The nagios users check_ping result is: PING OK - Packet loss = 0%, RTA = 0.07 ms
The SELinux is not enabled because I installed ganglia monitor too. And there is no message like 'avc denied' in /var/log/message and the output of command audit2allow is blank.
Thanks

Hmm. That's an unexpected result. The next step would be to go one level
higher and execute nagios' check_ping as the nagios user --
/path/to/nagios/libexec/check_ping -H 192.168.0.1 -w 3000.0,80% -c
5000.0,100% -p 1
Do you have SELinux enabled? Have you modified the default policies? I'd
look for 'avc denied' messages related to nagios in /var/log/messages
just to be safe or, as root, run 'audit2allow -l -i /var/log/messages
-v'.
