_image linux40.jpg​
   address 192.168.3.201​
   }​
   define hostgroup{ ​
   hostgroup_name nagios-servers ​
   alias nagios servers ​
   members 192.168.3.200,192.168.3.201 ​
   }​
3. resource.cfg文件​$USER1$=/usr/local/nagios/libexec​
4. 文件​此文件默认是存在的，无需修改即可使用，当然如果有新的命令需要加入时，在此文件进行添加即可。​
   #notify-host-by-email命令的定义 ​
   define command{​
   命令名称，即定义了一个主机异常时发送邮件的命令。​
   command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$ #命令具体的执行方式。​
   }​
   #notify-service-by-email命令的定义 ​
   define command{​
   命令名称，即定义了一个服务异常时发送邮件的命令​
   command_line /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$SERVICEOUTPUT$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$​
   }​
   #check-host-alive命令的定义​
   define command{​
   命令名称，用来检测主机状态。​
   command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5 ​
   这里的变量$USER1$在resource.cfg文件中进行定义，即$USER1$=/usr/local/nagios/libexec;​
   那么check_ping的完整路径为/usr/local/nagios/libexec/check_ping;​
   “-w 3000.0,80%”中“-w”说明后面的一对值对应的是“WARNING”状态，“80%”是其临界值。​
   “-c 5000.0,100%”中“-c”说明后面的一对值对应的是“CRITICAL”，“100%”是其临界值。​
   “-p 1”说明每次探测发送一个包。​
   }​
   define command{​
   command_name check_local_disk​
   是指在调用这个命令的时候，命令后面的第一个参数。​
   }​
   define command{​
   command_name check_local_load​
   command_line $USER1$/check_load -w $ARG1$ -c $ARG2$​
   }​
   define command{​
   command_name check_local_procs​
   command_line $USER1$/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$​
   }​
   define command{​
   command_name check_local_users​
   command_line $USER1$/check_users -w $ARG1$ -c $ARG2$​
   }​
   define command{​
   command_name check_local_swap​
   command_line $USER1$/check_swap -w $ARG1$ -c $ARG2$​
   }​
   define command{​
   command_name check_ftp​
   command_line $USER1$/check_ftp -H $HOSTADDRESS$ $ARG1$​
   }​
   define command{​
   command_name check_http​
   command_line $USER1$/check_http -I $HOSTADDRESS$ $ARG1$​
   }​
   define command{​
   command_name check_ssh​
   command_line $USER1$/check_ssh $ARG1$ $HOSTADDRESS$​
   }​
   define command{​
   command_name check_ping​
   command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5​
   }​
   define command{​
   command_name check_nt​
   command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$​
   }​
5. contacts.cfg文件​contacts.cfg是一个定义联系人和联系人组的配置文件，当监控的主机或者服务出现故障，nagios会通过指定的通知方式（邮件或者短信）将信息发给这里指定的联系人或者使用者。​
   define contact{​
   contact_name nagiosadmin ; Short name of user​
   use generic-contact ; Inherit default values from generic-contact template (defined above)​
   alias Nagios Admin ; Full name of user​
   
   email nagios@localhost ​
   }​
   define contact{​
   contact_name zrsfadmin ; Short name of user​
   use generic-contact ; Inherit default values from generic-contact template (defined above)​
   alias Zrsf Admin ​
   email zcm_mail@126.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******​
   }​
   define contactgroup{​
   contactgroup_name admins​
   alias Nagios Administrators​
   members nagiosadmin​
   }​
   #####add by zhaocm20140509#####​
   define contactgroup{​
   contactgroup_name ts​
   alias Test​
   members zrsfadmin​
   }​
6. timeperiods.cfg文件​此文件只要用于定义监控的时间段，使用默认模板文件。​
7. nagios.cfg文件​nagios.cfg默认的路径为/usr/local/nagios/etc/nagios.cfg，是nagios的核心配置文件，所有的对象配置文件都必须在这个文件中进行定义才能发挥其作用，这里只需将对象配置文件在Nagios.cfg文件中进行引用即可。​
   log_file=/usr/local/nagios/var/nagios.log # 定义nagios日志文件的路径​

4. 
   
