Centreon Infra Monitoring

Hi, We have a distributed centreon 22.10.4 platform.We would like to secure the connections between centreon central (client) and it’s database (mariadb server) by using x509 certificates.We’ve already configured the client.cnf file and the server.cnf file by setting the right path and the right certicate. We have this problem : mariadb sslv3 alert certificate unsuported Do you have any idea about it ? Have you ever tried to secure the connection between centreon central and it’s deported db ? We have x509v3 certificates with the right extension TLS Web Server Authentication for the server and TLS Web Client Authentication for the client. Even if the connection works manually with simple certificates without extensions, centreon shows that : “Access denied for user 'user_'@'HOST' (using password: YES).We would also like to know if centreon handle ssl in the core connection with database ? We’ve seen the db.pm file that does not take into account the eventuality of ssl use. Regards.Seri

Hi, I’m newbie with centreon. I have installed centreon 22.10 in a CenOS7 AWS EC2 instance with the automated script withcurl -L -s https://raw.githubusercontent.com/centreon/centreon/22.10.x/centreon/unattended.sh | sh After postinstalation, I went to the GUI and I saw that the central poller was stoped. I have read and follow this and thiswithout success. /var/log/messages seems clean /var/log/centreon-broker/central-broker-master.log contain errors.Error while reading on socket: End of filefeeder 'central-rrd-master-input-1' error:Attempt to read data from peer LOCALHOST:5670 on a closing socketTCP: Connection refused to LOCALHOST:5670 /var/log/centreon-broker/central-rrd-master.log too[root@yig centreon-broker]# cat /var/log/centreon-broker/central-rrd-master.log| grep error[2023-03-03T11:18:27.163+00:00] [tcp] [error] Error while reading on socket: Operation aborted.[2023-03-03T11:18:27.270+00:00] [core] [info] pool: the latency check encountered an error: Operation aborted.[2023

Hello everyone,I am stuck with my centreon which despite several installations still does not want to start. When I export my configuration, I have no errors but it still remains stopped. So I don't have anything display-wise.I don't really know what to do anymore, because I updated it, restarted it, reinstalled it.If anyone knows what I should be looking for, because the logs don't tell me anything either, I'm interested.Thanks 

Hi,How to set it to CRITICAL(containers_stopped'=4 )?I have no idea how to set the value to show CRITICAL when containers_stopped'=4 in this custom macro. 

Hi,We have a custom script for service discovery which seems to work fine when launched by CLI.[centreon@sli-centreon-c1-qul autodiscovery-pdu-aten-master ]$ perl /usr/lib/centreon/plugins/optnc/autodiscovery-pdu-aten-master/main.pl --hostname=ip_address --snmp-community=centreon --snmp-version=2c --disco-show<?xml version="1.0" encoding="utf-8"?><data>  <label id="1" status="2" name="Alim 1 serveur 1"/>  <label id="2" status="2" name="Alim 1 serveur 2"/>  <label id="3" status="2" name="Alim 1 serveur 3"/>  <label id="4" status="2" name="Alim 1 serveur 4"/>  <label id="5" status="2" name="Alim 1 switch FB"/>  <label id="6" status="1" name=""/>  <label id="7" status="1" name=""/>  <label id="8" status="1" name=""/></data>[centreon@sli-centreon-c1-qul autodiscovery-pdu-aten-master ]$ perl /usr/lib/centreon/plugins/optnc/autodiscovery-pdu-aten-master/main.pl --hostname=127.0.0.1 --snmp-community=centreon --snmp-version=2c -

I have create a poller. At the final of installation , i try to export configuration for the new poller :But an error on moving files appears “Moving files... NOK(Could not write into centcore.cmd.

Hello, I currently facing a problem when I want to install “centreon-plugin-Virtualization-VMWare-daemon” to monitor my ESX. It seems that perl(ZMQ::Constants) is required/necessary to do the installation. I already tried to install perl(ZMQ::Constants) with cpan “cpan ZMQ::Constants” : It looks like ZMQ::Constants is up to date … I checked on internet and it seems like no one got the problem, so I’m really lost at this point. I have installed Centreon on a Oracle 9. I installed packages perl-ZMQ-libZMQ4, perl-VMware-VSphere  Is someone already faced this problem ?  Hope I’ll get answer.  KR, 

Hi, I’m getting the following error message when trying to do an NMAP discovery - what am I meant to do here?! We trust you have received the usual lecture from the local SystemAdministrator. It usually boils down to these three things:     #1) Respect the privacy of others.    #2) Think before you type.    #3) With great power comes great responsibility. sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper Also, this is a brand new install.

