Centreon Infra Monitoring

Hello,We are using Centreon 2.5.4 (cbd, nagios,etc...) and the various servers are running Centos 6.11.We have a central server, several poller servers and a mysql server.We encountered a problem with our VMs and had to restore them from a snapshot.Since then, we've been unable to start the cbd service (/etc/init.d/cbd) on the poller servers. They start, but after a synchonization with the central server, it ends up stopping after a 60s timeout with the following error:  error: TCP: error while writing: Socket is not connected On the central server, the cbd service is running fine.Do you have any idea why this error occurred? Best regards,Kevin Pemonon

Hello, i want to use an opensource version of CENTREON, but is there any limitation with the number of host or metrics ?

Bonjour,Je ne parviens plus à afficher plusieurs ligne dans le ‘Status Information’ de me services.Avant j’envoyais depuis un script perl :print “Resultat a afficher:<br> informations à afficher\n”; Ca affichait bien sur 2 lignes (Grace au <br>):Resultat a afficher:informations à afficher Or maintenant ca affiche :   Resultat a afficher:<br> informations à afficher Le saut de ligne HTML <br> ne semble plus marcher …. et j’ai ressayé plusieurs variantes: \r ou \n .. mais rien à faire…Une idée ?

Bonjour,J’installe un nouveau serveur en suivant la documentation pas à pas et lors de l’installation du central (avec bdd), le dnf install centreon install le paquet mariadb-server (qui est en 10.3) alors que la 22.10 nécessite maraidb 10.5 (qui est reconnu avec le paquet MariaDB-server et pas mariadb-server). Est-ce que je dois installer d’abord mariadb en 10.5 ou installer mariadb en 10.3 puis faire le saut 10.3 > 10.5 ou corriger les dépendances de l’application centreon ? Cdlt,

Bonjour, Nous avons migré notre solutions Centreon il y a quelques temps déjà d’une version obsolète à la dernière version stable.Tout fonctionne correctement dans l’ensemble mais nous rencontrons quelques problématiques.En effet, certains hôtes/services semblent bugués après import et ceux ci ne prennent pas en compte les modifications.Y’a il une façon de nettoyer/vérifier la base de données ou y’a il des endroits où je peux vérifier afin de trouver l’origine de l’anomalie ? Merci d’avance 

It's been 5 months now since we released Centreon 23.10. If you have not adopted this version yet, please check the Product Updates article for more details.

Bonjour à tous,Nous mettons en place plusieurs check CENTREON avec des scripts Externes Powershell.Le dernier en date me pose problème et je ne sais pas où chercher.Quand il est exécuté via un compte admin local ou admin du domaine, tout fonctionne correctement.Cependant, lorsque je l’exécute avec NRPE3, j’ai un bout de code qui ne réagi pas normalement.Le script fait :Récupération de la dateRécupération de la taille d’un fichierExport CSV dans un tableau avec colonne SIZE et DATE.Après, calcule pour vérifier si le fichier a grossi + pourcentage associé.Mon problème est dans l’export.Lancement du script depuis le serveur avec un compte admin local ou admin du domaine, j’ai bien la taille et la date.Mais avec NRPE3, la date ne s’inscrit pas dans le fichier CSV.Quelle différence il y a t il entre les 2 exécutions pour avoir ces 2 résultats ? Merci de votre aide !

Hello,I am monitoring a Windows server with NSClient++ RestAPI, and the "Services-Auto" service reports: GoogleUpdaterInternalService124.0.6337.0=stopped (auto), GoogleUpdaterService124.0.6337.0=stopped (auto)I want to exclude them, but the issue is that each time they are updated, the version number increases, and the name changes.I tried to make an exclusion with a wildcard based on what I found here and there, but it doesn't work.Is it possible to make an exclusion with a wildcard? If so, what is the correct syntax?Thanks in advance.

I’m trying to use host discovery as per:  https://docs.centreon.com/docs/monitoring/discovery/hosts-discovery/(with the Generic SNMP host discovery provider) Unfortunately, neither “execute immediately” nor scheduled jobs seem to ever progress from ‘scheduled’ to ‘running’ - the host discovery UI has them indefinitely stuck at ‘scheduled’, 0s duration, 0 hosts discovered, “execute now” and “show results” greyed out.What could I be missing?
