Centreon Infra Monitoring

Bonjour à tous,Après m’être lancé en vain dans une tentative d’installation de Centreon, en utilisant les packages sources au format tar.gz à cause de le particularité de notre SI (pas d’accès direct à internet et installation dans des dossiers spécifiques)  [→  topic ].Je suis reparti sur une nouvelle installation de la version 21.10 avec les packages au format rpm, toujours dans le même contexte, mais en jouant avec des liens symboliques pour les répertoires spécifiques... Cette fois-ci, l’installation est plus simple & rapide et va arrive sans souci à son terme.Mon infrastructure est installée et opérationnelle: 1 serveur web, 1 serveur BDD, 1 serveur poller. J’essaie aujourd’hui de reproduire ce que nous avons actuellement en production avec une version plus ancienne (19.04):La très grosse majorité de nos checks sont des checks passifs. Notre infrastructure supervise un très grand nombre de serveurs et donc de services. Pour répartir la charge en entrée sur nos pollers, nous av

Hello, I recently installed a new server (windows 2016), and I simply can’t install Centreon NSClient, the install button remain greyed out (i’m running it as admin and can button isnt greyed out on another 2016 server) I was perfectly able to install it on other 2016 servers with the same installer.

Hi there I have a problem with Centreon MAP desktop client, when I synchronise resources, I have this error : Resource synchronization has crashedIn the log on the server, I have :[2022-04-21 16:44:24.995] [ERROR] [c.c.s.m.s.b.s.impl.CentreonSynchronizer] [StudioScheduledTask-7] : Error while running CentreonSynchronizerorg.springframework.orm.jpa.JpaSystemException: More than one row with the given identifier was found: 4278, for class: com.centreon.studio.map.server.dao.centreon.entity.ExtendedServiceInformation; nested exception is org.hibernate.HibernateException: More than one row with the given identifier was found: 4278, for class: com.centreon.studio.map.server.dao.centreon.entity.ExtendedServiceInformationAny idea?Thanks!

Hi, We have a Centreon 20.04.3 working like a charm for several months and years.But, since about 10 days, we can no more update and apply changes in monitoring.More precisely, when :creating a new service for an existing host, and exporting to all servers, conf is OK but monitoring is not refreshed/applied, modifying an existing service, with just a change (IP, ...), and exporting : same thing. Conf OK but monitoring is not updated.Of course, central, sat, etc… have been rebooted… No changes.We are not able to know what action we have done, which could create our problem. We have deleted 10 or 15 days from now, one host, but not attached services. So we have now services we cannot update/view because of lack of their host. But not sure that is connected to our problem.We do not know where to investigate… Any idea ? PS : Our Centreon is clustered : one Mysql server, one central, and 6 sat.

Hi,I am currently monitoring a QNAP NAS with SNMP, and i wasn’t really satisfied with the way the QNAP plugin handled the data and i had compatibility issues with some of the functions so i decided to make my own checks for the memory utilisation.Here’s my issue :Basically, when i ask for the amount of free memory on my NAS with a get-snmp request, i get this value :This is exactly what i want on Centreon since i can display this on a graph.However, when i use the generic-snmp plugin with the same parameters, i get this…It seems that the plugin interprets the result as “ok” without giving me the actual value. Using the --verbose flag doesn’t change the result either.How do i formulate the snmp command to get a proper value? Here’s the syntax i use right now :perl centreon_generic_snmp.pl --plugin apps::protocols::snmp::plugin --mode string-value --hostname “IP” --snmp-version 3 --snmp-username ‘username’ --authpassphrase 'passphrase' --authprotocol MD5 --oid .1.3.6.1.4.1.24681.1.2.3.0T
