***> One or more problems was encountered while processing the config files...

     Check your configuration file(s) to ensure that they contain valid
     directives and data defintions.  If you are upgrading from a previous
     version of Nagios, you should be aware that some variables/definitions
     may have been removed or modified in this version.  Make sure to read
     the HTML documentation regarding the config files, as well as the
     'Whats New' section to find out what has changed.

出现这种问题我解决的办法如下：

首先确保

需要在commands.cfg 中加入check_nrpe 的插件配置

#vi commands.cfg 进入后按shift+g 切到结尾加入下面内容。

# ‘check_nrpe‘ command definition

define command{

command_name check_nrpe

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

}

cfg_file=/usr/local/nagios/etc/objects/hosts.cfg
cfg_file=/usr/local/nagios/etc/objects/services.cfg
cfg_dir=/usr/local/nagios/etc/objects/services

我曾经对此配置文件做了如上修改：

却发现没有创建services目录

等我创建了service目录后，发现，可以正常运行了
