I’m new here and I have searched Google for the issue I am encountering, but have had no luck in finding a resolution. I have Nagios 3.2.0 installed on an Ubuntu 9.04 system and I have agents installed on multiple Windows Servers. Nagios is able to monitor the Windows systems perfectly, but I am having problems getting Nagios to monitor the system it is running on. While I am testing, I do have the firewall (ufw) turned off on the monitoring host. I am getting these errors in the Nagios log:
localhost;Memory Usage;CRITICAL;notify-service-by-email;Connection refused
localhost;CPU Load;CRITICAL;notify-service-by-email;Connection refused
I find it strange because the other alarms, Current Load, Curent Users, Root Partition, etc… for the localhost are green.
Any assistance would be appreciated.
