🇬🇧Hello,I’d like to monitor a few database files to track their growth and guide the developers. I started testing the CIFS plugin, but I can’t get accurate graphs for all the files in a folder. I finally found a syntax that works.​/usr/lib/centreon/plugins//centreon_protocol_cifs.pl --plugin=apps::protocols::cifs::plugin --mode=files-size --hostname='192.168.0.1' --cifs-username='DOMAIN/USER' --cifs-password='xxxxxxxxxxx' --timeout='' --file='/Depot/truc.1' --directory='/Depot' --max-depth='5' --warning-size='' --critical-size='' --verbose --file='/Depot/bidule.exe' --file='/Depot/machin.exe' --file='/Depot/Test.htm' --file='/Depot/chose.ps1'Listing all the files works, but obviously it doesn’t work if new files are added…So I have two questions:How can I monitor an entire folder without having to list every single file? Is that possible? How many files can I monitor without overloading the system? If I have 2,000 files, will Centreon go crazy trying to display all of them?When I

Hi everyone, I'm currently working with Centreon and the VMware 8 connector. I’ve successfully configured the ‘host-status' mode, but I’m running into a 401 Unauthorized error with other services. Has anyone encountered this specific issue with the new vSphere 8 integration? Any guidance on debugging the API authentication would be greatly appreciated.

Hello everyone, We updated our ESXi to version 8.So I'm trying to configure the new VSphere8 connector without success.I created a dedicated account on vCenter for monitoring.This account is functional since the "host-status" mode is working correctly:/usr/lib/centreon/plugins/centreon_vmware8_esx_restapi.pl --plugin=apps::vmware::vsphere8::esx::plugin --mode=host-status --hostname='vcenter.mycompany.fr' --port='443' --proto='https' --esx-id='host-1234' --username='supervision-centreon@vsphere.local' --password='XXXXXXXXXXXX' OK: Host 'esx1.mycompany.fr', id: 'host-1234': power state is POWERED_ON, connection state is CONNECTEDI can also connect to vCenter via the web and view the characteristics of my ESXi and VMs.I'm having a problem with all other services associated with this connector:/usr/lib/centreon/plugins/centreon_vmware8_esx_restapi.pl --plugin=apps::vmware::vsphere8::esx::plugin --mode=power --hostname='vcenter.mycompany.fr' --port='443' --proto='https' --esx-name='esx1.myc

Hello,I’m still trying to understand what happens, but I just upgrade from 24.10.14 to 24.10.15 and this is a disaster.All gorgone to Remote Server flux are downAll flux for Centreon Broken are down.  I’m still investigating , but i urge you to no upgrade your production setup and test it before on a stagging.

We are using a SSO solution to centralize our user authentication flows and because of that users have many many groups.When trying to login through Centreon, those groups data are added within the authentication token, making it reach huge sizes (around 4k characters for now), but the structure of the database on the table “security_authentication_tokens” for the “token” field is limited to 255 characters. i got explained that it is possible within an openid request to ask for a filter on the groups to maybe reduce that token size.Is there something to do in that sense and how can we do it ? This is blocking the deployment of this auth solution at scale.

Hi folks,Here my feedback/issue after go to 25.10Forced check doesn’t work anymore, success message after push it, but nothing happens When I create a new service, host, or modify anything, I have to restart all centreon stack : systemctl restart centengine to show up the new elements. Export config, restart engine from web is no longer enough Custom macros don’t work on service apply to hostgroup. (ok with linked on multiple hosts or host only)I migrate to a new platform (22.10 to 25.10) by following documentation ‘Migrate from an EL-type OS to another EL-type OS’ 

Hello,Since the update to Centreon 24.10.10, all my monitoring connectors appear greyed out in the Web UI. I can no longer update them or install new ones.I am now running 24.10.14, but the issue is still present.Here are the checks I have already performed: The fingerprint shown in the Web UI matches exactly the one stored on my server. The license type is correctly detected. I am well below the limit of 100 hosts (IT100 license). No hardware changes have been made. The issue appeared immediately after the 24.10.10 update and did not exist before. The 24.10.14 update did not fix the problem. Could you please tell me if this issue is known, or if there is a procedure to reactivate the monitoring connectors correctly?Thank you in advance for your help.Best regards,Florian

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 

Bonjour à toutes et tous,J’ai installé dernièrement un serveur avec Centreon pour superviser des serveur Windows (Windows Serveur 2019 DataCenter build 1809)La supervision avec le CMA en mode sans SSL fonctionne parfaitement,J’ai voulu passer en SSL et la plus de communication entre mes hôtes et le collecteur.J’ai fait le test avec un certificat autosigné et avec un certificat provenant de notre autorité de certification interne.J’ai sans doute loupé une étape. Merci de votre aide.