5. 删除或者重命名/usr/local/pnp4nagios/share/install.pnp​

[root@nagios-server share]# mv install.php install.php.bak​

1. 整合Nagios

1. 配置apache​将/etc/httpd/conf.d/pnp4nagios.conf中的所有内容全部添加到apache的httpd.conf文件最后。​
   # cat /etc/httpd/conf.d/pnp4nagios.conf >>/usr/local/apache2/conf/httpd.conf​
2. 创建配置文件​# cd /usr/local/pnp4nagios/etc​
   # misccommands.cfg​
   # nagios.cfg​
   # mv mv rra.cfg-sample rra.cfg​
   # process_perfdata.cfg​

   # mv web_traffic.cfg-sample web_traffic.cfg​
   # cd ../check_commands​
   # check_all_local_disks.cfg​
   # check_nrpe.cfg​
   # check_nwstat.cfg​
3. 重启服务​# /etc/init.d/npcd restart​
4. 修改 nagios 的配置文件​修改/usr/local/nagios/etc/nagios.cfg文件，内容如下:​
   process_performance_data=1​
   host_perfdata_command=process-host-perfdata​
   service_perfdata_command=process-service-perfdata​
   enable_environment_macros=1​
5. 修改command.cfg配置文件​编辑/usr/local/nagios/etc/objects文件，将原有的process-host-perfdata和process-service-perfdata注释点，添加如下内容：​
   definecommand{​
   command_name process-host-perfdata​
   command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA​
   }​
   define command{​
   command_name process-service-perfdata​
   command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl​
   }​
6. 添加图标模块​编辑/user/local/nagios/etc/object/template.cfg文件，linux-server和generic-service中分别，添加action_url​
   action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_​
   action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$​
7. 重启nagios服务​

#/etc/init.d/nagios restart​

1. 安装NRPENRPE是监控软件nagios的一个扩展，它被用于被监控的服务器上，向nagios监控平台提供该服务器的一些本地的情况。例如，cpu负载、内存使用、硬盘使用等等。NRPE可以称为nagios的for linux 客户端。

2. Nrpe监控原理



3. NRPE总共由两部分组成：

• check_nrpe 插件，位于监控主机上​
• NRPE daemon，运行在远程的Linux主机上(通常就是被监控机)​
• 按照上图，整个的监控过程如下：​
• 当Nagios 需要监控某个远程Linux 主机的服务或者资源情况时：​
• Nagios 会运行check_nrpe 这个插件，告诉它要检查什么；​
• check_nrpe 插件会连接到远程的NRPE daemon，所用的方式是SSL；​
• NRPE daemon 会运行相应的Nagios 插件来执行检查；​
• NRPE daemon 将检查的结果返回给check_nrpe 插件，插件将其递交给nagios做处理。​
• 注意：NRPE daemon 需要Nagios 插件安装在远程的Linux主机上，否则，daemon不能做任何的监控。​

2. 在被监控机（Nagios-Linux）上，源码安装nagios插件​

# useradd nagios​

# passwd nagios​

# tar zxvf nagios-plugins-1.4.16.tar.gz​

# cd nagios-plugins-1.4.16​

# ./configure --prefix=/usr/local/nagios​

# make && make install​

# chown nagios.nagios /usr/local/nagios​

# chown -R nagios.nagios /usr/local/nagios/libexec​

# tar zxvf nrpe-2.13.tar.gz​

# cd nrpe-2.13​

# ./configure​

# make all​

# make install-plugin​

# make install-daemon​

# make install-daemon-config​

# make install-xinetd​

1. 在被监控机上添加监控主机IP地址​编辑/etc/xinetd.d/nrpe文件在only_from 后增加监控主机的IP地址。​
   # default: on​
   # description: NRPE (Nagios Remote Plugin Executor)​
   service nrpe​
   {​
   flags = REUSE​
   socket_type = stream​
   port = 5666​
   wait = no​
   user = nagios​
   group = nagios​
   server = /usr/local/nrpe/bin/nrpe​
   server_args = -c /usr/local/nrpe/etc/nrpe.cfg --inetd​
   log_on_failure += USERID​
   disable = no​
   only_from = 127.0.0.1 192.168.3.202​
   allowed_hosts = 192.168.3.202​
   }​
2. 在被监控机上增加NRPE服务​编辑/etc/services 文件，增加NRPE服务​
   # Local services​
   nrpe 5666/tcp # nrpe​
3. 在被监控机上重启xinetd服务：​#service xinetd restart​
4. 在被监控机上测试NRPE是否则正常工作​在被监控机上安装的check_nrpe 这个插件测试NRPE 是否工作正常​
   # /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1​
   NRPE v2.13​
5. 添加命令定义​

