Bonjour à tousJe rencontre une erreur etrange pedant le deploiment de centreon MBI.‘Bad Gateway’ au niveau de la création du schema du Datawarehouse.Quelqun a des pistes de solutions.Dans l’attente de votre retour .

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

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?

Hello Everyone,  We are monitoring our Cisco 8500L via snmp and the command net-cisco-standard-snmp-traffic-name for the internet connection. It’s almost working fine, except that some time (probably around 3 to 4 time), we have a value way too high registered (around 4Tb :D). The biggest concerns is that it modify the scale of the graph, which is unreadable when one of those value are registered. Is this possible to ignore a value within a graph setting ? Or any “trick” that could do the job on this kind of matter ? Best regards,

Hello,  Since the update 23.04.6, I no longer have any history on the events of my probes. I have this error message : Symfony\Component\HttpFoundation\Response::__construct(): Argument #2 ($status) must be of type int, string given, called in /usr/share/centreon/src/EventSubscriber/CentreonEventSubscriber.php on line 428 Has anyone encountered this problem before? Regards, Florian

Hello,  I set retention time to 20 days, but all of my database are growing fast.  After some researches, i found a cron task which is executed all nights. When i look into the logs, i saw this error :  PHP Warning:  file_put_contents(/var/log/centreon/sql-error.log): Failed to open stream: Permission denied in /usr/share/centreon/www/class/centreonLog.class.php on line 193 I try to execute “sudo -u centreon php /usr/share/centreon/cron/centstorage_purge.php” but i got same error.  Is there anything i can do to solve this bug ? Regards,  Florian

Good morning,Following a full /VAR/LOG disk, my BDD server refuses connections with my central office.From my central office, I can connect to the remote server hosting the database with the correct user/password.How can I reset the user/password pair of the central server allowing connection to the database?

Hello,I'd like to execute, with Dynatrace API v2, a GET request (synthetic - HTTP monitor execution).- Is it possible to perform this with the Dynatrace Centreon plugin ?- If not, is there an other way to proceed ?Thanks,

HelloI have a behaviour that I can't identify.For memory/swap probes I have 2 equivalent services (they have the same service model), but one has graphs that work, while the other does not. What I don't understand is that on the CPU and Load probes, the graphs work correctly.The graph model is related to the service model, so they have the same configuration.Do you have any ideas?

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.

Hi Team,I had successfully installed centreon NSClient on windows server 2019 and modified the parameter in nsclient.in file and add my poller servers IP address like 172.24.XX.XX/32. restarted the nscp service. what is the next step ? unable to view the systems in Centreon Server’s host for monitoring.Please help.  Thanks.

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

Hi everyone,I already post this question but I think it was in the wrong section so I repost it here. I wondered if it’s possible to embed charts related to alerts in side email notification ? (so it also means sending HTML email notifications).For example I know how to export this type of charts from the web UIbut how could I automatically put these chats into notificationI’m also working with CheckMK raw edition on another infrastructure and this is something I’ve got in alerts email notification :For example this from a CheckMK alert email :
