Centreon Infra Monitoring

Hello,We would like to migrate our AlmaLinux 8 machines to 9During the migration, an inibitor is present: The centreon-release-22.04-3 package is signed in RSA/SHA1, which is no longer supported by AlmaLinux 9.This package is the only one on the list not to be signed in RSA/SHA256.So we wanted to know if it was possible to have the package signed in RSA/SHA256, or if it will be in the next update? And why is it the only one that isn't yet?Thanks

Hello my fellows, I have migrated all of my centreon to the newer version, and i’m still having some bits and bops to fix. Among this, i have the centreon_plugins.pl file, who’s using the centreon::plugins::script Perl module.Which appears, not only not to be installed, but to be absent from the old machine too. which mean, i have first, no way to copy and transfer it to the newer machine, and second, no idea how it was working before.I tried to install it with CPAN, usin cpan install centreon::plugins::script, and cpan couldn’t find the module.I also looked for it a bit online, if i could find any file from which to install it, but didn’t found one. Have a good day !

Hi all At last, the last day of the week, to end up with yet another galley...I cloned my centreon vm and updated the clone from 23.10 to 24. I followed the instructions for this update.But now I don't have any hosts or services appearing.Why ?The original in 23 works fine …I restarted services ..   

Hello everybodyAfter having troubles with High CPU on the Central Server ( see Centreon 24 - gorgone-proxy High CPU usage), I have disabled the nodes modules in the 40-gorgoned.yaml file on the Central and the CPU is back to low usage.As far as I have seen since a week, all my pollers are running well and checks are ok.Is there some collateral damages to disable the node module ?My pollers are using revese flow to the CentralRegardsPierre

Hi,Here we use centreon 23.10.11…Do you have any idea on how to collect statistics on the pollers ? : ideally : would like to find the total number of active service checks executed per day (Ex yesterday).This command below gives some info about the total number of hosts and services … and inter-check delay  .. etc .. But not the total number of checks …:“centengine --test-scheduling /etc/centreon-engine/centengine.cfg”?Thanks 

Hello,I have configured services by host groups (some redundant services for certain types of servers according to my host groups). When I display the top/bottom widget on the dashboard, I only see one line with the name of the running server instead of having a list of values.How can I resolve this issue without having to go through each of my hosts to recreate the service?Thank you in advance. An example of a relatively broad value that points to several dozens of hosts. 

I would like to request a new License for our Centreon, our one is no longer functional after changes to the infra:  

Hello, I would like to know the total ammount of traffic of my application, so i’ve created a meta service who sum the output traffic of my three serversi’ve created one more for input traffic ( i donc know how i can do it with one like current traffic service)The issue is that sum isn’t considered as b/s units but simple integer so i can read 1b in graph legends for 1Gbit/s speed.How can i specified the units (or force it to use same units as services used for sum) for meta-service ? Best-regards

Hello,I'm encountering some issues with the Centreon dashboard.When I create a dashboard and choose the "status grid" widget type, I notice that some services are in "warning," "critical," or "unknown" states within the dashboard.  However, in Centreon, all services seem to be in an "up" state. Could you help me resolve this issue?  

HiI have several critical services but I don’t see them (number in the top) : Any idea ?thanks

Hello I am looking to integrate a theme in centreon MBI to customize the color of my reports. I added the.css file in /usr/share/centreon-bi/Resources/CSS but I can't find it on the Centreon web interface.  Has anyone ever tried to customize the colors of the report templates?Maybe I didn't put my CSS file in the right folder?Thank you in advance

Hello everyone,I've set up a 4-node HA architecture (currently in version 23.04.19) under debian.I've noticed that the backups don't work at all. Looking at the https://docs.centreon.com/docs/23.04/administration/backup/ doc and the /etc/cron.d/centreon file, nothing is specified. I also looked at the /etc/centreon-gorgone/config.d/cron.d/10-centreon-ha.yaml file and found nothing about this.Am I the only one with this problem?Bonjour à tous,J'ai mis en place une architecture HA 4 nœuds (actuellement en version 23.04.19) sous debian.j'ai remarqué que les backups ne font pas du tout. En regardant la doc https://docs.centreon.com/docs/23.04/administration/backup/ et le fichier /etc/cron.d/centreon rien n'est renseigné. J'ai regardé aussi du côté du fichier /etc/centreon-gorgone/config.d/cron.d/10-centreon-ha.yaml rien à ce sujet.Suis-je le seul à avoir ce problème ?

