Yup now it is ok ... but i have now new problem ... i create new file in objects named routers.cfg ... and i put one host with service ping to check ... and in the nagios/etc nagios.cfg file i have add the the routers.cfg file and when i try to restart it gave me the status of the configurations like when i run the command /usr/local/nagios/bin/nagio -v /usr/local/nagios/etc/nagios.cfg and when i go to the page on services iv got this error message
Whoops!
Error: Could not read host and service status information!
The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios.
Some other things you should check in order to resolve this error include:
Check the Nagios log file for messages relating to startup or status data errors.
Always verify configuration options using the -v command-line option before starting or restarting Nagios!
Make sure you read the documentation on installing, configuring and running Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at
http://www.nagios.org.
also i have notes that when i do ls i have dots "." at the end of the permission colon
[root@mpnagios etc]# ls -la
total 76

The period is related to SELinux ACLs:

As for whether or not that is related, I do not know.

No still nothing ... any way i think that thats not a problem at all ... because i can modify the nagios.cfg file, for example if i uncomment "#cfg_file=/usr/local/nagios/etc/objects/switch.cfg" it works ... but if i add another file like routers.cfg it wont work ...

Where did you put the routers.cfg, and what permissions are presently on it?

What does it say when you run Nagios' configuration check? (Adjust it if your paths are different)
Code: Select all
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
If there's a problem with your configuration files, the config check will print the name of the offending file and the line number in that file. That'll tell us where to look next.

Did you change anything else? Config warnings should not cause this issue.
