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.
