[one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]

Thu Mar 8 09:04:36 PST 2012

Yes,

I mean the contents of the directory. run_probes, just executes the scripts
in /var/tmp/one/im/kvm.d (in your case). The reason for no output of
run_probes is an empty kvm.d. Could you check the contents of that
directory (and execute any script there....)?

BTW run_probes is a very simple shell script (similar to run_parts) you may
want to execute it with bash -xv /var/tmp/one/im/run_probes kvm 4 pcls
