# NOTE! FQDN lookup is enabled by default. This might give you troubles if you'r running on Vagrant or some cloud server
# Check /var/log/messages for something like "Looking up "<yourhost>" failed. You have set the "FQDNLookup" option, but I cannot resolve my hostname...
# The fix is easy, just set "FQDNLookup   false" in /etc/collectd.conf
