Bonjour,Is there a way to manage/show the links between hosts/services and  contact/contactgroup with the REST API.I don t see anything in the official documentation, in the host, service, contact, contactgroup part.Thanks for reading and answering,Mathias   

Hello there,I am having an issue getting the right value printed on my graph.I have created a meta service that calculates the sum of two other integer values.In my output, I get the right result, like: → OK: sum = 443And the perf data also: → 'g[value]'=443.00;;;;But in the printed curve of the graph, I don't get the exact values; instead, I get values with decimals like 441.82, 440.61, etc.Any ideas?Thank you. 

Hello,I am using Centreon DSM and I have noticed that when I acknowledge a slot, the slot executes it’s check command and pass into OK status, so I checked centengine.log file and I have found that two command were executed (acknowledge and force_check ), so am asking if there is a way to disable the force check when acknowledge an alert from the resources status page.We have the possibility to enable/disable a force_check in the old interface, but not in the new interface. Acknowledge: Resources status (no option to disable force_check) Acknowledge: Status Details → Services (with option to disable/enable force_check) centengine.log file[1682693066] [1000] EXTERNAL COMMAND: ACKNOWLEDGE_SVC_PROBLEM;linux-1;SnmpGatewayTraps_0002;2;0;1;admin;Acknowledged by admin[1682693066] [1000] EXTERNAL COMMAND: SCHEDULE_FORCED_SVC_CHECK;linux-1;SnmpGatewayTraps_0002;1682693064  Centreon 21.10 Thanks.Best regards.

Hi everyone,I discovered this morning that I could customize my login portal on version 23.10.Then, I upgraded to V24.04 and I cannot customize it anymore.I refreshed my plugin, but I still can't customize it. If someone has an idea, please let me know.Administration > Customize Centreon

Hello.We are trying to use the executable file of the plugin centreon_plugins.exe (https://github.com/centreon/centreon-nsclient-build/releases/tag/20240711) on Windows Server 2022 together with the Icinga 2 for Windows agent. And we have a problem with this.If we manually run cmd.exe as administrator and execute the command to call centreon_plugins.exe there, it works successfully:C:\ProgramData\icinga2\plugins\centreon_plugins\centreon_plugins.exe --plugin os::windows::local::plugin --mode pending-rebootOK: 'Microsoft Windows Server 2022 Standard': reboot pending is false [Windows Update: false][Component Based Servicing: false][SCCM Client: false][File Rename Operations: false][Computer Name Change: false]The Icinga 2 for Windows agent service runs on behalf of Local System. Therefore, we try to run cmd.exe on behalf of Local System and execute the same command there. And it works successfully again.But if we try to call the plugin via the Icinga 2 for Windows agent, we get the mess

Hello team, I need help in clearing the mail queue in one of our Centreon pollers. For some reason we have hundreds of old/stale mails in the queue. I use the command “mailq” to see all these old emails in the queue. I need to clear or delete these old emails from the queue, but I am not sure in which folder or directory to check and clear this...also can please advise the correct comment to delete this? Thank you,Crisanto

Hello,i have a centreon server version 2.8.26, now I want to upgrade to the newest version? Is this directly possible, which instructions should I follow?

Hi,Just upgraded a plateforme to 23.10.14 a few days ago and I noticed all the monitoring connector packs were no more  marked as installed in the manager (although all centreon-pack-* packages are present). This looks like a bug but it’s not the most surprising thing. When I went for reinstall the packs I noticed very strange dependencies, like, for example, when I installed “Generic SNMP” it installed “Mac SNMP” and “FreeBSD SNMP” (at least). If I try then to remove “Mac SNMP” it confirms the dependency:  Same with “FreeBSD SNMP”. What’s the problem? I can perfectly understand how it may exist a dependency on “Generic SNMP” for the Mac and FreeBSD packs, but not the other way around.I guess I should remove the RPM for those packs (I’ll test if I find some time later) but it still doesn’t look right to me.

How to remove downtime once set. Suppose if i set a fixed downtime and want to cancel in middle. How should i do it ?

After upgradind centreon from 21.10 to 22.10.2, I ‘ve got an error in the web interface (and when I execute the command directrly from the server)How can I solve this error?Thanks for your help

I imagine this question has been asked before.I am looking to calculate the volume of traffic for a monitoring probe/plugin.The goal is to estimate the cost if my poller were based on Azure to monitor on-site objects.

Hi! Is there a clever way to negate the ACLs?A little background: We use Centreon as umbrella monitoring for many different applications. As the IT departmentt is quite big, there are several teams with specific focus. The main crew just cannot help with some of the problems as they are too specific, so a team, i e. ERP crew,  needs to react on the Centreon warnings. We actually can add these services to specific host groups or service groups and use ACLs to show the specific teams. So far so good, but they still appear in the views of the main crew. Of course, we can create an ACL for “all others” and present this to the main crew, but we are afraid that someone will add a service to monitor and forget this setting. The monitored host or service will then be simply invisible. A good solution would be a way to negate the ACL, i.e: resource ACL “hostgroup NOT ERP”.  Any suggestions?

Hello everyone,I'm going from one problem to another and the latest is when I export my configuration.I have a service which, even if I remove it or rename it in the /var/cache/centreon/config/engine1/serviceTemplates.cfg file, comes back every time. And this duplication blocks the export.I've searched the resource.cfg, and I don't see why this service, the PING, is repeated. Is there a “hard” place where it's written to be parsed afterwards?  define service { name PING check_command OS-Linux-SNMP-Tcpcon!100.0,20%!500.0,60% check_period 24x7 max_check_attempts 3 check_interval 10 retry_interval 2 register 1 use local-service}define service { name Balloning memory check_command OS-Linux-SNMP-Traffic-Name!1!10 check_period 24x7 max_check_att

I added the OS-Linux-Mountpoint-SSH-custom service template to my Linux hosts, but some give errors because there are ramfs partitions mounted with the ro flag.To avoid these errors I would like to add the ramfs (next to the squashfs and tmpfs) type to the types to exclude in the critical treshold (which by default is '%{options} !~ /^rw/i && %{type} !~ /tmpfs|squashfs/i').How can I do that? Obviously completely ignoring ramfs would also be an option.
