[collectd] collectd[3112]: write_graphite plugin: Connecting to localhost:2003 via tcp failed

[Giovanni Torres]

You may need to add a Server line to the network plugin:
# server
<Plugin "network">
 Server "192.168.122.40"
 Listen "192.168.122.40"
</Plugin>

Other things to check since I am not familiar with your setup:

If you run netstat, is the carbon port listening on 0.0.0.0:2003?  (from a remote machine, `telnet x.x.x.x 2003`)
Do you have iptables running?
Check either /var/log/messages or /var/log/audit/audit.log for avc selinux denials.
