Centreon Infra Monitoring

Hello,Do you know if it is possible to monitor the number of hosts and services monitored by Centreon?Several times while modifying services I made a mistake and services were deleted, if I'm not careful I might not even realize it.I would therefore like to have a graph on this information and be alerted below a certain threshold.Thanks

Bonjour,J’ai ajouté un downtime à 3 machines qui sont sorties du parc pour arrêter les check (et en espérant qu’elles ne seraient plus en “critical” (j’aime quand tout est vert 😁).J’ai donc ajouté des downtime jusqu’en 2200, j’ai vu large (trop), mais après avoir appliqué la conf j’ai mon poller not active et databas updates not active (je n’ai qu’un central).Dans /var/log/centreon-broker/central-broker-master.log j’ai :[sql] [error] mysql_connection: could not store downtime:  Out of range value for column 'end_time' at row 1En regardant ici https://docs.centreon.com/fr/docs/alerts-notifications/downtimes/ je me suis dit qu’il suffisait que je supprime les downtime mais je ne trouve pas le  “Rendez-vous dans le menu Monitoring > Downtimes > Downtimes”Soit je suis cherche mal, ce qui n’est pas exclu, soit je n’ai pas ce menu en 21.04.3Une âme charitable aurait une autre solution ? Directement en bdd ?[EDIT]Voici le même fichier de log complet après un reload :[2023-03-14 19:43:3

Hi!First time posting here, It’s been some time since we had working graphs on Centreon and I’m trying to see if I can make them work again. Here is a summary of the situation : It’s been like this for 6 months. This morning I updated from 22.04 to 22.10 but it’s the exact same thing: I either have “ No data available for this period ” or graphs but without any data on them. I saw other posts from other users and tried the solutions (like adding an IPv4 output named centreon-broker-rrd, see), but nothing seems to work. I appreciate any help :) Thanks!

I’m running the default linux snmp templace but I’m only getting the used performance data, I’m missing the total disk size. EDIT: I’m trying to include the command and output, but as soon as I do my post gets rejected with a 403 error.

Hi,I’ve updated my test server from 22.04.7 to 22.10.1During php-pecl-gnupg update, I have several warning like this: Running transaction Updating : php-common-8.1.12-1.el7.remi.x86_64 1/30 Updating : php-xml-8.1.12-1.el7.remi.x86_64 2/30 Updating : php-pdo-8.1.12-1.el7.remi.x86_64 3/30 Updating : php-mysqlnd-8.1.12-1.el7.remi.x86_64

How do I add custom icons in Centreon? I’ve placed a PNG file in the /usr/share/centreon/www/img/media/ppm/ folder, but it’s not showing in the drop down menu in the “Host extended infos” page.

Hello,I created a service to Monitor the E drive on a few of my Windows computers. There are 3 of them and 2 work fine but the 3rd gives an error.  Any Idea why?

Hello,We have three different Windows domains. We have a user to monitor infraestructure, let’s say ‘Monitor’, defined in all three domains. Password for this user is different in every domain.According to this article (https://docs.centreon.com/pp/integrations/plugin-packs/getting-started/how-to-guides/windows-winrm-wsman-tutorial/#configure-kerberos-on-the-centreon-server), when configuring pollers you create a file called Monitor@keytab ‘to allow reconnection without a password for the reinitialization part’.However, If I repeat the process for every domain, I will rewrite the same file three times. How do I have to do when configuring three different domains with the same user? Do I have to use different users? Can I follow the configuration process you suggest using @USERNAME@+@DOMAINNAME@ when you tell to use @USERNAME@? Will the ‘realm’ command  work fine repeating it for the three domains? I’m not sure about if all commands will work properly.Can you tell me how to do it?Thanks

Good afternoon all,I would like to thanks for all informations which are in this forum. It’s very complete but maybe to advanced for me.I’have a little problem to install centreon.

HiI use Centreon IT-100 Edition, 22.10.5, on a standalone Linux Debian 11.I would like to be able to use the stream connector to send my alerts in Opsgenie.So I followed the documentation here: https://docs.centreon.com/docs/21.10/integrations/event-management/sc-opsgenie/ but nothing is sent to Opsgenie.I double checked my configuration: parameter of the connector, api key value, permission in Opsgenie, access to api url, etc. but all is good.I tried to execute the lua script and no output appeared (normal) so I think all is good for Lua in my system.Here are the lua packages installed:~$ apt list lua* --installedListing... Donelua-curl/stable,now 0.3.0-9.2 amd64 [installed]lua-socket/stable,now 3.0~rc1+git+ac3201d-4 amd64 [installed]lua5.1/stable,now 5.1.5-8.1+b3 amd64 [installed]Then I tried to elevate the logging level to debug for [core] and [lua] in central-broker-master configuration and I saw these messages (filtered) :~$ sudo systemctl restart cbd~$ tail -f /var/log/centreon-b

Hello the community,Nice to meet you.  I am testing Centreon 22.10.5 using remote pollers.Is there any conditions for changing the centreon-engine password? Could I change it with no risk?

Hello,I am testing the new version of Centreon Map (22.10), the problem is that when I click on a map to view it, sometimes it works and displays the map, sometimes it doesn't show anything for a second and returns to the maps list page, so I have to click on the map two or three times to be able to display it.Here are some photos:if I want to display the map named “myMap”, it will display like this for a secondthen it’s rollback to maps list pageI have to repeat the process two or three times to be able to display myMap Thank you for your help.

Good morning, I am monitoring several Windows services with "centreon_windows_snmp.pl". It works fine with the following argument and service name, for example: --service='dcsx'. My question is: why does it show services in critical state if they are running? I have tested with the "Print Spooler" service and it works fine. I have also tested with the DataCore Executive service and even though it is running, it appears as critical. All of this with the same configuration and host.      King regards.

Hello community ! I’ve recently encountered a problem while trying to install the centreon-plugin-Operatingsystems-Linux-Local.noarch component for Linux NRPE3 plugin supervision on an Oracle Linux end-server, using Ansible automation. Here is a fragment of my Ansible playbook code (I use yum_repository as dnf_repository is not yet available in Ansible):- name: Add Yum repository  yum_repository:    name: Centreon    baseurl: https://yum.centreon.com/standard/22.10/el8/stable/x86_64 - name: Install requirements  dnf:    name: “{{ item }}”    state: latest    with_items:      - centreon-nrpe3-daemon.x86_64      - centreon-plugin-Operatingsystems-Linux-Local.noarch While launching the above playbook i got the following error related to the installation of the second component:Depsolve Error occurred:Problem: cannot install the best candidate for the job - nothing provides perl(JSON::XS) needed by centreon-plugin-Operatingsystems-Linux-Local-20230215-164619.el8.noarch I did some research
