HelloI’ve set-up CMA on my central + poller + an agent.In centreon, I’m unable to select host template “ OS-Linux-Centreon-Monitoring-Agent[-custom] “ template. I can see them in host templates and edit the -custom one.They just don’t appear in the host template selection list

Hello, just here to share to the community an issue that i encountered, the underlying issue, and how it can be resovled.This happened on a quite heavily loaded central server (poller included), and my end users reported receiving load of emails alerts regularly, but during bursts of a few minutes.After investigating the commands failing, there was nothing to correleate them, any service could fail, and all failed with the same output: “Execute command failed”. Something strange was at work here.After going more in the logs, especially centreon-engine logs, i find it. “Too many open files”. Here is the issue.At first i supposed there was permissions issues or something, but this is irrelevent as all can happend to any commands usually working fine. So i dig deeper on the internet, and here i find it, the Linux File Descriptor Limit. cyberciti.biz - linux increase the maximum number of open files . This limit by default is around 1024. I then do a quickls /proc/[centengine_pid]/fs/*and

Hi,I don’t know if it changed recently or if it has always be like that, but I noticed the following: if --expected-content has a value, then --critical-content is ignored. It means, if one want to check both a return code and the presence of a string in the page content, one should not use --critical-content=’ %{code} != 200 and %{code} != 401’ --expected-string=foo (because then only the presence of “foo” would be checked!), but what must be used is  --critical-content=’ %{code} != 200 and %{code} != 401 or %{content} !~ /foo/mi’.Is it something that changed recently? Is this something reliable (ie: it won’t change in the futur) ? 

Hello, one of my clients has reported that they are having trouble accessing their Centreon platform in production following an automatic version update on their server.How can this feature be disabled in Centreon?Thank you for your help

Hello.Is there a plugin that can be used to get the DNS zone expiration from SOA?I have tried with the DNS Service connector, using --mode=request --search-type='SOA' but it doesn’t show the complete SOA. With --verbose or --debug the result is the same, only the response time.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 ?

We are experiencing an issue after upgrading Centreon to the latest version. We recently upgraded our Centreon platform to the latest version 24.10.27 and have observed an issue affecting multiple monitored serviceSince the upgrade, several services that were previously working correctly are now reporting an UNKNOWN status.The plugin output reported for the affected services is: - UNKNOWN: No locks counter found with given filters- UNKNOWN: No locks waits counter found with given filtersWe would like to understand if:- There are any known issues after upgrading Centreon that could cause services to return UNKNOWN status.- Any plugin changes or compatibility issues introduced in recent Centreon versions could explain this behavior.- There are any known fixes or troubleshooting recommendations for similar cases. Any guidance or suggestions would be greatly appreciated.

Hello users and maybe Centreon team.I was having a thought.Now that there is a multiple ecosystems around Centreon like Centreon Experience or Log management, there is a component called User Portal to manage common configurations between services.This makes a lot of sense, but here is something that confuses me.Right now within Centreon if you want to create dashboards about coordinated data, you need to extract partial data from those tools to Centreon Infrastructure Monitoring (so they can be historised) and then within that tool create dashboards.Wouldn’t it make sense to have some kind of Historisation / Dashboarding solution on TOP of all the existing components ? I suppose that’s for historical reasons (as all started from that component), but as the ecosystem evolve i’m questionning myself. This is close (in my opinion) to what is intended behind the BAM module where we aggregate multiple technical sources to give business views, but having to do that within the Centreon Infra

Hi,We are starting to look at the new version of Centreon (25.10.10) and would like to set up some custom views.Looking online. I can see that Custom views are hidden by default, and that there is a manual process to enable them, but I can’t find out what that process is.Can anyone help?Thanks,alamb200

Hi Everyone,Is there anyone encounter the same issue with us? We set 5:30AM to 7:30AM PH Time but it reflects in Centreon is 11:30 AM to 1:30 PM. Is the new version (24.10.16) is based on the local time zone of the sever not the user profile timezone? My timezone set in Centreon GUI is set to Asia/Manila.Server timezone/ Central Server - Europe/Amsterdam.Thank you!

Bonjour,Tous les matin vers 2h, nos pollers se figent.Nous avons constaté qu’il y des taches CRON qui tournent à 2h du matin et 4h du matin sur le central.Lorsqu’on fait un kill des deux CRON, tous revient à la normale, soit redémarrer le central.

Hello,I have configured the Centreon Monitoring Agent (CMA) for my Windows server.However, when I try to create a host in Centreon and assign the host template OS-Windows-Centreon-Monitoring-Agent-custom, this template does not appear in the host creation form.The template is present and visible in Configuration > Hosts > Templates, but it is not available in the template selection list when creating or editing a host.I am using Centreon 24.10.26 and I do not have a commercial license installed.Has anyone encountered this issue before or knows why this template is not available for host assignment?Thank you for your help.

Hi,Is it possible via API to get a service macro field value via the v2 API? 

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 ?

in my environment i also use passive checks, some tests results submitted once a week or month.with one of the latest centreon version (in mycase Centreon 25.10.14) passive checks also gets down if host check fails and stays in this state until next passive test result.i’m using activated “Disable Service Checks When Host Down”with older centreon versions the passive checks weren’t changed if a hosts get down and you use this option (only the active ones).I’m not sure with what version this behavior changed, it think with 24.10 it worked like before
