Facing Issue in Nagios 3.3

Hi,

I have installed Nagios on Redhat Linux,

I have installed Nagios+Plugins+NRPE on Server A (Host Server) and Nagios Plugins + nrpe on remote linux server (red hat linux)

run the command on remote linux host, it returns nrpe version

usr/local/nagios/libexec/check_nrpe -H localhost

run the command from Nagios Host Server

/usr/local/nagios/libexec/check_nrpe -H 192.168.2.3 (remote linux host)

it has return the nrpe version

now whenever I opening web browser and going to services, it is showing all the crtical and showing plugins are missing

I have run the below command on Nagios server

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

it is showing 0 Warning.

also it is not showing any cpu and memory graph.

Check the nrpe.cfg file in the client (check how the commands are defined and also make sure nagios plugins are installed in server and client and also make sure you have defined the command definition on Server A.
