nagios机器分组批量检测

我一直不太喜欢用nagios，主要原因是配置太过复杂，有些时候可能自己写几行脚本就能搞定的事情却要修改一堆配置，太麻烦了。插件虽然很多但也会常常需要二次开发，实在没有那个精力。

这里说说今天改配置文件时候发现的一些技巧，在监控大量服务器时会更省力一些

一。在nagios.cfg中加入

#groupfile
cfg_file=/usr/local/nagios/etc/objects/hostsgroup.cfg
cfg_file=/usr/local/nagios/etc/objects/groupservers.cfg



二。监控组模板配置，这个模板写好以后，可以在需要时调用，非常的方便。

/nagios/etc/objectsgroupservers.cfg



define service{
use local-service ; Name of service template to use
hostgroup_name   Webserver
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}

# Define a service to check SSH on the local machine.
# Disable notifications for this service by default, as not all users may have SSH enabled.

define service{
        use                             local-service         ; Name of service template to use
        hostgroup_name   Webserver
        service_description             SSH
        check_command                   check_ssh
        notifications_enabled           1
        }



# Define a service to check HTTP on the local machine.
# Disable notifications for this service by default, as not all users may have HTTP enabled.

define service{
        use                             local-service         ; Name of service template to use
        hostgroup_name   Webserver
        service_description             HTTP
        check_command                   check_http
#       notifications_enabled           0
        }
#Define a service to check squid on the local machine
define service{
        use                             local-service         ; Name of service template to use
        hostgroup_name   Webserver
        service_description             SQUID
        check_command                   check_squid
        }

#CPU Load
define service{
          use                 local-service
          hostgroup_name   Webserver
          service_description CPU Load
          check_command       check_nrpe!check_load
    }
#User Login
define service{
          use                 local-service
          hostgroup_name   Webserver
          service_description Current user
          check_command       check_nrpe!check_users
    }
#Total Processes
define service{
          use                 local-service
          hostgroup_name   Webserver
          service_description Total Processes
          check_command       check_nrpe!check_total_procs
    }




  三。调用。在此处调用的机器，在hosts.cfg中一定要声明过，否则nagios将无法启动



define hostgroup{
       hostgroup_name   Webserver
       alias            Webserver     ;在web界面显示的名字
       members    web1
}
