Hi the community,I’m looking for a way to disable notification globally on my Centreon.In “host” or “service” config, there is a value “default” for the notification parameter, but I can’t figure out where is the default value for notification.Do you have any idea ?David

Hi, I found on the Centreon 19.04 documentation that we could use the plugins pack offline by installing with yum the whole catalog yum install centreon-pack* and then we should have plugins list available on our plugins pack section. But even after I installed them I still have “no plugin found” as result on the plugins pack section.On the license-manager.log I can see the error “[RestNotFoundException] https://api.imp.centreon.com/api/license-manager/instance/subscription : Page not found” so maybe is there a way to specify that we want to use offline mode instead ? Or am I missing a step ?Thanks a lot for your help

hi,I’m trying to configure centreon to carry out SSO using CAS with LemonLDAP. the integration is working fine when the account is present. however I have enabled auto import but if the user is not present then so login end up on an empty page with errors like https://sup.zeop.biz/centreon/api/beta/administration/parameters {"code":500,"message":"[Centreon\\Domain\\Security\\Session::setUserId]: The value cannot be null"}. the documentation hints that with openconnect auto ldap import is working but is there a way to make it work using CAS or SAML ?cheersErik

Hi guys, first of all sorry for my bad english.I'll try to be as clear as possible.in our infrastructure we have a centreon version 22.10.7 (AlmaLinux 8) and we are having this problem:if a non-admin user with an associated ACL goes on "Status Details" -> "service" and then click on one of the services, the page goes into this error: If that same user goes instead to "Resources Status" and then looks for the same specific service, there are no problems.This happens on all services hosts the user is allowed to.No problem with “admin” users.I don't know if we are doing something wrong with acl but it also happened on another server updated to 22.10.x.this did not happen with the 21.x versions.Any help is appreciate.Tnks

Centreon installed properly (debian11) without errorAll services running (cbd, apache2, mariadb, gorgoned, centengine...)When I try to create the first host, “Check Command” box is empty (no plugin listedinside).When (i) is clicked, we get a popup : “ sh: 1: /usr/lib/nagios/plugins: Permission denied “(all files under /usr/lib/nagios/plugins directory are root:root)Ever seen this issue ?Thanks

CentOS Linux release 7.9.2009 (Core)Centreon v 22.10.7 Hi the community,I’m currently experiencing a strange issue.1 host has been deleted via the GUI and I’m still receiving notifications.***** Centreon notification *****Type:    PROBLEMHost:    **MY HOST**Address: **IP WAN**State:   DOWNSince:   5d 2h 51m 52sInfo:    CRITICAL - **IP WAN**: rta nan, lost 100%  I can not see this host or this service via the GUI (even if I change the URL to force the host id) .I looked at the database, was able to found those ghost entries in centreon_storage / table hosts, services and resources.Even if I set enabled, notify to 0, clear next_check  or delete the record

Hello guys, Im using Centreon version 22.10.7. I want to use bash script as a command for sending notifications. The script basically takes notification info as argument, creates HTML and then sends this document using muttt via postfix. As per my understanding notification commands are issued by the centreon-engine user. So I made sure the script is located in directory which is accesible by this user (/usr/lib/centreon/plugins/) and gave  chmod +x and 777 permission to the script itself. When I log in to ssh using centreon-engine user and use the command it works perfectly fine. The setup in the web GUI look like this: Is there something Im missing? Been trying to solve it the whole day.. please help Thanks in advance for any kind of lead :-)

Hello,We have three different Windows domains. We have a user to monitor infraestructure, let’s say ‘Monitor’, defined in all three domains. Password for this user is different in every domain.According to this article (https://docs.centreon.com/pp/integrations/plugin-packs/getting-started/how-to-guides/windows-winrm-wsman-tutorial/#configure-kerberos-on-the-centreon-server), when configuring pollers you create a file called Monitor@keytab ‘to allow reconnection without a password for the reinitialization part’.However, If I repeat the process for every domain, I will rewrite the same file three times. How do I have to do when configuring three different domains with the same user? Do I have to use different users? Can I follow the

Hi,We have here Centreon 22.04.We use the clapi binary on our Central Server to manipulate Centreon objects: particulary to import /build hosts, hosttempletes, servicestemplates ...etcThe binary is provided by the package "centreon-web-22.04.7-5.el7.centos.noarch"EX:/usr/share/centreon/bin/centreon -u admin -p XXX -o HG -a show/usr/share/centreon/bin/centreon -u admin -p XXX -i my_file.txt  # THIS WILL IMPORT THE CONTENT OF THE FILE Now we need to run this but from another linux server (Not on the Central), be I wonder how it is possible : ? Install the binary but how to specify where is the Centreon environment (database) to modify.In other words : we need to run imports/creation of centreon objects remotely.Has anyone already done this before ?I know ‘centctl’ : but is from community and not supported by Centreon …Thanks a lot !
