Upgrade 21.10.3 : affichage toujours en 21.10.2

Salut,Je viens de faire l’upgrade de la 21.10.2 vers 21.10.3 ce matin. Centreon m’affiche toujours que je suis en 21.10.2, est-ce un bug ? ou c’est mon update qui a fail ?Lors du processus d’update au lieu de mettre que je migrais vers la 21.10.3, le setup à laissé un vide.Comme un débile j’ai reboot le serveur après la MaJ des pacquets et fait le processus de migration via l’interface web après ce reboot… Est-ce cela qui a posé soucis ?Le processus m’a juste indiqué qu'il vidait le cache et c’est tous !Si ça vient de moi comment relancer l’upgrade ? (j’utilise l’ISO Centreon avec Centos 7)

Adding a poller to a Server - API Questions

Hi,Our company recently bought another one, I want to monitor them as I do for us.The other copany is linked via an ipsec tunnel, their bandwith is currenly low (2-5Mb/s)Instead of having two servers, I did install a poller and link it to our current server.Is the bandwith enough for that ?--The poller is currently installed (v21.10.2 as well), i’m trying to register it.https://docs.centreon.com/current/fr/installation/installation-of-a-poller/using-centreon-iso.htmlInstead of using the admin account, I created an api account, that has the right to use the api (for safety reasons)/usr/share/centreon/bin/registerServerTopology.sh -u USER -t poller -h SERVERIP -n POLLERNAME When I try to log in via http it tells me ‘invalid’ credentials, i’m copying the password directly so it can’t be wrong.So here is my question, the api account has to exist on the poller or on the server ?- ERROR - http://SERVERIP:80: {"code":401,"message":"Invalid credentials"} Also at first i wanted to use https for

BackupAge on sql server

Hello watchers, I have a little issue with backupage monitoring on SQL server.I explain:We have multiple MSSQL servers in our organization.We configured MSSQL plugin to monitor them.We do a full backup every friday and an incremental every day (Tlogs every hour).In Centreon, it seems it just take the full backup value to have the backupage value. Is it normal? How can I do the value of backupage take in count the incrementals? Regards, Laurent

Linux NRPE3 - File Size permission denied

Hello everybody !A few weeks ago, we installed Centreon 21.04 and we started to use it in production.Our Oracle DBA want to check the size of a file in an Oracle Enterprise Server 7 Server. For that need, we installed the linux NRPE3 plugin pack (https://docs.centreon.com/current/en/integrations/plugin-packs/procedures/operatingsystems-linux-nrpe3.html) and use the service template “OS-Linux-File-Size-Generic-NRPE3-custom”. If we check the size of the file our dba want to, the state become UNKNOWN “ Command error: du: cannot access 'filepath': Permission denied“ (Filepath = the exact path of the file I don’t want to share here ^^).We have the same result for any files or directories in the monitored server except one, “/etc/nrpe/centreon-nrpe3.cfg”. When we check this file, we have the size of this file as result so the check works for me.On the monitored host, we tried to change the “nrpe_user” and “nrpe_group” options to “root” instead of “centreon-engine” in the file centreon-nrpe3.
