Infra Monitoring Data collection

Good afternoon, Our Centreon has been installed on AlmaLinux 9.8.Every control is working but the ones directed to the IBM i.We are using an external plug-in (M81’s Control4i).The control is working just fine and giving feedback when executed from the Linux VM.But when the controls are set up on the Centreon GUI, the commands do not give any output “(Execute command fail)”.Also, in the /var/log/centreon-engine/centengine.log file, there are messages that indicate that the connection between Centreon and the target IBM i is not done, while it works perfectly when launched from the VM.  Here are the messages : In the beginning (occurring 17 times on a row) : [2026-08-28T15:14:49.453+02:00] [otl] [error] [204282] fail to force check : No agent that checks service xx of host 1 connectedand then (occurring n times) : [2026-08-28T15:14:55.757+02:00] [otl] [error] [204282] 0x3a61820 reverse_client fail read from xxx.xxx.xxx.xxx:4317[2026-08-28T15:14:55.757+02:00] [otl] [error] [204282] 0x3a61

HelloIt seems the centreon_storage.data_bin table is not used anymore by centreon, as this table does not exist anymore.Although, partitions of this table are still present, and deletion of these partitions + restart of mariadb leads to a broken centreon web frontend. Il there a clean way to get rid of this data_bin old data, which uses about 300G of disk space on my installation ? Regards

Hi guys,I need Help to change data collection from poolers.I mean in my configuration all poolers should communicate with the main Centreon Engine 23.04.4 via VIP address. But for some poolers after a reboot of main Centreon server they are sending data directly to Centreon servers without passing through the VIP and until now I didn’t find how or where to force the pooler to communicate only with the VIP.Can you please help me in this case ?

Hello,I was wondering why there is so many differences between the NRPE for Debian and for RedHat, Debian user : centreon-engine (?!)RedHat user : nrpe Debian config : /etc/nrpe/centreon-nrpe4.cfgRedHat config :/etc/nagios/nrpe.cfgBy default, the only difference between these disto are the user used to run the binaryRedHat : nrpeDebian : nagiosTheses new inconsistencies are painful to manage, perhaps the Debian package build by Centreon can set the same user as under RedHat The last thing I don’t understand is why you asked to add this repository for Debian https://packages.sury.org/php Which template needs PHP on a remote server monitored via NRPE ? 

Hi!I’m trying to follow the tutorialto implement monitoring of SAP SCC. Two issues:HTTP basic authentication: it’s not clear from the tutorial how to get a plain simple HTTP basic auth. Took me hour to figure out (use the source, Luke!) that you just need to pass ‘basic’ like this: "authorization": {"basic": 1,"username": "%(constants.username)","password": "%(constants.password)"}, I would add it to the original post, but the comments are locked. Please add it, so people save a lot of time. Path depth. SAP will respond with a JSON of this type: { "subaccounts": [ { "description": "SAP BAS", "displayName": "SAP BAS", "tunnel": { "state": "Connected", "connectedSinceTimeStamp": 1720773876375, "connections": 0, "applicationConnections": [], "serviceChannels": [], "subaccountCertificate": { "notAfterTimeStamp": 1749540416000, "notBeforeTimeStamp": 1718000816000, "subjectDN": "CN=B0CADA20E31311EBBF8AD

Hello,I am using a homemade service template similar to  App-Protocol-HTTP-Json-Content to get information from a database and value the number of users connected to a wireless network profil / SSID. I am confused by the range definition which seems not demonstrating what the following documentations annouce :https://docs.centreon.com/fr/docs/monitoring/metrics/ https://nagios-plugins.org/doc/guidelines.html#THRESHOLDFORMAT I want the service to be in WARNING state if element_1 = 0, and CRITICAL if element_1 < 40. Starting with the WARNING, here are my test results (for the purpose of the test I am replacing 0 and 40 by the output of the service the simulate and NOK case) :Definition or range for WARNING seems ok sometimes, nok others : [centreon-engine@mypoller ~]$ /usr/lib/centreon/plugins/centreon_protocol_http.pl --plugin=apps::protocols::http::plugin --mode=json-content --hostname=[Hostname] --proto='https' --port='8181' --cacert-file='/etc/pki/tls/certs/ca-bundle.crt' --urlp

Hi,Since the NSClient++ project has been on a long break (from april 2018 and november 2023) we have never included its releases in our continuous integration processes. But since then, the project show an impressive level of activity.As we have been very busy doig a lot of other things, we have fallen far behind on this updating the base version of NSClient++ used for our builds.We’re currently trying to bridge this gap and given the wide number of changes, we may expect some regressions.Please feel welcome to use this pre-release and give us feedback here!Here are the known issues (I’ll update them as they’ll be found):The old authentication (using --legacy-password and no login) does not seem to work anymore. Since it’s not a good practice, you’re invited to switch to  --username and --password. NB: the apps::nsclient::restapi::plugin needs this commit to handle this authentication process.

Bonjour,Je viens de migrer mon centreon 22.10 vers 25.10 centos7 vers Debian12. Tout est parfaitement fonctionnel mis à part les macros des services par groupe d’hôtes qui ne sont plus interprétées et non présentes dans le fichier /etc/centreon-engine/services.cfgEn revanche les macros des services par hôtes et les macros d’hôtes sont elles bien interprétées et présentes dans les fichiers de config.Est ce qu’il y a un changement dans la prise en charge de ses macros ?J’ai essayé de passer par des templates pour mettre les macros mais comme se sont des templates lées à des services de groupes d’hôtes le résultat est le même. Merci pour vos retours
