After Connector update, some others got installed and cannot be removed

On my test Centreon v23 I was notified that some Connectors needed updating so I proceeded.Some errors popped up for the Generic SNMP connector but after waiting and pressing OK everything looked to be fine. On closer inspection I noticed several extra ones that we did not have before, nor do we require have now also been installed:I cannot remove them either - it seems to go through the motion and the green installed icon disappears, but after a refresh they all come back. No messages are displayed and none of them are used by any hosts, using the re-install button has no effect. Rebooting the RHEL8 server does not help.How can I get rid of them?

Centron mariadb high cpu 400%

My Centreon server suddenly started consuming 400% of the server's CPU. When I checked with top command    I noticed that the issue was related to MariaDB. Then, I used mysql to list the process list, and I found several processes associated with the Centreon user. Most of these queries were identical SELECT statements. What could be causing this? How can I resolve the problem?

Poller broker stats file missing

Hi,I’ve seen there are two other topics with a similar problem but as they’re quite old I make this new one.The problem is: the Engine JSON stats file (named pipe) is missing on one of our poller. A restart of the centreon-engine service fixes the issue.I checked both the broker log and the engine log and found no error, no error in /var/log/message either.I wonder if anyone already has got this issuen and if it’s a known issue. If so, how I could avoid it.Engine log levels are the following: Engine log levelsand Broker log level are: Broker log levelsPackage versions are:centreon-broker-22.10.4-1.el8.x86_64centreon-broker-cbmod-22.10.4-1.el8.x86_64centreon-broker-core-22.10.4-1.el8.x86_64centreon-broker-selinux-0.0.5-1.x86_64centreon-broker-storage-22.10.4-1.el8.x86_64centreon-clib-22.10.4-1.el8.x86_64centreon-common-22.10.11-1.el8.noarchcentreon-common-selinux-0.0.10-1.x86_64centreon-connector-22.10.4-1.el8.x86_64centreon-connector-perl-22.10.4-1.el8.x86_64centreon-connector-ssh-22.1

And I couldn’t figure out what’s happening.Do anyone have a clue ou can give me some hints on where to look at ?Thanks in advance for your help.

Master and slave on different sites

Hi, i’m struggeling with setting up a cluster for Master & slave on different sites! i’m putting an example:Master in site A (172.30.100.10)Slave in site B (10.10.50.10)i managed to configure the cluster but i don’t know how to make the VIP work? question 1: will a public IP (static) work on this scenario? for example 102.200.85.192 from a service provider?question 2: do i need a proxy or a load balancer in this case? if so, what is the recommendation?question 3: will the poller work with the VIP? it’s been weeks now seeking for help in every forum out there; but i still didn’t get a response!please help me out. thank you

Impossible to re-select the current selected saved filter in the list

Hi,When a filter is selected, it’s possible to enter a new query, thus changing the displayed results. If one wants to go back to the previous results, he can’t select the same filter in the list again. He has to select another filter, then re-select the filter he wants.The “previous” browser button (which could be a workaround to the problem described above) doesn’t work either. And this is even more annoying, a web application should always let the user use the “previous” and “next” browser buttons.

vCenter vSphere 8 compatibility with Centreon

Hello guys, has anyone here using vCenter vSphere 8 with Centreon? Our current vCenter will be upgraded to vSphere 8 soon. We want to make sure that Centreon would be able to monitor vCenter (vSphere 8), the ESXs inside it and the VM hosts residing in it. Unfortunately, we will not have test vCenter vSphere 8 to test and check the compatibility of Centreon with it. Appreciate, your feedback on this. Sincerely,Crisanto
