Centreon Broker won't start (segfault on cbwd daemon)

Hi,I’m currently running a Centreon 23.04.7 on Debian 11.After a server reboot, centreon-broker daemon won’t start. This occurs “maybe” after a disk full because of /var/lib/centreon/metrics taking full space of my HDD, and i’ve done a deletion of all files in this directory.Looking at my service logs, the service starts in loop :● cbd.service - Centreon Broker watchdog Loaded: loaded (/lib/systemd/system/cbd.service; enabled; vendor preset: enabled) Active: active (running) since Sat 2023-09-23 15:56:18 CEST; 9min ago Main PID: 1131 (cbwd) Tasks: 3 (limit: 9492) Memory: 1.6M CPU: 1.052s CGroup: /system.slice/cbd.service └─1131 /usr/sbin/cbwd /etc/centreon-broker/watchdog.jsonsept. 23 16:05:10 centreon cbwd[1131]: [2023-09-23T16:05:10.263+02:00] [cbwd] [error] cbd instance with PID 6824 has stopped, attempt to restart itIn /var/log/messages, i’ve got this beautiful segfault error :centreon kernel: [ 338.996927] cbwd[4904]: segfault at 0 ip 000

Plugin Centreon Cisco standard

Bonjour to all,I was testing this plugin lately and stumble upon what seems to be, if not a problem with the plugin itself, more a problem with its documentation. which states :Mode:     Check interfaces.    --add-global             Check global port statistics (By default if no --add-* option is             set).    --add-status             Check interface status.According to the test I just made that’s the --add-status which is the default in case of none specified, not the --add-global$ /usr/lib/centreon/plugins//centreon_cisco_standard_snmp.pl --plugin=network::cisco::standard::snmp::plugin --mode=interfaces --hostname=10.*** --snmp-version='2c' --snmp-community='***'  --interface='^Ethernet1/24$' --nameOK: Interface 'Ethernet1/24' Status : up (admin: up) $ /usr/lib/centreon/plugins//centreon_cisco_standard_snmp.pl --plugin=network::cisco::standard::snmp::plugin --mode=interfaces --hostname=10.*** --snmp-version='2c' --snmp-community='***'  --interface='^Ethernet1/24$' --name --add

Events missing in Stream Connector

Hi, We use Stream Connector to send all events to Logstash (with `logstash-events-apiv2.lua`) to automaticaly create tickets in Jira.Since few days, don’t know really how many, the Stream Connector don’t send all events to Logstash. Some events are missing.I duplicate an existing service that frequently fall on Critical. The new one is send to Logstash but the old one still don’t. Someone have already experienced this and know how to resolve my issue?

Question regarding on-prem server partitioning

Hi there !I’m about to install Centreon on a Debian virtual machine, and stumbled upon something in the documentation that left me wondering.The prerequisites chapter of the documentation states that the server must use LVM. Ok, no problem here.But it also indicates how my server should be partitioned, without saying what would happen if I don’t follow these indications.So, I’d like to know : what am I risking by using LVM with a different set of logical volumes ? For example… fewer logical volumes (that would suit me 🤔)Thanks.

New “Resources Status” page

Hi,I’d like to share the feeling I have about the new “Resource Status” page with the community.In my opinion, the old pages should have never been considered deprecated and not used by default. This is rather this new page that should have been considered a feature preview and made optional.These are some of the reasons I see:1) The new page needs a screen with a big definition or else the detailed status (ie: the output of the plugin) is not even visible without removing some columns or zooming out. To put it another way: the layout is far less compact.2) It’s impossible to filter on the plugin output (ie: the “Information” column in the new page). This is handy when you have a specific issue on some checks, and in some other cases.3) The popup on mouseover just doesn’t exist. This is handy to quickly see host or service information, without the need to load a new page.I’ve been told that the deprecated pages were still maintained for bugfix while there is still missing features in t

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?
