Engine 20.10.4 with Perl connector: Execute command failed

[joschi99]

After update engine from 20.10.2 to 20.10.4 all services with perl connector are not more working

• status: UNKNOWN
• Execute command failed

On /var/log/centreon-engine/centengine.log we can see a lot of messages like this:

Same problem here after an upgrade from the latest 19.04 to 20.04.13.

When I tested the upgrade on another platform, some weeks ago, it was Centreon Web 20.04.12 and I experienced absolutely no problem. So I expected no problem for this new upgrade, as from 20.04.12 to 20.04.13 it’s only one revision. Things should not break like this on a revision upgrade. (IMHO)

Centreon Engine is 20.04.11 on both plateform, so I guess the problem is more related to Centreon Web than Centren Engine. Centreon Broker and Gorgone also are at the same revision : 20.04.13 and 20.04.10.

Hi @joschi99 / @StefThomas

Could you please paste the content of /etc/centreon-engine/connectors.cfg file please?

Just to be sure, did you restart the engine? Did you update the centreon-clib package also?

What's your versions please:

rpm -qa |egrep "(centreon-clib|centreon-engine|centreon-broker)"

[joschi99]

rpm -qa |egrep "(centreon-clib|centreon-engine|c                                   entreon-broker)"

centreon-broker-20.10.4-5.el7.centos.x86_64

centreon-clib-20.10.1-2.el7.centos.x86_64
centreon-broker-core-20.10.4-5.el7.centos.x86_64

yes, I confirm that centreon engine has been restarted. I have riproduced the problem also on a test environment.

Thanks, I reproduced.

Stay tuned

PS: In the meantime, disable perl connector..

[StefThomas]

Hi, I tried this rapidly but didn’t find how to do so. Where/How do I do that ? Must unlink all the templates? Need to save the list first and then do all the links again? Stéphane THOMAS

A new version of the connectors will be out soon.

[StefThomas]

OK Thx. I’m trying it now.

Deactivate the connector get rid of the error message but my central seems not to be updated. Maybe I have another problem… I’ll wait and check after lunch :

The 19.04 to 20.04.12 was a piece of cake with absolutely no problem, the 19.04 to 20.04.13 is a nightmare :(

I hope you test your patch not only on a standalone platform.
