Infra Monitoring Platform

Hi,We're interested in setting up multiple recurrent downtimes for hosts and services during our maintenance window. While the recurrent downtime configuration functions properly when linked with host groups, it doesn’t seem to work when linked with service groups. Here is our configuration : The service group is configured to Linked Host Group Services.In the Monitoring - Downtimes, we can view the history of recurrent downtime linked with host groups, but there's no information available for recurrent downtime linked

Good morning, we have a centreon-server with 8 CPUs and 32 GB of RAM and we monitor 975 hosts and 8600 services. We are having performance issues due to very high CPU usage and a very high load-average.Can anyone tell us if the hardware configuration is sufficient and what would be the optimal configuration for the centengine?Thank you

Hello everyone,I'm reaching out to you in desperation as I've encountered a critical issue with our Centreon 23 instance. By mistake, I've deleted our central poller, and since then, I've been facing enormous difficulties in recovering it.I attempted to recreate a localhost poller as a temporary measure, but unfortunately, it didn't work. The database seems intact (my hosts just no longer have any poller attached as a result); I haven't encountered any issues on that front.I also tried restarting services such as cbd, centengine, and gorgoned, but to no avail. The poller remains non-functional.I'm seeking your assistance in providing me with a detailed procedure on what to do when a central or local poller is accidentally deleted. Any help or advice would be greatly appreciated in this critical situation.My

Hello,I have an issue with API, I tried to list all host on my central with :<url_centreon>/centreon/api/index.php?action=action&object=centreon_clapiBody:{    "action": "show",    "object": "host"} I generate a token for my user, if I test it on my second central it works like a charm, but if I tried on my other central, I have an error 500 and I have no clue how to find the root cause.If I do a clapi request to list all hosts, it’s working.Any help to find what could going wrong would be appreciated. Thx

Hello,Our license expires in a few days, we are in the process of renewing it but we have not received the new license yet. What happens in Centreon when the license expires? Thanks,

Hi guys,I recently installed a fresh 23.10 version of Centreon, and I successfully migrated everything from my older 20.10 version. I have now every host and services on both sides, with a lot of services in an unknown or critical mode on the newest one.I understand that I have a lot to do with perl modules but that will be for a later post or later research on my own. My aim here is to either use or replace the old nagios check_http plugin, here is where i am at the moment :I tried to copy the old plugin to the newer version → two libs gives an error, even when I “create” them with symbolic link to my current versions of libcrypto.so.10 and libssl.so.10, the errors keep saying that they are not found So i tried to “update” my command with centreon commandsHere’s my old command :/usr/local/nagios/libexec/check_http -I 10.1.2.3 -u https://foo.bar.fr/some/path/somewhere -Sactua

Seeing some issues with 23.10.{9,10}.  I can’t delete services groups or even edit existing ones.  Basically after I confirm to delete, page goes blank and nothing was deleted.  This is holding me up from adding monitoring right now because I can’t create new service groups.I tried tailing logs, journalctl, everything in /var/log.  I see no errors when the page fails unfortunately.Actually, the most I’ve seen log wise which seems to correlate to when I get the failed page:mariadbd[6018]: 2024-03-05 23:01:31 35635 [Warning] Aborted connection 35635 to db: ‘centreon’ user: ‘centreon’ host: ‘localhost’ (Got an error reading communication packets)Any idea what this could be?  It seems to only be limited to Service Groups.Upgraded to the testing version.  No change.Acknowledging alerts seems broken as well.There is a host entry I deleted, yet still shows up in the resource list with service checks associated with it, even though I deleted the host.  Fee

Hello everyone,I'm reaching out to the community for some guidance on managing user permissions in Centreon. In our organization, we need to allow certain users (who should not have global admin rights) to be able to add, edit, and delete monitoring plugins in Centreon. The goal is to give them some autonomy in managing plugins without giving them full control over the system.I've looked through the documentation and configuration settings but haven't found a clear solution on how to set these specific permissions. Has anyone implemented a similar setup or can guide me on the best approach to this configuration?Here's what we're looking to achieve:The designated users should be able to add new monitoring plugins to the system. These users should also be able to modify the configurations of existing monitoring plugins. They should be able to delete monitoring plugins if needed. However, it's crucial that these permissions ar
