It appears as though you do not have permission to view information for any of the hosts you requested...
If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.
修改/usr/local/nagios/etc/cgi.cfg
# vi /usr/local/nagios/etc/cgi.cfg
找到use_authentication=1,将1修改为0,保存退出。
# service nagios restart
