HA cluster primary node doesn't cluster config or hosts with secondary node (or vice versa)

Hello everyone,We are currently trying to setup a centreon monitoring HA cluster on debian 11 and are currently trying it out in our test network. We installed 1 central server, 1 secondary and a poller/quorum deviceWe made the decision to install the HA feature described as in the official centreon documentation, unfortunately we ran in some trouble. The PCS cluster and all its resources look like they work correctly but the configuration of the primary node doesn’t get failed over, this means that in practice we have 2 different centreon installations instead of the clustered HA configuration that we want aka split brain.The secondary node does become the primary node but it doesn’t have any of the config or hosts that we added on the primary.We would really appreciate if any of guys could point us to the right direction.I’ll post some examples of what I mean below.Output of crm_mon -fr on node-a while node-a is also the master serverI added a test host on node-aI failed the cluster

Centreon DSM execute two checks at the same time into the same slot

Hello, I am using Centreon DSM and I noticed that sometimes DSM execute two check command to write two different traps (alert) into the same slot at the same time, therefore the second check overwrite the status of the first one. Any ideas why I am having this behavior ?Thank you.Best regards.

Random operation of hosts

Good morningI have just installed and configured a collector to add it to centreon central and I encounter some problem Centreon version 21.10:-When I put the hosts on the collector it works half the time and when it doesn't work I get a message "(No output returned from plugin)" The equipment is correctly configured to accept the collector. When I put the host back on the central I have no problem.

Compte AD bloqué après une seule tentative de connexion / AD account locked after one try

=============================================================================================== ENGLISH (FRENCH BELOW) ===========================================================================================Hello,I expose my problem here hoping to find some help...I noticed a rather strange behavior on my Centreon, I connect via LDAP.If I make a single login/password mistake, my AD account is instantly locked.On the AD side, the locking policy is 3 attempts and the problem is only encountered with Centreon.Real example:Here we can see 3 attempts with failure, except that I tried to connect only once.As if Centreon retries several times by itself? ==================================================================================================== FRENCH ======================================================================================================Bonjour,J’expose mon problème ici en espérant pouvoir trouver de l’aide…J’ai remarqué un comportement assez étrange sur mon Centreon

Why quotes aren’t shown when command is displayed in the UI?

Hi,When the command is displayed in the service detail panel, simple quotes (and maybe some other characters) aren’t displayed. They’re present in the copied text though.If a user selects the command to copy it (instead of using the copy button), then pasts it in a poller’s terminal to execute the command manually, then it may not work.I don’t get the point here. Is it a bug or a bad UI design choice?

AlmaLinux compatibility for next Centreon versions

Hello,When we search for supported OS for the 22.10 release, AlmaLinux 8 is listed, but there is a remark about the next release (23.04):We do not recommend installing Centreon on CentOS 7 or RHEL/Oracle Linux 7. Indeed, as of Centreon 23.04, only EL 8/9 and Debian 11 will be supported. What about AlmaLinux 8? Will it be supported? We are planning to migrate all of our customers' Pollers to this OS so we wanted to make sure it is a good OS to migrate to :-)https://docs.centreon.com/docs/installation/compatibility/ Thank you!

Protection of sensible macro values

Hi,I have a service with the HOSTSNMPEXTRAOPTIONS protected.In the service details I get this : I suspect this is a bug. We should be able to see a part of the executed command.The command (which is a command definition provided in a plugin pack) is defined as :  $CENTREONPLUGINS$/centreon_generic_snmp.pl --plugin=apps::protocols::snmp::plugin --mode=numeric-value --hostname=$HOSTADDRESS$ --snmp-community='$_HOSTSNMPCOMMUNITY$' --snmp-version=$_HOSTSNMPVERSION$ $_HOSTSNMPEXTRAOPTIONS$ --oid='$_SERVICEOID$' --format='$_SERVICEFORMAT$' --warning=$_SERVICEWARNING$ --critical=$_SERVICECRITICAL$ $_SERVICEEXTRAOPTIONS$This is a problem which is present since a lot of time (at least from 18.04). It would be nice to see it fixed.In addition, I think that having macros for the options needed for SNMPv3 would be a good idea. Put all the options in HOSTEXTRAOPTIONS or SERVICEEXTRAOPTIONS is not ideal. I’d like to be able to protect the SNMPv3 authpassphrase and privpassphrase without protecting t

Issue with setting up a poller 22.04

Hi,I’m running a centreon server with 2 remote pollers,each poller is installed on a different Network and we have a FW between them.I was able to configure one of the pollers without any issue but the second one doesn’t come online.I can see the master server is trying to communicate on port 5556 with the poller but its not able to communicate with the poller (I tried to telnet the port without any problem from the master server).I also checked the /etc/centreon-engine and /centreon-broker and they are missing all the needed poller configuration files.I also noticed the poller doesnt listen on port 5669 even when centengine process is running, I also verified it loaded the broker module.It looks like the master server is unable to copy the configuration files to the poller.is there a way to troubleshoot that?

Centreon DSM server configuration file (centreon_dsmd.pm)

 Hello,we want to use Centreon DSM on our environment and for now we are testing it, however, for the first time it seems working well until we acknowledged a service to free a slot, the slots has been freed but when we generate another trap, the alert doesn’t show up on the interface, and when we checked the database we found the trap already stored on mod_dsm_cache table which mean the dsm_client did his job. I have to mention that another entry where found on mod_dsm_lock.so after some investigation, I tried to change clean_locks_time and clean_locks_keep_stored option in centreon_dsmd.pm file from 3600 seconds to 5 seconds and it’s working. (actually when I made the change in the configuation file, it didn’t work so I edited the script file directly and it worked). My questions are:1- What is the purpose of these two options  ( clean_locks_time and clean_locks_keep_stored) ? and what are the effects of my changes on the monitoring ?2- How mod_dsm_cache  and mod_dsm_lock works ?