在监控机上编辑/usr/local/nagios/etc/objects/commands.cfg文件，添加如下内容：​

# 'check_nrpe' command definition by zhaocm 20140529​

define command{​

command_name check_nrpe ​

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$​

}​

4. 修改启动脚本(如下)：​编辑/opt/wlsagent-r185/run.sh，修改后文件如下：​
   #!/bin/bash​
   cd $(dirname "$0")​
   JAVA_HOME="/opt/jdk1.6.0_30"​
   HOST="0.0.0.0"​
   PORT="9090"​
   CLASSPATH=".:wlsagent-r185.jar"​
   # Add Jetty dependencies to the plugin classpath.​
   CLASSPATH="${CLASSPATH}:lib/servlet-api-2.5.jar:lib/jetty-servlet-7.6.2.v20120308.jar" ​
   # Add WebLogic dependencies to the plugin classpath.​
   # The 'wljmxclient.jar' must be loaded before the 'wlfullclient.jar'.​
   CLASSPATH="${CLASSPATH}:lib/wlclient.jar:lib/wljmxclient.jar:lib/wlfullclient.jar"​
   ${JAVA_HOME}/bin/java -Xmx32m -cp ${CLASSPATH} net.wait4it.nagios.wlsagent.core.WLSAgent ${HOST} ${PORT} > /dev/null 2>&1 &​
   注意JAVA_HOME和java工程包的路径。​
5. 添加需要jar包​进入$weblogic/wlserver_10.3/server/lib下，生成wlfullclent.jar，将wlclient.jar wljmxclient.jar包一起复制到/opt/wlsagent-r185/lib/​
   #cd /wlserver_10.3/server/lib​
   # java -jar wljarbuilder.jar​
   # cp wlclient.jar wljmxclient.jar wlfullclient.jar /opt/wlsagent-r185/lib/​
   添加后的jar​
   # ls /wlserver_10.3/server/lib​
   jetty-servlet-7.6.2.v20120308.jar servlet-api-2.5.jar wlclient.jar wlfullclient.jar wljmxclient.jar​
6. 本地测试​

#/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014'​

或者​

#wget -q -O - 'http://localhost:9090/wlsagent/WlsAgent' --post-data='hostname=nagios2&port=7001&username=weblogic&password=weblogic2014' ​

若有返回信息如下：​

wlfpAdmin is in RUNNING state, status OK|​

表明安装成功。​

1. 远程监控配置

1. 安装npre插件（同上）​
2. 安装 nagios-plugins插件（同上）​
3. 被监控端添加监控内容​编辑/usr/local/nagios/etc文件，添加如下内容：​
   command[check_status]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014'​
   command[check_jvm]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&jvm=UsedMemory,80,90'​
   command[check_jvm2]=wget -q -O - 'http://localhost:9090/wlsagent/WlsAgent' --post-data='hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&jvm=UsedMemory,80,90'​
   command[check_thread-pool]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&thread-pool=ThreadStuckCount,5,10'​
   command[check_jta]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&jta=ActiveTransactions,15,30'​
   command[check_jmsRuntime]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&jms-runtime=CurrentConnections,500,750'​
   command[check_jme-queue]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&jms-queue=*,150,200'​
   command[check_component]=/opt/wlsagent-r185/wlsagent.sh 'hostname=nagios2&port=7001&username=weblogic&password=weblogic2014&compnotallow=*,100,150'​
4. 监控端远程测试​[root@nagios-server libexec]# /usr/local/nagios/libexec/check_nrpe -H 192.168.3.201 -c check_status​
   wlfpAdmin is in RUNNING state, status OK|​
5. 监控端添加服务​编辑/usr/local/nagios/etc/service/weblogic.cfg文件，添加如下内容：​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_jvm​
   process_perf_data 1​
   check_command check_nrpe!check_jvm​
   }​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_jvm2​
   check_command check_nrpe!check_jvm2​
   }​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_thread-pool​
   check_command check_nrpe!check_thread-pool​
   }​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_jta​
   check_command check_nrpe!check_jta​
   }​
   
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_jmsRuntime​
   check_command check_nrpe!check_jmsRuntime​
   }​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_jme-queue​
   check_command check_nrpe!check_jme-queue​
   }​
   define service{​
   use local-service​
   host_name 192.168.3.201​
   service_description weblogic_component​
   check_command check_nrpe!check_component​
   }​
6. 将weblogic.cfg加载​编辑/usr/local/nagios/etc/nagios文件，添加如下：​
   cfg_file=/usr/local/nagios/etc/service/weblogic.cfg​
7. 重启监控端nagios和和被监控端nrpe服务，web访问如下：​

