===Nagios file configuration===

Make sure that you make a entry on nagios file( vim /usr/local/nagios/etc/nagios.cfg)

In That file specify the file which you are created and define the host

cgi_file=/usr/local/nagios/etc/objects/linuxbox.cfg
cgi_dir=/usr/local/nagios/etc/service

== Define client details ==

== Configuration Of Warning and Critical Mail send by Nagios: ==

#Vim /usr/local/nagios/etc/objects/contacts.cfg

DEFINE CONTACT

define contact{
contact_name mailtest ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user

email test@tetrain.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******

define contactgroup{
contactgroup_name client-group
alias Nagios Administrators
members mailtest
}

Note : Now the client have to see only there services not all clients services for that we made new contact group i.e mailtest and now we want that they can wacth there services but do not change any thing for that we do one entry in below :

# vim /usr/local/nagios/etc/cgi.cfg
#authorized_for_read_only=user1,user2
authorized_for_read_only=mailtest

Note : Set password for user mailtest

# htpasswd htpasswd.users mailtest

Then check your mail.

TROUBLESHOOTING----------------

1. Check nagios port is open on client server
#nc -z client ip 5666

2. check client server is connected or not
#./usr/local/nagios/libexec/check_nrpe -n -H spimail.spi.com

3. check service
#/usr/local/nagios/libexec/check_nrpe -n -t 50 -H spimail.spi.com -c check_mem_avail
