Centreon Infra Monitoring

Hello everyone,We are monitoring a Vcenter v8 cluster, and all was fine with Centreon 22 (so using the sdk file).Since upgrade to Centreon 25.10, connector is not working anymore. I saw that now there is a JSON file instead of the PM one (file is deprecated).I used the configurator to add my Vcenter, and I can see the JSON file filled with the informations (server ip address and login/pwd stored in crypted mode). As I understand, Centreon 25 is now storing credentials in crypted mode.Issue I’m facing is:I believe that the Vcenter platform is receiving the user credentials in crypted mode so I got a “user failed connection”. I looked in the vcenter log files for this. so the Vcenter is not able to authenticate as user is crypted and unknown for him. Is there a way to fix this ? I know that the restAPI plugin is designed for Vcenter8, but could we monitor all the same functionalities as the vmware_centreon plugin ? Many thanks for your replies,  Antoni

Hello, I upgraded to version 25.10 and now the centreon_linux_snmp.pl plugin only works for certain checks, such as load mode and swap mode. However, it no longer works with CPU, storage, RAM and memory modes, even though nothing has changed.Furthermore, when I run the command on my poller in CLI, it works, but when I run it from the web interface, I get an ‘execute command failed’ error, even though I have the correct permissions, etc. I really don't understand.Need help, please. 

Hello,I’ve got two VMs to monitor with Centreon. For the first one, I'm using a plugin from Centreon’s GitHub repo centreon-plugins/src/centreon_plugins.pl at develop · centreon/centreon-plugins (github.com)  plugin-path: src/centreon_plugins.pl  For the second VM, I would like to use an RPM instead of pulling the plugin from GitHub.Do you know how I can find the equivalent RPM? Any keywords I should be searching for? Have you used RPMs instead of the GitHub plugins before? Thanks for the help!

With the new, extremely short lifecycle for STS versions (odd-numbered years), have those with only 18 months of support become beta tester versions ?I find this lifecycle choice very surprising.Why does support for STS versions end before the following LTS version is stable and completes its Phase 1 ?Today, if I want to stay on a stable version, I must stay on 24.10 until October 2027, and only then can I double-jump from 24.10 to 26.10, even though 25.10 will no longer be supported.If I upgrade to version 25.10, I'll be forced to upgrade to 26.10, even though it won't be stable yet.I get the impression that these STS versions, like 25.10, offer neither new content nor stability in the short, medium, or long term.I preferred the old cycle.Or at least, in my opinion, it would be better to extend the STS to 24 months.Am I wrong? Have I misunderstood the improvements in this new cycle ? Thanks

Hi, I want to check the alerts already defined in prometheus without to use the query mode. Because it is easier for us to define the treshold. Is there a way to ask the result of the alert defined in prometheus withtout ? I have try with the plugins but it doesn’t work.For exemple, If i use the name AlertmanagerFailedReload for this alert :   

Hello,Since upgrade to 25.10, we are facing a weird issue on Host adress form.While in 23.04 this field was most likely “open to any format”, it now requires a “valid IP / FQDN Format”, which is a problem actually for multiple reasons. We can’t modify an existing item that is actually configured with a wrong HOSTADDRESS format, resulting to the following error : We also can’t delete an item that is with this kind of HOSTADDRESS format. It does nothing when we click on delete → Just actualizing the interface, but the host still here, and poller config doesn’t see any change. Even if we restart the poller config, it doesn’t do anything (in case it was a ghost change) We have many commands that uses the HOSTADDRESS value, which is not a valid IP (or FQDN) (for certain api calls for example). > This would require to refactor many of our commands. > We can’t deploy any new hosts that are using these commands. > And we can’t really refactor because we won’t be able to change the

I would like to see the SLA availability level for each host in my host group over a period of one year. Which metric and widget on the dashboards would allow me to find this out?Thank you in advance!

Hello, since the rotation GPG key (i suppose) the rpm-standards packages for centreon are unavailable on artifactory.https://packages.centreon.com/ui/native/rpm-standard/I see that they are possibly still on the rpm-test-standardWe need those packages to be back available as soon as possible. If this intended, please tell me what is the expected operation to access those packages again

Hi all,My version of Centreon is 25.10Any idea why its asking for my username/password when I try and use my copied autologin url:https://192.168.20.29/centreon/home/dashboards/library/3?autologin=1&useralias=autologin&token=cQSPFRHWEe When I use this link it works fine without asking for username/password:https://192.168.20.29/centreon?autologin=1&useralias=autologin&token=cQSPFRHWEebut then if doesn’t take me to my dashboard.Interesting if I use my first link after using this link it works fine.thanks for help.Steve.

Hello,Is there a plugin HP MSA 2000 for a poller under DEBIAN ?https://docs.centreon.com/fr/pp/integrations/plugin-packs/procedures/hardware-storage-hp-msa2000-snmp/Thanks,

Hi,I would like to purchase the IT-Edition to be able to install plugins on my centreon. I recently updated to 25.10.I find the web page about licences a bit confusing. It says the free version can be used with up to 100 hosts, and the “IT Edition” is showed as “2.2€/host, 275€ for 125 hosts”.I already use centreon with the Free edition marked as “Up to 100 Hosts” but I already have  300+ hosts that are monitored. Is the “Up to 100 Hosts” limit based on the number of SUPERVIZED hosts or on the number of Centreon poolers? Does that mean that if I only want one Centreon machine (1 pooler) but with 300 supervized machines I can have a licence for 2.2€ per month? Thanks, 

Is there any configuration to graph ping host performance data .All my are populated with perfdatas ,But i see no graph …Any idea ?

​Hello,I think you must separate the client support and server support in the Centreon ecosystem.As we don’t need the support for installing the server part of Centreon early on new distribution releasesWe need it as soon as possible for monitoring hosts. Because that is the goal on a monitoring solution.As today , 3 months after Debian 13 release and 6 month after the RedHat 10 release, we can’t monitor efficiently theses hosts.How can I say to customers that they will not be monitored because Centreon is unable to support majors OS at their release and event months after ?CMA is not ready for production (too young, features are missing, new tcp ports, new security mechanism, changing enterprise way to do are long path.), so we can't deploy it yet.You must ensure a period of transition when changing this type of components, by still providing the previous agents and the new one. Both on current OS releases.So we need to be able to do it with the current tools like NRPE4https://docs.ce

Hi, I’ve used an older version Centreon 2.4.1 (yeah really old! lol) and I never had this issue, but now on 25.10 I have the issue where when I delete a host it then deletes all the services linked to the host even the ones that are used by other hosts.  Obviously this is massive issue and will lead to my staff accidentality deleting services when they delete the hosts.  I don’t remember this being an issue in the older versions of Centreon.Is there a workaround for this?  I don’t really want to use service groups / host groups as I don’t want hundreds of different host groups based on my services, I need it to be a bit more flexible.Is there a way to prevents the deletion of the hosts and only allows disabling? or a way to stop centreon deleting the services when the hosts are deleted.thanks in advance.steve.

Hi all,Just another questions, I get this results when I try and install the monitoring agent pack on my alma 9 central server:dnf install centreon-pack-operatingsystems-linux-centreon-monitoring-agentNo match for argument: centreon-pack-operatingsystems-linux-centreon-monitoring-agentError: Unable to find a match: centreon-pack-operatingsystems-linux-centreon-monitoring-agent Any ideas where I am going wrong?Its the Open Sourced edition version 25.10thanksSteve.

Hello,We started to use the REST APIv2, but we noticed that there is no delete operations for the commands term point (/configuration/commands)Is there a reason for that ? or it’s planned to be implemented ?
