Error running cluesserver command

[alvarosimon]

Hi

We are playing around with Clues in our OpenNebula cluster, we have followed the doc example to use our ONE endpoint (clues and oned are running in the same CentOS7 machine) but we get this error running the command:

# /usr/bin/cluesserver

Do you know where the issue is? we are using ONE 4.12.1 in our case

Thanks in advance! Alvaro

Hi,

The error happened because some of the values obtained from the hosts in ONE is "None".

We have just corrected the error and we have pushed a new version of the cpyutils. Please update the installation of the cpyutils.

We think that the issue is related to ONE 4.12.1, in which we have not tested CLUES yet. The error maybe happened because any of fields from the information model of ONE has changed. So, please forgive some problems that may happen until the new version of ONE is tested.

Regards, Carlos A.

Hi Carlos Thanks a lot for your quick answer! I have upgraded cpyutils to the new version and now we don't get the error message. As you said it seems that something has changed in ONE 4.12.1, we get these warnings from our log:

...

Cheers and thanks! Alvaro

Hi,

those variables are not needed by CLUES, yet. So CLUES should be working fine.