Hello everyone,Since migration (22.10 to 25.10) Graphs are no longer generated on Administration  >  Platform Status  > Engine Statistics.I’ve checkedpermissions:  /var/lib/centreon/nagios-perf/perfmon-1 : -rw-r--r-- 1 centreon-gorgone centreon-gorgonefiles : .rrd files are present, but don’t move since migration date /usr/sbin/centenginestats -c /etc/centreon-engine/centengine.cfg give stats no error in logsWhere is the problem ?    

Est-il possible d’utiliser le magasin d’autorités de certification Windows plutôt que de devoir spécifier un chemin vers un fichier de certificat en dur ?Les autorités de certification étant déjà déployées sur mes serveurs via des GPO, il serait pertinent de pouvoir s’appuyer sur ce mécanisme existant plutôt que de maintenir des fichiers séparés.  Is it possible to use the Windows Certification Authorities store instead of specifying a hard-coded path to a certificate file?Since the certification authorities are already deployed to my servers via Group Policy, it would make sense to leverage this existing mechanism rather than maintaining separate certificate files.

Hi everyone,I’m looking for the most efficient way to generate a list of active services (excluding templates) that do not have any contactgroup defined—neither directly nor inherited from templates.I’d like to explore different methods to achieve this, such as:SQL queries (directly querying the Centreon database) REST API (if applicable) Parsing configuration files (e.g., .conf files in /var/lib/centreon-engine/central/config/)If you’ve already tackled this issue or have any insights, I’d appreciate your input! Which method do you recommend for accuracy and simplicity?Thanks in advance for your help!

Hello, since a migration from the 24.10 platform to the 25.10 on a RHEL9 server (central server with the embed poller), after migration, most macros that were defined on the host don’t seem to be decrypted correctly by the poller.I’m seeing many logs like  fail to decrypt content of macro _HOSTCUSTOM_MACRO: Decryption finalization failed: error:1C800064:Provider routines::bad decryptI have followed correctly the upgrade steps from the documentation and especially for the poller to extract the symetric key at Upgrade from Centreon 24.10 | Centreon Documentation Does anyone face that issue yet ?

Hello Centreon Community/Support,I am experiencing an issue with a custom Lua stream connector script that is designed to send monitoring events to an external system (BEM). The script functions correctly on one Centreon Poller/Central server, but on a different host (which I'll refer to as "Problem Host"), events are consistently being dropped at the filter stage, resulting in the debug log message filter' returned false.I have confirmed that the target system is listening on the expected port (2540) and that the "Problem Host" can establish a TCP connection to it.Problem Description:On a specific Centreon host (the "Problem Host"), the Centreon Broker Lua stream connector is not processing events as expected. The debug logs show that the filter function in the Lua script is rejecting all incoming service status and host status events, even though the same script works perfectly on another Centreon host. This prevents any alarm messages from being sent to the BEM system.Observed Debug

Hello everyone,We are monitoring a Vcenter v8 cluster, and all was fine with Centreon 22 (so using the sdk file).Since upgrade to Centreon 25.10, connector is not working anymore. I saw that now there is a JSON file instead of the PM one (file is deprecated).I used the configurator to add my Vcenter, and I can see the JSON file filled with the informations (server ip address and login/pwd stored in crypted mode). As I understand, Centreon 25 is now storing credentials in crypted mode.Issue I’m facing is:I believe that the Vcenter platform is receiving the user credentials in crypted mode so I got a “user failed connection”. I looked in the vcenter log files for this. so the Vcenter is not able to authenticate as user is crypted and unknown for him. Is there a way to fix this ? I know that the restAPI plugin is designed for Vcenter8, but could we monitor all the same functionalities as the vmware_centreon plugin ? Many thanks for your replies,  Antoni

Hello, I upgraded to version 25.10 and now the centreon_linux_snmp.pl plugin only works for certain checks, such as load mode and swap mode. However, it no longer works with CPU, storage, RAM and memory modes, even though nothing has changed.Furthermore, when I run the command on my poller in CLI, it works, but when I run it from the web interface, I get an ‘execute command failed’ error, even though I have the correct permissions, etc. I really don't understand.Need help, please. 

Bonjour, Maintenant que j’arrive à faire communiquer correctement mon poller avec quelques clients CMA, je n’arrive toujours pas à superviser les services windows.  J’ai mon service qui est correctement nommé dans le FILTERNAME mais Centreon m’indique le message suivant : Est-ce que vous auriez une idée d’où je me serais trompé niveau configuration? Merci
