24.04 to 24.10 upgrade errors on Alma 8

Hello,Yesterday we tried to migrate our Centreon infrastructure from 24.04 to 24.10.Following this, we are encountering two main errors: The first, errors in the sudoers.d/centreon fileThe second, a problem with a .DEBUG file where the values are err instead of error, and this is causing errors on the machines when the configuration is exported.To resolve this, we modified the sudoers.d/centreon file by hand to apply the full executable pathsAs well as modifying the engine configuration so that the log level is not ‘Error’ but something else such as warning or critical.Can you see how to resolve this please? Because if we have to go to each machine to make these changes by hand, which are more workarounds than anything else...Thank you

Error Attach poller to central

Hello, I have set up a remote poller that I am trying to connect to my central server. Both servers are running Alma OS 8.1, with Centreon version 24.04.5 for the central server and version 24.04.6 for the poller. I followed the documentation to do this, and when I run the command:/usr/share/centreon/bin/registerServerTopology.sh -u <API_ACCOUNT> -t remote -h <IP_TARGET_NODE> -n <REMOTE_SERVER_NAME> --insecurea connection is established. However, after adding it in the Centreon GUI, the poller remains in a "not running" state, and I have no errors during the exports. file:I noticed the following error in the Gorgone log :2024-10-01 05:28:36 - ERROR - [proxy] Send message problem for '21': 2024-10-01 05:29:26 - ERROR - curl perform error: SSL peer certificate or SSH remote key was not OK2024-10-01 05:29:26 - ERROR - [autodiscovery] -class- host discovery - cannot get platform versions - http request error2024-10-01 05:29:36 - ERROR - [proxy] Send message problem for '2

task

I am currently working on a project which consists of retrieving data from the MySQL database already installed on the Centreon poller and displaying it on Grafana.I am looking for plugins or solutions to facilitate this integration. Could you advise me on the steps needed to configure Grafana so that it can access the MySQL database and display the data?If anyone has done this before or knows the necessary commands, your advice would be greatly appreciated!Thank you in advance for your help!

Retrieve host groups with Open Ticket

Hello,we have several host groups per host. We would like to export them via OpenTicket into EasyVista. We have tried parameters such as: {$host.host_group}, {$host.group}, {$service.host_group}, {$host_selected[0].host_group}, {$service_selected[0].host_group} to make them appear in the description on the EasyVista side, but none of them work. Is there a solution to retrieve the host groups of the machines? We also have the option to use lists in OpenTicket. Knowing that only one of the host groups is relevant for ticket entry, we would like to know if filters can allow displaying only the host groups related to the host of the selected service. Best regards.

Everything seems to work but the HostGroups.  I’ve only got 3 hosts  on this new poller so far but non of the hosts show up in hostgroups pulldown on the Monitoring > status details > hosts > Hostgroup pulldown the hostgroup doesn’t even show up..   Now i can add a host from another group in it and then that host shows up  but not the three that are just for that host group. if i add one of those to another group it doesn’t show in that group either. are 23.10 central server and 24.04 poller compatible ?   <al>

Connecteur Centreon Linux SNMP option --force-64bits-counters positionnée par défaut dans le modèle livré

Bonjour,Suite à la mise à jour des plugins nombreuses sondes en unknown car l’option --force-64bits-counters a été ajoutée dans le modèle du pack.    --force-64bits-counters            Use this option to monitor a server/device that has more than 2            TB of RAM, the maximum size of a signed 32 bits integer. If you            omit it you'll get the remainder of the Euclidean division of            the actual value by 2 TB. NB: it cannot work with version 1 of            SNMP protocol. 64 bits counters are supported starting version            2c. Je ne sais pas si c’est censé fonctionner partout (j’imagine puisque cela a été activé par défaut ?) mais ce n’est pas le cas chez nous, en retirant l’option c’est OK. Pourtant nous sommes bien en version 2c.Avec l’option j’ai « UNKNOWN: SNMP GET Request: Cant get a single value. » sur un check : /usr/lib/centreon/plugins//centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=memory

reverse high avaiability done by a " centreon expert "

hello,in the start of the year , an expert was mandated for our client to make his centreon clean . Right from the start , he make the high avaibility cluster on the qualification side ..He made it with mysql 1.3 instead of 1.5 ( for some reason the repository for mariadb 1.5 , install the 1.3 version). He should have stop here , the prerequisite of mysql 1.5 was not meet. but he did it anyway. He was let go before ending his work and didnt revert what he did. Today i cant upgrade , it ask me to upgrade mysql but i cant ( always the same not resolved issue with the repo ) . We try to use a save from all of the servers but the change where already in place , and we cant go on last year because we switch from centos to redhat on january. I cant revert the dnf install of the update. I tried to reverse the HA , but it dont work. How can i reverse the HA , to not be in cluster anymore like it was before , and reuse the DB that was in place before ( and with the good mysql version ) ? Thanks

View by host

Hi,The view by host is limited to 100 objects per page: Wrong number of servicesIt leads to a wrong number of services for host, as you can see in the image below: Right number of servicesThis is utterly wrong in my opinion.Moreover, I don’t understand why the the number of objects per page is limited to such a low maximum   of 100.Is the Javascript which handles the display is so CPU intensive that displaying more objects would be too much for a descent browser?!This is Centreon Web 23.10.16
