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.

use of templates in the configuration of a host

Hello,When you want to use the templates in the configuration of a host, you have to click on the "Create Services link et to the template too" button.I found an article from 2015 in French from a blog: https://blog.zwindler.fr/2015/04/18/centreon-hostgroups-modeles-dhotes-la-reponse-de-centreon-a-mon- item/Is the solution given at the time still the same? I am using Centreon 20.04.Thanks in advance

Unattended installation of a Centreon Remote

Is is possible to use unattended.sh to install a remote server?https://github.com/centreon/centreon/blob/develop/unattended.shReading both documentation and code, I see one difference:During web installation, it is not necessary to install Autodiscovery module:https://docs.centreon.com/current/en/installation/installation-of-a-remote-server/using-packages.html#web-installationIn the code, I see ‘process_step8.php’ with something about Autodiscovery:https://github.com/centreon/centreon/blob/a609307ce94937b06157f479b66a14ae5ec465bf/unattended.sh#L647There are other difference or attention point?

Using AD groups for Permissions to Centreon

This might be a silly question, but we are trying to get permissions working with AD groups. We’ve got everything setup and if we add by user account everything works fine with the Access Groups, Resources, etc.. However if we try and add a AD group, no one can login. I’ve tried many different combinations and locations where to add this group but nothing seems to work. I assume based on the Users, and the filter string that groups do not work, is that correct? Or is it something I am just missing on how to assign permissions to AD groups?Thanks in advance, Matt

Problème "La connexion a été réinitialisée" sur l'interface web Centreon

Bonjour,Je suis en train de tester des plugin packs sur mon serveur de test, jusqu’à hier tout marche bien.Mais depuis ce matin j’ai un problème étrange en modifiant un hôte ou un service. En fait si je clique sur “sauvegarder” après avoir modifié la conf d’un service ou d’un hôte, j’aurai un écran comme ça :Par contre je peux modifier les conf de “Notification”, “Utilisateurs”,etc. Ce n’est que la conf dans la partie “Service” et “Hôte” qui me pose problème.Est-ce qu’il s’agit d’un problème niveau BDD?Merci d’avance.

Installation phpmyadmin

Bonjour,Ma question n’est pas directement liée à centreon mais je pense pourra aider les non expert de Centos.J’utilise Centreon 21.10 (ISO 21.04 de base).Il y a quelques mois j’avais réussi à installer phpmyadmin non sans mal …En utilisant les packages rh-php73 etc… j’ai supprimé php 7.3 depuis, j’avais plusieurs versions de php en fait. J’avais du mettre une conf php ici : /opt/rh/httpd24/root/etc/httpd/conf.d sinon phpmyadmin ne marchait pas. J’aimerais éviter d’avoir de nouveau plusieurs versions de php.Tout semble fonctionner normalement, je suis en php 8, sauf que phpmyadmin n’interprète plus le php (page blanche, juste le html)Comment faire pour que phpmyadmin trouve php correctement ?Merci

Apache security vulnerabilities CVE-2021-44790 & CVE-2021-44224 impact on Centreon's product

SummaryA zero-day exploit for a vulnerabilities in Apache versions less than 2.4.52 (CVE-2021-44790 & CVE-2021-44224) was publicly released on December 23rd, 2021. A detailed description of the vulnerabilities can be found here:CVE-2021-44790 CVE-2021-44224Centreon conducted an initial assessment across the codebase to determine the impact of this vulnerability. Impact CVE-2021-44790 A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. Centreon does not use mod_lua for its default Apache configuration. If you have not added a third-party configuration, no impact is to be reported. CVE-2021-44224 A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configuratio
