Hi,<br><br>Maybe the problem is that OpenNebula copies updated files when the monitorization takes place.<br>Could you please check that /var/tmp/one/vmm/xen/poll in your remote host has the updated code?<br><br>Anyway, we are going to test this issue in our local infrastructure, hopefully we'll come up with a fix soon.<br>

Hi Carlos,<br>
<br>
Before anything else, sorry for the delay in my answer.I have been
very busy this past month and I haven't been able to test the patch
that you prepared to solve the monitoring problem. <br>
<br>
Finally last week I tested the patch but the monitoring problems
continue although the machines no longer happen to unknown state. I
have executed from line of commands but the messages are the same
that they appear registered in logs.<br>
<br>
[oneadmin@dn07 ~]$ /var/tmp/one/vmm/xen/poll one-28<div class="im"><br>
Error executing sudo /usr/sbin/xentop -bi2<br></div>
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method
`[]' for nil:NilClass (NoMethodError)<br>
from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'<br>
from /var/tmp/one/vmm/xen/poll:348<br>
<br>
<br>
Can you think of any other thing that I could test?<br>
<br>
Thank you very much in advance.<br>
BR,<br>

The script was discarding the first lines, because other versions
include some information about the system before the list of

Hi Carlos,<br>

The output of 'sudo /usr/sbin/xentop -bi2' is:<br>

<br>
This error causes that the VM is not monitored correctly,
also the machines happen to unknown state. Do you think that
this error will have something to do with the unknown state
of the VM?<br>
<br>
<br>
Thank you very much.<br>
Regards,<br>

I have another problem with the monitoring of

I have tried to execute the commando from the
own node to discard problems of ssh, but the
error message is the same.<br>
<br>
I have found the following information <br>
<br>
<a href="http://dev.opennebula.org/issues/567" target="_blank">http://dev.opennebula.org/issues/567</a><br>
<br>
but this patches no solved this problem. I have
installed opennebula 2,2 and the nodes are xen
3.4.3<br>
<br>
Any idea? Thank you very much by your attention.<br>
