thanks for the reply
Actually i didn't find the hosts.cfg file .. that's why i asked that question .can i create my own .cfg file called "myhosts.cfg" in /usr/local/nagios/etc/ and add it in nagios.cfg file
Sure you can. Did you run "make install-config" ? that should have created soma example config files.
