Hi,Following the migration of our Centreon server from Alma 9 to Debian 12, we are experiencing consistent timeout issues when monitoring a Windows VM and a storage array.The Windows VM has refused to respond correctly to requests since the migration:NRPE (Job-Status): The NRPE version ping works remotely (‘I (0.11.8 2026-01-24) seem to be doing fine...’), but as soon as I call a script, I get a ‘Process Timeout’ (and ‘0 bytes received’ in the CLI).

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.

Why this appear in command line ? Is there any solution to show command line or  correct this ?

Hello,I have just installed CMA 24.10.16 on Windows and configured a service to monitor a wildcard SSL certificate.For one specific certificate, CMA appears to crash and no metrics are sent to the poller.In the Windows Event Log, I can see the following error:[2026-06-19 12:00:15.102] [error] [wire_format_lite.cc:610] String field 'opentelemetry.proto.metrics.v1.Metric.name' contains invalid UTF-8 data when serializing a protocol buffer. Use the 'bytes' type if you intend to send raw bytes.The issue seems to be related to the certificate subject, which contains accented characters. The certificate CN/Subject includes:S=Côte-d'Or, C=FRWhen this certificate is checked, CMA stops sending data to the poller. Other certificates without accented characters do not appear to trigger the issue.Could you please confirm whether this is a known issue with UTF-8 handling in CMA 24.10.16 and advise on a possible workaround or fix?Please let me know if you need any additional logs or configuration de

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

Hello,Is anyone else facing this kind of issue?A map in a custom view or a dashboard is randomly displayed as the map or the map homepage (the page listing all maps).If the page is refreshed, the map is correctly displayed but not all the time.

I can’t test with firefox.the problem appears after updating to 24.10.23Thanks
