Centreon Infra Monitoring

Hi, on https://docs.centreon.com/docs/alerts-notifications/resources-status/#cql-criteria  I can read:  You can use regular expressions. Wildcards are not supported: a search pattern starting with a * is not valid.So `.*` isn’t supported anymore? But it seems than things like `[0-9]` aren’t either. So my question is, what regex I may use there?Use of regex was one of the rare amelioration this new page has, so I’m a bit disappointed. Second question, does a stabilization in how the search works is planned or will be there some other modifications in the future? 

In the centreontrapd.log log file I have the following error which returns every minute:2024-05-07 08:09:49 - ERROR - 528 - MySQL error : cannot connect to database : Access denied for user 'centreon'@'localhost' (using password: NO) (caller: centreon::common::db:/usr/share/perl5/centreon/common/db.pm:268)2024-05-07 08:09:49 - ERROR - 528 - Cant load cache trap oids.2024-05-07 08:09:49 - ERROR - 528 - Dont skip trap. Need to solve the error.Is there a setting to modify to no longer have this error? Centreon still works.

I have install centreon  with remoteDB and one poller  based on centos8  ,it works well. but now I want to change the IP addresses of these three servers, and I would like to know which configuration files I need to modify to ensure that the monitoring system functions properly after the change.

Hello, I configured a fresh install of Centreon version 23.10.6 few months ago and I'm experiencing a strange problem with the service graphs.Some of them stop filling up after a random time but information collected are still correct, only the graph is impacted. SNMP v2c and v3 with a snmp user have been configured and tested on Windows and Linux to contact monitored servers. This happens randomly on Windows or Linux, sometimes in the same subnet (so not a firewall issue), sometimes not, and randomly on SNMP v2 or v3. On the same monitored host, not all services are impacted.When I restart the poller, graphics works for about 1 or 2 hours, then stop filling up.Does anyone have any ideas?Thank you in advance,Regards.

Is there a way to make alert notifications per user? That is, only one slack channel is notified (for example, in my case I use slack) of all alerts from hosts/services to which a given user has access.

Hi !I meet a problem when i import my exported files.Context : i exported all the services in one file.zip with the import/export centreon tools.I need to re-deploy my centreon virtual machine and re-install it.Before it, i exported 3 files : the hosts the services the commandsI redeployed/reinstalled the VM and Centreon and with my new instance, i imported the 3 files. The first problem is that when i import anything, i got the message ‘please wait… this process can take several minutes’.But after a long moment i refresh the page, export the poller configuration and reload it, and i see that i got new hosts for example.But for the services and commands, i imported it and there are a lot of missing from my exported configuration.I try to compare my previous configuration and new, and there are a lot of differences, somes commands was not imported, same for the services etc…Is someone met this problem already ?Is someone has a solution for me please ?Regards.Olivier

Hi !First topic here, feel free to help me format / edit things or give feedback ! I’m new to centreon, but i’ve seen that there are quite a few topics related / with similar issues, but yet I can’t get my head around this issue !I’m trying to install a new server with local database, following the “using package” doc https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-packages/ The final aim would be to migrate from a 20.10 on our old infra to this new serverI’ve seen another post do it, I run an Oracle Linux Server 8.9, with ARM proc# cat /etc/*release |grep NAMENAME="Oracle Linux Server"PRETTY_NAME="Oracle Linux Server 8.9"CPE_NAME="cpe:/o:oracle:linux:8:9:server"# uname -maarch64# uname -r5.15.0-203.146.5.1.el8uek.aarch64I feel like I’ve followed every step of the doc, here is what I’ve “adapted” :End of step 1 : I tried with 23.10 and 24.04 (either one would be good for me) dnf module php : I tried with remi-8.1 and remi-8.0 Once I’ve downloaded the

i want to migrate from Centreon 2.8 on centoOS7 to Centreon 23.10 on Debian 11.While the whole installation, and webinstall went well, following that documentation , as soon as i try to transfer my databases, as indicated i get the following error on the login page of my server :Error while searching for the widgets version of the Centreon platformSQLSTATE[42S02]: Base table or view not found: 1146 Table 'centreon.provider_configuration' doesn't existError while searching authentication tokensNot only that, but i can’t log back with the credentials used on the old server, neither the one i was using before dumping my databases.I checked both /etc/centreon/conf/pm and /etc/centreon/centreon.conf.php, on both servers and they were using the same credentials on both.During the webinstall i entered the corresponding credentials for the admin profile.If you also need it, i’m running both on VMWare.I actually rolled back the new server on a snapshot who’s at the correctly ( or seemingly) con

Hello The Watch,Will we have the possibility to create this kind of graphs that we can have on custom view on the new dashboards ?It is interesting for the inbound and outbound traffic for example. Thank you for your answerBest Regards,

Hello,My monitoring server is warning me about CPU Ready consumption over 5% but when I calculate this value with extracted data directly picked from my vcenter, I’m not able to find the same result.I also installed a new system which is able to graph CPU Ready and this value for a particular virtual machine doesn’t exceed 1%.What am I doing wrong with Centreon ?It seems that this value is multiplied by 10 in the plugin.Thank you for your help. 

Hi,When I change a custom made command or a service on Centreon 23.10.11 WebUI, they are ignored until I restart all Centreon services :# systemctl restart cbd centengine gorgoned centreonIf I just try to export configuration as I did on Centreon 22.10 WebUI, all modifications made are ignored. Even if : Changes made on the command are present into /etc/centreon-engine/commands.cfg and /etc/centreon-engine/services.cfg but not on the service view from the top of the web page and are not monitored as expected.
