Problem plugin vmware

Hi I have had a problem with centreon updates for some time. My version is 24.10.8. The problem is in the vmware infrastructure monitoring plugin. Previously (based on the centreon_vmware.pm file) everything worked fine. After updates (from several versions within 24.10) the centreon_vmware service does not want to start. When I change the option to old in the /etc/default/centreon_vmware file and restore the centreon_vmware.pm file, everything returns to normal.Here is the configuration and logs after updates (the last one to 24.10.8), which do not work well.My instance: Centreon 24.10.8, Debian 12. $ ls -lrazem 44-rw-rw---- 1 www-data www-data 1287 2018-10-17 centreon.conf.php-rw-r----- 1 centreon centreon 390 06-24 08:25 centreontrapd.pm-rw-rw-r-- 1 centreon centreon 390 2024-05-16 centreontrapd.pm.dpkg-dist-rw-rw---- 1 centreon-gorgone centreon 626 06-24 08:24 centreon_vmware.json-rw-r--r-- 1 centreon centreon 812 03-28 09:37 centreon_vmware.pm

“No parent platform found” error when registering a Raspberry Pi poller in Centreon

Hello everyone,I’m facing an issue when trying to register a Centreon poller on a Raspberry Pi 4, connected to my Centreon server hosted on a remote VM managed by a third party.I followed the official documentation and installed the necessary packages on the Raspberry Pi. When I run the following command on the poller: bash /usr/share/centreon/bin/registerServerTopology.sh -u <API_ACCOUNT> -t poller -h <CENTREON_SERVER_IP> -n <POLLER_NAME> I consistently get the error:“error no parent platform was found for”I checked the Centreon database (platform_topology table) and the central platform is present with parent_id = NULL.The poller and the Centreon server are not on the same local network.If anyone has encountered this issue or has suggestions, I would appreciate the help!Thanks in advance.

SSO et API Rest

Je teste actuellement une intégration avec Centreon via l’API REST (en utilisant les endpoints natifs de Centreon).Je voudrais savoir s’il est possible d’utiliser cette API tout en bénéficiant du SSO (LDAP) déjà en place.Je n’ai pas accès à une plateforme de test avec le SSO activé, mais chez l’utilisateur final, l’authentification SSO via LDAP fonctionne sur l’interface web de Centreon.Ma question est donc la suivante :Est-il possible d’utiliser le SSO (basé sur LDAP) pour récupérer le token nécessaire aux appels API ?Et si oui, y a-t-il une documentation précisant les en-têtes ou paramètres spécifiques à fournir (par exemple en complément du UseDefaultCredentials = true dans le handler) ?Merci d’avance pour vos retours !

Downtime and Business Activity

We have a BA called ba-L0, with two indicators, kpi01 and kpi02.We configure a downtime on ba-L0.An alert is created on kpi01. Is a ticket created on kpi01, or is kpi01 inherits from the downtime configured on ba-L0 ?

centreon_storage folder full

I was trying to run updates on my Centreon VM this morning and it wasn’t able to download the updates.  Check the disk size and I am seeing my dev/sda is full.  Digging in further I found that the /var/lib/mysql/centreon_storage folder is using the vast majority of my disk space.  After some googling I did find the retention settings and I change all of those values, but I assume there is a job that I need to run in order for it to go through and gracefully purge those older files?  I found this referenced sudo -u centreon /opt/rh/rh-php72/root/usr/bin/php /usr/share/centreon/cron/centstorage_purge.php, but it did not work on my system.  This is the OVA for Centreon that I am running on and I am currently on version 24.04.12.  Any help would be appreciated on this.

Open Tickets module usage with Community Edition – UI access to Notifications > Rules?

Hello everyone,I would like to get an official clarification from the Centreon Community about the use of the Open Tickets module in the Community Edition.Context: We are using Centreon Community Edition 24.x, with the Open Tickets module installed from the community repository (centreon-open-tickets). The module appears as installed and enabled in Administration > Extensions > Modules. However, the Monitoring Connector Manager shows “License required”. We have double-checked our ACL configuration: the user is an Admin and all permissions are granted. In Notifications > Rules, the page is empty and I cannot add any rules. My question is:Is it possible to use the Open Tickets module with the full graphical interface (especially Notifications > Rules) in the Community Edition without an IT Edition license?Or is it confirmed that in the Community Edition, only the method using a Notification Command or Event Handler is supported, without the connector management UI?Any

HTTP Collection : parse headers values

Hi, Here’s the matter : to get metrics from an API one has first to request the “login” endpoint, providing user and password, to get back an authentication token (with a limite time validity). BUT this token is provided in the header “Authorization”, not in the json body of the response, and I didn’t manage to get it.Is there a way to extract values of the header ?Thx.

REST API v2 & curl

Hello,is anyone has successfully queried the REST API v2 using curl and a JSON payload with a GET request? I’m trying to get a list of hosts with a specific host template. I’m not sure it’s possible as host template doens’t seem to be a usable criteria for configuration/hosts endpoint. Moreover, when I search for a specific host, the response is I must specify the address and the monitoring_server_id which differs from the documentation as I should search only by specifiying the name of the host (https://docs-api.centreon.com/api/centreon-web/24.04/#tag/Host/paths/~1configuration~1hosts/get) My curl request: curl -H “Content-Type: application/json” -H “X-AUTH-TOKEN: `cat token.txt`” “https://URL/centreon/api/latest/configuration/hosts?search” -d ‘{“name”:”hostname”}’response : {"code":400,"message":"[address] The property address is required\n[monitoring_server_id] The property monitoring_server_id is required\n"}and if I send the address & monitoring_server_id :{"code":409,"messag

How to export "Services by host group" items?

Dear Community!I have been using Centreon for a while and we have been working on migrating our Centreon infrastructure to a new environment.It is important to note that, we are using a lot of “Services by host group” type of configurations.So while preparing for this migration activity, I tried to export the whole configuration (with checking all type of objects in the Export menu). When I checked the content of the export file, I did not find any services which are configured as “Services by host group”. I’m unable to create an export, which contains also the configuration also for services, which are assigned to host groups. Has anybody experienced the same with Centreon Community edition version 24.10.8 ? Thank You very much in advance for the support!

Ghost Host still visible in Resource Status after deletion

 Hi everyone,I’m facing a strange issue on my Centreon platform.One of our clients had a dedicated poller, but they left our infrastructure and cut the connection to the Central server.I believe the administrators moved the hosts to another poller and then deleted the old poller after a configuration reload.However, one host still appears in the Resource Status view, even though it no longer exists in the Hosts configuration.Interestingly, only the services appear with a green "OK" status, while the host itself is shown as Pending (blue dot), even though it shouldn’t exist anymore.I’ve already tried restarting cbd and gorgoned, but the ghost entry is still there.Has anyone experienced something similar?Any idea how to clean this up?Thanks in advance!
