This error is coming because the missing of check_mem command on the client machine

open the following file and add the command as follows

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# vi /usr/local/nagios/etc/nrpe.cfg
command[check_mem]=/usr/local/nagios/libexec/check_mem 85 95
save the file. That it.

root@server1 [~]# /usr/local/nagios/libexec/check_mem 85 95
OK - Memory usage is 2.000%
