Nagios 安装PNP(类似Cacti)绘图查看监控主机

willyomg

Nagios 安装过程请看 http://bbs.linuxtone.org/thread-2201-1-1.html 这里省略
下载pnp-0.4.13.tar.gz
tar zvxf pnp-*
cd pnp*
./configure
当显示出以下信息，就表示配置正常

1. Nagios 2.x
   
2. Until nagios 2.10 the integration of external URLs into the nagios web interface occurs using Extended Info Objects. For PNP we use the directive action_url to call the PNP web frontend with the appropriate options.
   
3. define serviceextinfo {
   
4. host_name localhost
   
5. service_description load
   
6. action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
   
7. }
   
8. 
   
9. Nagios 3.x
   
10. Since nagios 3.0 the action_url-directive has be moved to the host or service definition. The objects serviceextinfo and hostextinfo do not apply anymore. This way the definition of URLs to the PNP-interface have been simplified.
    
11. define host {
    
12. name host-pnp
    
13. register 0
    
14. action_url /nagios/pnp/index.php?host=$HOSTNAME$
    
15. }
    
16. define service {
    
17. name srv-pnp
    
18. register 0
    
19. action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
    
20. }

我这里安装的时nagios 3.0.6，所以要在templates.cfg 的最后添加
define host {
  name       host-pnp
  register   0
  action_url /nagios/pnp/index.php?host=$HOSTNAME$
}
define service {
  name       srv-pnp
  register   0
  action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
}
Since Nagios 3.x it is possible to deactivate the export of environment variables (as part of optimizing the system for maximum performance). Unfortunately this directive has to be enabled to use the default mode. So either you use the default value (which means that the export is enabled) or you define the variable in nagios.cfg
enable_environment_macros=1Additionally the command to process performance data is to be specified in nagios.cfg
service_perfdata_command=process-service-perfdataStarting with Nagios 3.0 it may be useful to enable processing of performance data for hosts as well. Due to changed host check logic Nagios 3 now performs regularly scheduled host checks.
host_perfdata_command=process-host-perfdata

在commands.cfg 添加一下
define command {
  command_name    process-service-perfdata
  command_line    /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl
}

define command {
  command_name    process-host-perfdata
  command_line    /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}
在一个要使用pnp监控的主机配置文件里，比如 localhost.cfg 修改以下内容
define host{
        use                     linux-server,host-pnp                                                                                                                           
        host_name               localhost
        alias                   localhost
        address                 127.0.0.1
        action_url              /nagios/pnp/index.php?host=$HOSTNAME$
        process_perf_data 1
        }

define service{
        use                             local-service,srv-pnp                host_name                       localhost
        service_description             PING
        check_command                   check_ping!100.0,20%!500.0,60%
        process_perf_data 1
        }
以此类推，祝大家好运！
