Help understanding host templates

Hi, new user here. We have deployed a centreon server only a couple of days ago and I’m trying to figure out if it covers all our needs.In particular I was tinkering with templates but seems that doesn’t work as I was expecting. I’ve created a host template with all the basic settings we need: notifications, services templates, scheduling…Now when I try to create a new host and assing this template to it, new host is inheriting only services and icon, no other fields are copied from the template.Is that supposed to work like this or I’m missing something? Thanks in advance for your attentionAlessio

Collecteur pas en cours d'exécution | 24.10

Bonjour, J’ai récemment installé Centreon sur une debian 12. L’installation s’est faite “correctement” avec la commande : curl -L -s https://download.centreon.com/24.10/unattended.sh | bashCependant je rencontre un problème, mon collecteur “Central” ne veut pas passer dans l’état “En cours d’exécution”. J’ai suivis les docs d’installation officielles de Centreon, les différents forum, etc… Mais rien n’a fonctionné. Même au niveau de ma debian, je n’ai touché à aucun fichier de conf.  Si quelqu’un à une solution, je suis preneur !

HTTP collection - aide sur les clés et fonctions utilisables

Bonjour, Depuis la présentation des collections HTTP au dernier Centreon Summit, je cherche à réaliser une supervision de l’espace disque utilisé sur un Radware Alteon par son API.Existe-t-il une documentation exhaustive des différentes clés (paramètres) et fonctions qu’on peut utiliser dans les collections en général (HTTP, SNMP et SQL) ?J’ai vu par exemple qu’il faut utiliser le paramètre “insecure=1” pour ne pas vérifier le certificat. J’imagine que ce paramètre correspond à l’option `--insecure` du mode “response” (`--mode=response`) ? Est-ce que si je déclare un paramètre “proxyurl=http://IP_PROXY:PORT_PROXY” comme je le fais avec le mode=response (`--proxyurl=’http://IP_PROXY:PORT_PROXY’`), cela fonctionnerai ?De même pour les différentes fonctions utilisables. J’en relève au moins deux : count et assign. En existe-t-il d’autre ?

centreon_linux_snmp.pl dont show exact disk free space

Hello everyone, I recently viewed that the template check “OS-Linux-Disk-Global-SNMP-custom” has a problem and I don’t know how to resolve it. The server shows the free disk storage but differs from the centreon check and the server (df command). I’m aware that the real number is what is shown in the server site, but why is centreon showing another numbers?ServerIn my server i can see the /data disk usage:$ df -h /data/dev/mapper/01--vg-data 4,4T 3,8T 476G 89% /data$ df -H /data/dev/mapper/01--vg-data 4,9T 4,1T 511G 89% /data$ df /data/dev/mapper/01--vg-data 4695587440 3996106512 498103636 89% /data Centreonbut when I use the check i see this in my /data:  I also used the same script as the service and encounters the same problem: $ /usr/lib/centreon/plugins//centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=storage --hostname=$server --snmp-version='2c' --snmp-community='public' --storage='\/data|\/srv$|\/tmp$|\/var$|\/boot$|\/$' --name --regexp --displ

Log Retention

Hello, using the Log Retention with a value 365 or even 31 the Cronjob /usr/share/centreon/cron/centstorage_purge.php doesn’t clean (all) old comments.I’ve got comments from 2017.  Responsible SQL Query to cleanup:DELETE FROM comments WHERE (deletion_time is not null and deletion_time ' . '< __RETENTION__) OR (expire_time < __RETENTION__ AND expire_time <> 0)Value for __RETENTION__ is the value from the config, in my case 365. The table field expire_time is always 0, so the second part of the query is never matching.The field deletion_time is on many entrys NULL (currently 100174 entrys) and on 3287090 entrys not null.  I’m not sure about the fields deletion_time and expire_time what are they for. But comments from 2017 shouldn’t be there in Year 2025 with retention period of 365 days.  Manually checking the filter:SELECT * FROM centreon_storage.comments WHERE (deletion_time is not null and deletion_time < 1708297200 ) OR (expire_time < 1708297200 AND expi

Centreon Poller "Is Running: NO"

​Hello, after multiple struggles i have no idea what i did wrong/So i’m using Alma 9, Centreon 24.10, Mariadb 10.11 on Hyper-V.Selinux is disabled, the local firewal disableed too.It’s a stanalone type (so only one poller “central”) After installing Centreon following the official documentation, the central poller does not appear as running in the web UI (Configuration > Pollers):MariaDB is accessible via “centreon” userCentreon port is listening i already tried this :Configuration > Pollers > Export configuration Checked "Move generated files" and "Restart Engine"  Checking for errors in the logs on cbf, dentengine, and gorgone, see nothingSo, Why does the central poller still show "Is running: NO" even though all services are running and there are no apparent errors?What additional steps should I check to ensure the poller is correctly detected by Centreon?I’m pretty sure that my mistake is dumb but I have no idea what I did wrong.​Thank you by advance,Théo

[network::fortinet::fortigate::snmp::plugin] Mode VPN : Service Discovery

Bonjour,Nous utilisons le plugin Fortigate pour monitorer nos firewalls en SNMP, le discovery du service "Interfaces" fonctionne bien mais j'aurais voulu savoir s'il était possible de l'ajouter au mode "vpn".En effet, Fortigate fait la différence entre le check de l'interface d'un tunnel VPN (qui peut être UP) et le check du VPN en lui-même avec toutes les phases 2 (Qui peut être down).Nous avons donc besoin d'avoir les 2 checks distincts or il est très fastidieux de rajouter les services à la main avec les filtres sur les bons VPN (Il y en a des centaines par équipements en moyenne).J'ai tenté de créer les commandes des Macro et Discover pour ce mode et en modifiant le script perl (En ajoutant les sections pour les paramètres --disco-show et --disco-format) mais mes connaissances restreintes en développement PERL ne me permettent pas de le faire fonctionner.Y a t'il un moyen d'automatiser la création de ces services ?Merci,
