Changing configured database password

Hello !Firstly I’d like to thank all readers for your time and consideration. Now here’s my issue. When setting up centreon and mariadb along with it, I used a password containing ‘&’ and this would not have been a problem if I was not using NagVis as a plugin for centreon. The thing is that they use the same database and the same database user as well but NagVis config file raises errors when using characters such as ‘&’ or ‘²’ in the dbpassword variable.(I already tried to escape using ‘&’ by encoding it in UTF8 or ‘&’ but it doesn’t work) To fix this issue, I looked for a way to reconfigure database configuration in centreon but didn’t find anything, so I manually changed the hardcoded password in the multiple conf files which worked for a bit. But now, when I restart centreon-broker from the web interface, it replaces the password I replaced by the one with ‘&’.

Object not found in Centreon API Centreon CLAPI

Hello everyone,Being new to Centreon, i just discovered clapi and tried to type a command line to do an action on a particular host but i get everytime such an error “Object ‘MyHost” not found in Centreon API”. So, i went to centreon documentation (https://docs.centreon.com/docs/api/rest-api-v1/) and saw that it was an error perhaps from an authentification matter. My errors are the 401 and 404.I can’t find a solution for the moment. I need help. Thank you :)

Edit locked commands

Hello,I have the four checks related to OS-Linux-SNMP which are bugged.Indeed, these are configured as follows:$CENTREONPLUGINS$/centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=cpu --hostname=$HOSTADDRESS$ --snmp-version='So, I wanted to modify them.To do this, I go to /etc/centreon-engine/commands.cfg and I make the necessary changes to the commands having the problem.However, when I reload my pollers, the commands return to their initial state, before modification.How to make so that the modifications are integrated and remain so?Thanks in advance

SNMP Trap configuration (Advanced matching rules)

Hello,I want to configure traps on my Centreon server to receive alarms from a router, and now I am trying to find the best configuration to do it, for that I want to know if it’s possible to add a variable (macro) to an advanced matching rule, I tried to add $1 and $p1 but it didnt work it’s print the variable but not it’s content. (see image below)my idea is rather than adding a matching rule for every possible interface, I want to do it with one rule for similar interface names for example for GigabitEthernet0/1 and GigabitEthernet0/2 I want to add one matching rule like “GigabitEthernet0/$1” and the macro $1 here contain the interface index (1 or 2).. is there a way to print a variable in the matching rule ?  Thank you for helpRegards

Error while reading on socket

Hello !I recently installed Centreon 22.10 using the OVA image given.I then updated it to 23.04 using the documentation. (Upgrade from Centreon 22.10 | Centreon Documentation)Then, using the web API import/export, populated it with centreon 2.6 hosts, services etc..In the broker configuration I changed the conf file from “central-module.xml” to “poller-module.json” and the central was up. I then changed the conf files of central-broker-master to “central-broker.json” and central-rrd-master to “central-rrd.json”. Following these changes the central went down as such.I followed → My poller is down | Community (centreon.com)But did not find an answer.I have found errors in /var/log/centreon-broker/central-module-master.log : [2023-05-30T16:28:58.259+02:00] [core] [info] multiplexing: engine started[2023-05-30T16:28:58.261+02:00] [core] [info] Poller '' with id 0 connected[2023-05-30T16:29:11.051+02:00] [core] [info] bbdo stream stopped with 0 events acknowledged[2023-05-30T16:29:11.051+02

We are using a VPN, the domain cannot be resolved publicly.External URL (after reverse proxy):IDP : https://idp.external.XXXX.intra Centreon : https://supervision.external.XXXX.intraInternal URL (before reverse proxy):IDP : https://idp.internal.XXXX.intra Centreon : https://supervision.internal.XXXX.intra The problem is, when I click on “Login with openid” button after configuring OpenID Connect authentication, I get redirected to an URL like this :https://idp.external.XXXX.intra/application/o/authorize/?client_id=XXXX&response_type=code&redirect_uri=http://supervision.internal.XXXX.intra/centreon/authentication/providers/configurations/openid&state=648057e829375&scope=openidThe redirect URI is false here because Centreon is taking its own internal URL and we want that the redirect URI would