2. 编写脚本

1. 安装perl环境及相应的perl模块，依次安装LWP::Simple URI::Escape Digest::MD5模块，可使用yum或者CPAN命令安装。​
2. /usr/local/nagios/libexec目录下，新建sms_send.pl脚本，内容如下：#!/usr/bin/perl -w
   use strict;
   use LWP::Simple;
   use URI::Escape;
   use Digest::MD5;
   my ($mobile, $content) = @ARGV; # get params from command line
   my $log_control = 1; # a switch of log
   my $username = '******'; # your sms service username
   my $password = '******'; # your sms service password
   my $key = ''; # your sms service key
   my $souce_content = substr($mobile, 0, 8) . substr($mobile, -10, 10) . $key;
   my $md5 = Digest::MD5->new;
   $md5->add($souce_content);
   my $keyword = uc($md5->hexdigest);
   my $result = get "http://211.147.224.154:18013/cgi-bin/sendsms?username=$username&password=$password&to=$mobile&text=$content&Keyword=$keyword";
   if($log_control) {
   my $fh;
   open($fh, '>> /var/log/sms.log') or die "can't open log: $!"; # make sure have permission
   print $fh join(' ', time, $result, "/n");
   close $fh;
   }
   示例说明：

1. my $key = '’ 短信服务商给的验证关键字，如没有可以设为空值。​
2. my $url=​

以短信服务商广州玄武科技公司提供的网关通道为例说明： ​​http://211.147.224.154:18013/cgi-bin/sendsms?username=$username&password=$password&to=$mobile&text=$content&Keyword=$keyword&subid=&msgtype=4”url​​中包含用户名、密码、关键字、电话号码、发送内容、长短信协议等等。
chomod u+x /usr/local/nagios/libexec/sms_send.pl 给与它执行权限。​

1. 测试​

执行命令行/usr/local/nagios/libexec/sms_send.pl 13800138000 "It is a test"​

1. 配置​

1. Nagios配置​
2. Pnpnagios安装​Pnpnagios实现nagios服务图表，它利用RRDTool工具将Nagios的数据生成图形，以便更直观的查看，而且可以查看历史记录。​
3. Centos监控​
4. Oracle监控​check_oracle_health 是一个 Nagios 用来监控Oracle 数据库运行状态的插件。可监控的内容包括：连接时间、SGA 数据缓冲区的使用率、命中率以及可用空间、PGA 内存排序的命中率、表空间的使用率、表空间碎片、表空间IO瓶颈、无效对象以及其他很多方面的数据监控内容。​

5. Weblogic监控​Wlsagent是一个nagios的插件程序,可监控WebLogic服务器(9x,10x & 11g版本),而且最小可能占用服务器内存的程序.目前可提供JVM、THREAD POOL、JTA、JDBC、JMS、 HTTP SESSION等监控。​
6. 短信网关配置​

1. 安装配置​
2. 监控配置​
3. 修改command.cfg文件,增加短信报警部分​# 'notify-host-by-sms' command definition
   define command{
   command_name host-notify-by-sms
   command_line /usr/local/nagios/libexec/sms_send.pl $CONTACTPAGER$ "*** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ IP: $HOSTADDRESS$ is $HOSTSTATE$ ***"
   }
   # 'notify-service-by-sms' command definition
   define command{
   command_name service-notify-by-sms
   command_line /usr/local/nagios/libexec/sms_send.pl $CONTACTPAGER$ "*** $NOTIFICATIONTYPE$ Service Alert: $HOSTNAME$ IP: $HOSTADDRESS$ / $SERVICEDESC$ is $SERVICESTATE$ ***"
   }​
4. 修改templata.cfg文件,增加通知选项​define contact{​
   name generic-contact ; The name of this contact template​
   service_notification_period 24x7 ; service notifications can be sent anytime​
   host_notification_period 24x7 ; host notifications can be sent anytime​
   service_notification_options w,u,c,r,f,s ; send notifications for all service states, flapping events, and scheduled downtime events​
   host_notification_options d,u,r,f,s ; send notifications for all host states, flapping events, and scheduled downtime events​
   service_notification_commands notify-service-by-email,service-notify-by-sms ; send service notifications via email​
   host_notification_commands notify-host-by-email,host-notify-by-sms ; send host notifications via email​
   register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMPLATE!​
   }​
5. 修改contacts.cfg文件，定义联系人​define contact{​
   contact_name zrsfadmin ; Short name of user​
   use generic-contact ; Inherit default values from generic-contact template (defined above)​
   alias Zrsf Admin​
   email zcm_mail@126.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS​
   pager 18576652571​
   }​
6. 4.重启nagios服务​
