At present, Centreon is not yet widely recognized across Canada, particularly in regions such as Western and Northern Canada, including Winnipeg, Saskatoon, Edmonton, and Vancouver. In my opinion, to increase visibility and drive adoption of this platform, it would be beneficial to consider establishing a headquarters or regional offices in these markets.Currently, Centreon appears to have a primary presence in Toronto, while many Canadian IT organizations already rely on well-established U.S.-based platforms such as Datadog, Splunk, and other similar solutions.To strengthen its position in the Canadian market, Centreon will likely need to invest further in local presence, strategic partnerships, and marketing efforts.

Hello Centreon Community, We’re running some tests on Gitlab, and we want to trigger alarms on Centreon once the tests fails. We didn’t find a plugin that can connect Centreon with Gitlab.Is it possible to create alarms in Centreon through API calls ? Is there another alternative to do so without API calls ?We’re using Centreon 2.8.23

Hello,When a host goes down, all its services go to the UNKNOWN state to prevent unnecessary checks and notification spam. I believe this behavior is caused by the engine setting “Disable Service Checks When Host Down” being enabled.While this setting addresses one issue, in my case it creates another.I have many services that do not need to be checked frequently. Some are being checked once a day, while others are passive services that may not receive updates for weeks.All these services go to the UNKNOWN state when their host go down and remain in that state even after the host comes back up.They will stay UNKNOWN until the next scheduled check or passive update is received which, as mentioned, could take weeks.To work around this, I have to manually force check all affected services, sometimes involving thousands of services at once. Since the GUI limits bulk forced checks to 100 services at a time, I ended up writing an API script to handle this…This behavior does not occur when th

Hello everyone, I have an issue with the IT-100 subscription. I had Centreon 25.10 on an old RHEL 9 server I decommissionned and deleted where the subscription was active and working.A few days ago I installed Debian 13 and Centreon 26.10. I requested a new token, and got a mail that the token is unchanged.I went to the UI to add the token, and when I did it said “You have successfully linked your platform”. Then the add token button became “Choose subscription” and when I click on it, it says I don’t have any valid subscription.license-manager.log says : REST call failed : no subscription foundWhat do I need to do ? Maybe the old platform is still linked ?Regards

Private Synthetic Monitoring Zones (STM Zones) are now available in Centreon Experience Monitoring, to monitor your internal applications. What it means A private STM Zone allows you to monitor your user journeys on internal domains or networks specific to your organization, using a probe deployed inside your infrastructure.Your internal applications are no longer out of reach: CRM, back-office, intranet, business portals, ERP... You can now run user journeys on them.  How it works The probe is created and launched on a machine inside your infrastructure with the Docker commands provided in Centreon Experience Monitoring. You can then analyze your internal journey just like a regular user journey.Two types of probes are available: STM probe: collects the usual performance and availability metrics used by Experience Monitoring. Recommendations probe: provides personalized recommendations to optimize your applications.  Monitor from several locations You can create several STM Zones, f

Hi everybody,My infrastructure is Central and poller is AlmaLinux 9.8 with Centreon 24.10.31.I made a lots of tests with CMA for Windows and I have a lot of questions : I tried CMA for Windows with Agent Initiated and for me there is a bug when I stop the CMA Agent to the host, because not warning and alert when agent not responding anymore. So I set freshness parameter to the service and that not working, when I set to engine, it’s working on duration (total time) and not on the last check and that my services became unknown every time that the time setting on the fresnness Parameter. that isn’t perfect for production environment.After that I tried with poller initiated the connection to the host, and there a lot of problem when CA installed to the infrastructure. but I found a solution for working this way with (need to creat a private key and generated the public certificat by the CA. did you try with CA Windows Corporate solution ?but some problems that i met, first : when the poll

Hello,we need to upgrade an existing Centreon poller from Centreon 23.10 to Centreon 24.04 in order to align it with our Central server, which is currently running Centreon 24.04.The poller is running Debian 11 (Bullseye).The repository previously used for Centreon 24.04 was:https://packages.centreon.com/apt-standard-24.04-stable/However, the Bullseye distribution is no longer available.The Bookworm distribution is still reachable:https://packages.centreon.com/apt-standard-24.04-stable/dists/bookworm/but its package indexes are currently empty.For example, the current InRelease reports:main/binary-amd64/Packages: 0 bytesmain/binary-all/Packages: 0 bytesAs a result, APT cannot retrieve any Centreon 24.04 standard packages.We have another working Centreon 24.04 server running Debian 12, which was upgraded while these packages were still available.It currently has, among others:centreon-engine   24.04.19-1+deb12u1centreon-broker   24.04.19-1+deb12u1centreon-gorgone  24.04.14-1+deb12u1cent
