Centreon Infra Monitoring

Hi guys! do you have any specific instruction on how to configure a cloned poller? This would be very handy for indrastructure taht is distributed in multiple sites. It is also much more convenient to clone a VM than install everything from scratch. What I’ve learned so far:The usual suspects: IP, hostname , host SSH keys copy gorone config (from guil) and past it on the poller if it’s a new poller: configure engine for it on central if you replace an old poller: Gorgone history, mentioned in here This is probably sufficient for checks to run, but for exapmle platform status->poller statistics stays empty for cloned satellites. Anything else we need to know? Thanks in advance!

Hello, after a very hard update of a Centron 2.8 to a Centreon v. 24.04.5, it is no longer possible to login on the 24.04.5:I always get: “An error occurred during authentication”I tried to update the password in the database, but that didn’t work, in /var/log/centreon-web.log I see: [ERROR] [Core\Security\Authentication\Application\UseCase\Login\Login:166]: An error occurred during authentication {"trace":"Exception: Provider configuration with name local not found in /usr/share/centreon/src/Core/Security/ProviderConfiguration/Infrastructure/Repository/DbReadConfigurationRepository.php:324\nStack trace:\n#0 /usr/share/centreon/src/Core/Security/ProviderConfiguration/Infrastructure/Repository/DbReadConfigurationRepository.php(97): Core\\Security\\ProviderConfiguration\\Infrastructure\\Repository\\DbReadConfigurationRepository->loadConfigurationByType()\n#1 /usr/share/centreon/src/Core/Security/Authentication/Infrastructure/Provider/ProviderAuthenticationFactory.php(67): Core\\Securi

Hi,I’m using centreon since a lot of time on different projects for monitoring purposes. Now the customer asked me availability reports (the option is present) but i have for services, hosts and hosts group, 100% unknown.Looging at the logs on the eventReportBuilder.log i find error on scheduled launched command → 2024-08-08 03:00:03 - ERROR - MySQL error : cannot connect to database : Access denied for user 'centreon'@'localhost' Everything is working fine, RRD performance data are being stored and so on  but all the steps to create the availability view apparently fails.I also double checked the possibility to login as centreon user on the db and it works fine, any idea on what should I check? All my installations (made from scratch following the instructions)have this error. Kind regards

Bonjour la communauté,Nous souhaitons utiliser le modèle de service HTTP Collection pour interroger une API.Dans le tuto proposé (https://thewatch.centreon.com/product-how-to-21/http-collections-tutorial-how-to-monitor-an-api-2634), le format du payload utilisé pour la requête POST est json :"payload": { "type": "json", "value": { "security": { "credentials": { "login": "%(constants.username)", "password": "%(constants.password)" }}}}L'API que nous souhaitons interroger requiert un content-type "x-www-form-urlencoded".Exemple de requête généré avec Postmancurl --location 'https://xxx/services/auth/login' \--header 'Content-Type: application/x-www-form-urlencoded' \--data-urlencode 'username=***' \--data-urlencode 'password=***'Nous ne parvenons pas à paramétrer correctement le fichier json de la collection pour prendre en compte ce format d'appel.Quelqu’un aurait il déjà rencontré (et solutionné 😎 ) ce cas ?Merci à vous !

I am in the process of migrating my centreon 20.04 to 24.04 with the "awie" plugin.So I can export from 20.04 all services, hosts, controls, contacts... and import them (.zip format) into 24.04.I have a problem when I try to import all the services, the loading is infinite and only 53 services are downloaded (out of more than 1300).I tried to split the zip format to see where the problem could be. Sometimes the import succeeds, for example when I keep 8000/15000+ lines of code, but only the 53 services are loaded (I check on these lines, there should be about 574 services). I also have the same problem with the verification checks. All other elements are imported successfully. We also tried to restart pollers, services (cbd, centengine, gorgoned, centreon), reboot the server. Nothing changed. Thanks for you helping by advance, 

I have an old centreon version 18.10 running on a centos7. I want to migrate to debian12 version 24.04.I've followed the documentation (https://docs.centreon.com/docs/migrate/migrate-from-el-to-debian/) but during the upgrade process I get an error and it can't apply version 20.04.19 (see image). Nothing in the log files sql-error.log or upgrade.log as suggested.Any ideas?ThanksJean

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?
