We are having a standalone harvest installation which collects metrics from all filers/clusters. Since the number of storage to monitor is more, we are setting up pollers on remote site which sends data to US graphite server. All the modules are confired on the poller but its not sending any data to graphite server. Below is the error from the log from poller host

Carbon/httpd is running on remote graphite server "harvest-server". No firewall is in place as i can telnet to "harvest-server" from the poller. Can someone assist on what could be the issue here?
thanks
