I don’t know why I can’t edit my previous message. 

Just checked if ZMQ::Constants was installed

And, yeah, ZMQ is already installed. 

Any tips ?

Hi,

I’ve the same issue … and i’ve ZMQ::Constants 1.04

Regards

Hi,

I just switched to Centos7 and the problem was solved. I don’t know why this problem occured on Oracle 

Hello guys,

We have the same issue on our RHEL 9 machine:

[root@centreon ~]# cpan ZMQ::CONSTANTS
Loading internal logger. Log::Log4perl recommended for better logging
Reading '/root/.cpan/Metadata'
  Database was generated on Tue, 20 Jun 2023 06:17:02 GMT

>(info): and you provide the -x option on invocation.
>(error): Skipping ZMQ::CONSTANTS because I couldn't find a matching namespace.
>root@lscentreon ~]# instmodsh

We need help here, because we can’t just downgrade to RHEL/CentOS 7.

Hi all, sorry for that, and for my late answer.

According to me it has been fixed a while ago, and my tests show that it’s OK now.

Can you confirm?

I have a similar error. ZMQ Constants is installed. 

Status information

UNKNOWN: Cannot load module --custommode.

Can't load '/usr/lib64/perl5/vendor_perl/auto/ZMQ/LibZMQ4/LibZMQ4.so' for module ZMQ::LibZMQ4: libperl.so.5.36: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou dossier de ce type at /usr/share/perl5/XSLoader.pm line 96.

Any help please? i dont have access to the internet from my environment. I am searching in the downloads for the right package but cannot progress.

Hi!

We are working on this issue. The fix will be released as soon as possible.

Hi @omercier ,

I have the same kind of issue when I want to supervise a VMWare ESX :

Centreon 24.04 runs on Debian Bookworm.

I tried to install ZMQ with packets, everything seems good until the following error appear :

Thanks in advance.

Alors, d’après mes petites recherches concernant l’erreur de module ZMQ sur Centreon 24.04 sous Debian Bookworm :

Il faut installer les outils de développements nécessaires au traitement du module perl ZMQ :

apt-get install build-essential

Puis installer ‘cpanminus’  pour installer les modules perl, car ‘cpan’ peut rencontrer des problèmes lors des installations :

apt-get install cpanminus

cpanm ZMQ::Constants

(Si ‘cpanm’ ne fonctionne pas non plus voici les commandes pour installer les modules manuellement :

wget http://search.cpan.org/CPAN/authors/id/D/DM/DMKAI/ZMQ-Constants-1.04.tar.gz tar -xzvf ZMQ-Constants-1.04.tar.gz cd ZMQ-Constants-1.04 perl Makefile.PL make make install

)

Vérifiez que les modules se soient bien installé en demandant à voir la version de ces derniers :

perl -MZMQ::Constants -e 'print $ZMQ::Constants::VERSION'

L’output va se lier avec le pwd, donc c’est bizarre, mais ça fonctionne bien, ‘1.04’ est la version :

Enfin, redémarrer les services Centreon :
systemctl restart centreon

Pour ma part, ceci n’a pas suffit, j’ai dû installer le module ‘ZMQ:LibZMQ3’ en plus :

cpanm ZMQ::LibZMQ3

Vérification de la version :

perl -MZMQ::LibZMQ3 -e 'print $ZMQ::LibZMQ3::VERSION'

Redémarrage des services Centreon :

systemctl restart centreon

Pour ma part, les erreurs sont passées de ‘UNKNOWN : Cannot load module’ à ‘ UNKNOWN: Cannot get response (timeout received) ‘

Je suppose qu’il y a du mieux :)

​ENGLISH

After some researches about ZMQ module’s error on Centreon 24.04 under Debian Bookworm :

You seems have to install development tools needed to process perl module ZMQ

apt-get install build-essential

Then install ‘cpanminus’ to be able to install perl modules, because ‘cpan’ can face some issues while installing those :

apt-get install cpanminus

cpanm ZMQ::Constants

(If ‘cpanm’ does not work either, here is the command lines to install modules manually :

wget http://search.cpan.org/CPAN/authors/id/D/DM/DMKAI/ZMQ-Constants-1.04.tar.gz

tar -xzvf ZMQ-Constants-1.04.tar.gz

cd ZMQ-Constants-1.04

perl Makefile.PL

make

make install

)

Check the modules are well installed by printing their version :

perl -MZMQ::Constants -e 'print $ZMQ::Constants::VERSION'

The output will merge with the pwd, it’s weird, but it works. ‘1.04’ is the version :

Finally, restart Centreon services :
systemctl restart centreon

For me, this was not enough, I had to install ‘ZMQ:LibZMQ3’ module :

cpanm ZMQ::LibZMQ3

Checking version :

perl -MZMQ::LibZMQ3 -e 'print $ZMQ::LibZMQ3::VERSION'

Restarting Centreon services :

systemctl restart centreon

For me, errors went from ‘UKNOWN : Cannot load module’ to ‘UNKNOWN : Cannot get response (timeout received)’

It’s better I suppose :)
