Hi

I need to monitor windows services(like CPU load, memory usage etc.), so I have installed Nagios monitoring tool. The installation is complete and 'check_nt' plugin is also installed. Upto this no error is there, but while executing scripts with agent NSClient++ 'Connection refused by host' error still persists.

./check_nt -H 10.112.32.78 -p 1248 -v MEMUSE -w 80 -c 90
Connection refused by host

./check_nt -H 10.112.32.78 -p 1248 -v MEMUSE -w 80 -c 90
Socket timeout after 10 seconds
I have verified that nagios is working correctly, as under.

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