windows.cfg，本实验主要采用组进行配置，此文档不删掉不使，下面配置供参考。


definehost{
use  windows-server ; Inherit default values from a template

e. services.cfg文件
此文件默认也不存在，需要手动创建，services.cfg文件主要用于定义监控的服务和主机资源，例如监控http服务、ftp服务、主机磁盘空间、主机系统负载等等。Nagios-Server 和Nagios-Windows 相关服务已在相应的配置文件中定义，所以这里只需要定义Nagios-Linux 相关服务即可，这里只定义一个检测是否存活的服务来验证配置文件的正确性，其他服务的定义将在后面讲到。
define service{
use   local-service  ; #引用local-service服务的属性值，local-service在templates.cfg文件中进行了定义。
host_name  Nagios-Linux  ; #指定要监控哪个主机上的服务，“Nagios-Server”在hosts.cfg文件中进行了定义。
service_description PING   ; #对监控服务内容的描述，以供维护人员参考。
contact_groups  linuxcontact
check_command  check-host-alive ; #指定检查的命令。
}
define service{
use   local-service
host_name  Nagios-Linux
service_description CurrentLoad
contact_groups  linuxcontact
check_command  check_nrpe!check_load
}
define service{
use   local-service
host_name  Nagios-Linux
service_description TotalProcesses
contact_groups  linuxcontact
check_command  check_nrpe!check_total_procs
}
define service{

host_name  Nagios-Linux
service_description CurrentUsers
contact_groups  linux contact
check_command  check_nrpe!check_users
}
define service{
use   local-service
host_name  Nagios-Linux
service_description CheckZombie Procs
contact_groups  linuxcontact
check_command  check_nrpe!check_zombie_procs
}
define service{
use   local-service
host_name  Nagios-Linux
service_description Check Swap
contact_groups  linux contact
check_command  check_nrpe!check_swap
}

f. contacts.cfg，contactgroup.cfg文件，默认不存在，需手动创建！
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。contactgroup.cfg定义联系人组的配置文件，注意：members选项里面的联系人在contacts.cfg里面要要定义，多个联系从之间用逗号隔开。
contacts.cfg下面的配置文档
definecontact{
contact_name   echo   ; Short name of user
use    generic-contact  ; Inheritdefault values from generic-contact template (defined above)
alias    linux contact  ; Full name of user