Good morning,I have a problem with nmap discovery. I have an error for the lauching. Error: Nous espérons que vous avez reçu de votre administrateur système localles consignes traditionnelles. Généralement, elles se concentrent sur ces trois éléments :    #1) Respectez la vie privée des autres.    #2) Réfléchissez avant d'utiliser le clavier.    #3) De grands pouvoirs confèrent de grandes responsabilités.sudo: un terminal est requis pour lire le mot de passe; utilisez soit l'option -S pour lire depuis l'entrée standard ou configurez un outil askpass de demande de mot de passesudo: il est nécessaire de saisir un mot de passe

Hello everyone,I installed centreon 23.10, and i’m working on retrieving my services, and getting them to work, but there’s a catch : few of my webpages, crucials ones, aren’t accessibles, while they were before. Hosts configuration wasn’t accessible for quite a while, but recently, i had the service configuration, and the whole status details in the monitoring tab. It seems to work, but doesn’t display any services. And it’s not that the services aren’t working either, as you can see on the resources status screenshot.I think it’s a php error, somewhere, but i’ll need the help of someone who know better than me,  how the inner side of centreon work. thanks for the help !

The Centreon Plugins team recently introduced a new fashion of scraping monitoring indicators. It’s called Collection.  These modes could be seen as 'dumb' boiler-plates, allowing you to monitor 'things' over various protocols or APIs while abstracting some of their complexity. Collection modes rely on a JSON configuration file describing the data you want to get and the processing or mapping you may wish to apply. This kind of mode is handy if you are in one of the following situations:You can't find an existing plugin to monitor what you want or fulfill your particular need. You need to gather data from a in-house, black box, or third-party application and transform it to be easier to analyze. Writing (or asking for) a dedicated plugin appears overkill because you simply want to monitor values and apply thresholds over them. Currently, Collection modes are available for: SNMP (check the tutorial) SQL (check the tutorial)In other words, you can use these on any device supporting SNMP

Hi there, I have the next problem:We have the alerts from centreon sent via telegram. The point is that we don’t want that many alerts, we only want those ones we are interested in. So I tried to filter that information, only achieving to filter the performance data (which is not the message telegram sends, telegram send the status information).To sum up, I want to filter the info from STATUS INFORMATION and I don’t know how. I have tried with How to play with Regex - Part II | Community (centreon.com) and part 1 and it has been impossible for me to succeed. I`ve been working with centreon for just a couple days now so I will gladly thank any help. This is what I want to filter 

Hi there, I am working on two version of centreon :Centreon 22.04 on Debian 11 (Bullseye)Centreon 24.04 on Debian 12 (Bookworm)(I am planning to migrate my old system to the new one.) I have a problem on plugins installation.First, it appears on Centreon 24 while configuring it to monitor my hosts, then I noticed it was the same on Centreon 22.. Web : the plugin seems to be installed, but can not be found in “/usr/lib/centreon/plugins”Terminal : the command lead to an error. Actually, it seems that the command is wronge.g. :centreon-pack-network-hp-standard-snmp = KOcentreon-plugin-network-hp-standard-snmp = OK The first command line is provided by Centreon website when you click on “more info” (“i”) of the plugin you wish install. Centreon, is it me or what happenned ?  Julius

Hello everyone,Since the upgrade of Centreon, I have lost the history of my graphs. Before the update, I had set the retention values to 365 days in "Performance Data Management". However, today, I only have 6 months of history on all my graphs.The main issue is that I can't modify the retention on my existing graphs and every day, I am losing data older than 6 months.Has anyone encountered this problem before? How can I recover my full history and ensure that my data is retained for 365 days as originally configured?Thank you in advance for your help.

Hello everyone,I'm currently managing a Hyper-V hypervisor environment with the following setup:I recently activated VM replication between two Hyper-V servers (not all VMs are being replicated).Since setting up this replication, Centreon has been reporting the following critical errors: critical: integration service 'Guest Services Interface' status: -/- critical: integration service 'Heartbeat' status: -/- critical: integration service 'KeyValue Pair Exchange' status: -/- critical: integration service 'Shutdown' status: -/- critical: integration service 'Time Synchronization' status: -/- critical: integration service 'VSS' status: -/- These errors appear to be related to the integration services on the replicated VMs. Could someone please help me understand why these errors are occurring and how to resolve them? I've checked the configuration and ensured that VM replication is functioning as expected.Any insights or guidance would be greatly appreciated. Thank you in advance for your

Bonjour Je voulais faire un upgrade de mon serveur de debian 11 à debian 12. Sauf que ça ne fonctionnait plus. J’ai tenté de supprimer les paquets bullseye de centron pour les forcer à ce resinstaller avec les paquets bookworm mais je n’arrive pas à remettre tous les paquets. Vous auriez une méthode qui va bien ? ou Est-ce qu’il faut que je persévers dans ce sens ?
