[one-users] What remotes commands does one 4.6 use:

Wed Jul 30 04:17:18 PDT 2014

Maybe you could try to execute the  monitor probes in the node,

1. ssh the node
2. Go to /var/tmp/one/im
3. Execute run_probes kvm-probes

Make sure you do not have a host using the same hostname fgtest14 and
running a  collectd process
