Hi Carlos,
I have checked the directory /var/tmp/one/vmm/xen in the nodes and
/$ONE_LOCATION/var/remotes/vmm/xen in the front-end, the content of both
is the same. This means that the update has been made correctly in the
nodes.
I have looked in log file the error before the update and it is
different. The messages are the following, in case they can help.
*BEFORE*
Error executing sudo /usr/sbin/xentop -bi2
/var/tmp/one/vmm/xen/poll:186:in `[]': can't convert String into Integer
(TypeError)
from /var/tmp/one/vmm/xen/poll:186:in `get_vm_info'
from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'
from /var/tmp/one/vmm/xen/poll:348
ExitCode: 1
Error monitoring VM, Error executing sudo /usr/sbin/xentop -bi2
*AFTER*
Error executing sudo /usr/sbin/xentop -bi2
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method `[]'
for nil:NilClass (NoMethodError)

You can say to me if I can test some to help in this.
Thank you very much in advance.
Regards,
María

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

Hi Carlos,
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.
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.
[oneadmin@dn07 ~]$ /var/tmp/one/vmm/xen/poll one-28
Error executing sudo /usr/sbin/xentop -bi2
/var/tmp/one/vmm/xen/poll:186:in `get_vm_info': undefined method
`[]' for nil:NilClass (NoMethodError)
from /var/tmp/one/vmm/xen/poll:314:in `print_one_vm_info'
from /var/tmp/one/vmm/xen/poll:348
Can you think of any other thing that I could test?
Thank you very much in advance.
BR,
María

Hi again,
The script was discarding the first lines, because other versions
include some information about the system before the list of domains.
Please try the patch attached in this new ticket:
http://dev.opennebula.org/issues/656
Thank you,
Carlos.

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?
Thank you very much.

María

Hi María,
It looks like the script is not getting the expected output
format and fails to parse it.
Could you please copy the output of 'sudo /usr/sbin/xentop
-bi2', logged as oneadmin in the Host?
Regards,
Carlos.

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