Hi,I have to migrate an old Centreon 22.10.9 installation on Centos 7 to a new one on Alma Linux 8.The following licenses are installed:[root@cntcentral license.d]# ls -l /etc/centreon/license.dtotal 16K-rw-r----- 1 apache apache 1.1K Jul 20  2022 bam.license-rw-r----- 1 apache apache 1.1K Jul 20  2022 epp.license-rw-r----- 1 apache apache 1.1K Jul 20  2022 map.license-rw-r----- 1 apache apache 1.1K Jul 20  2022 mbi.license The new installation was created to substitute the old one, but it has not licenses yet;is it possible to transfer the old licenses to the new installation?Regards,Egidio

Problem:Every morning at 7am Centreon sends a notification (including to our ticketing system) that certain hosts are down. However, the hosts are not actually down at that time, and there is absolutely no “down” entry under “timeline” for the affected hosts at 7am, but there is one at 4:33am with 3 tries.Question:Could it be that the notification is delayed? If so, where can I check that? Related problem:No host UP notification is sent out, so the ticket does not get automatically closed either. What could be the reason?

Hello,when I'm in http, it works normally locally and on the network.When I switch to https, it works locally but not on the network.If I leave the possibility of connecting via http, I can therefore connect everywhere via http and only locally via https.I can't find the solution anywhere.Does anyone have an idea?THANKS.

Hi,I’ve updated my Centreon HA servers from 23.04 to 24.04, but since then I have 2 problems :- I can't reload the configuration from the Pollers > Export configuration menu.With the help of this topic: upgrade 22.04 to 22.10 : many php mwarning with php-pecl-gnupgI get this error:I found this message in the log file /var/log/centreon/centreon-web.log[2024-07-09T12:11:31+0200] [ERROR] [Centreon\Application\Controller\Configuration\MonitoringServerController:229]: Generation error on monitoring server #6: Authentication token expiredI haven't found anyone with the same problem and don't know where to look to fix this token problem. - cron jobs managed with gorgone no longer run since the updateI received alerts for partition tables that were out of date and checked the logs. > I've had errors with the autodiscovery module, which we don't use, so I've disabled it by renaming the yaml configuration files to .disabled.2024-07-09 17:31:55 - ERROR - [autodiscovery] -class- host discove

Hello,I tried SNclient+ and I will share what I found with this short review.My thirst thought is that SNClient+ is mainly for Windows host.s Why ? Because I failed to installed it from Debian 5 to Debian 11 included. The Debian packages are broken on all theses releases, you can’t install it, it will throw an error.The answer from the team was if it’s not working you can try to recompile it from sources.It more sunny on the RedHat side because the RPM is valid (and tested) on RedHat 7 and 9 (I didn't test it on RH8).Also, only a unit for Systemd is included, no Init script.On the Windows side, it’s unclear on which version we could run it.I successfully run it on Windows 2019 but the SNClient+ team don’t give a list of supported OS :https://github.com/ConSol-Monitoring/snclient/issues/48 I tried some check with «check_nrpe» as I’m used to with NSClient++.Some are identical, like theses :$ /usr/lib64/nagios/plugins/check_nrpe -H 10.128.10.7 -c check_drivesize -a Drive=C: ShowAll MinWar

I am getting an execution error when scanning linux hosts with NRPE. No issues on the Windows hosts. Using 23.10

Hello,I am trying to create a MetaService with a SQL Matching selection, but I can not find in the documentation nether on the internet, an example of it. Moreover, I can not find the SQL structure definition to try with it. Can anyone give some guidelines for this? Thanks in advance.Regards, Lluís Clavaguera

Hello everybody,I have installed a Centreon 24.04.2 Central server with several pollers.I use the  ZMQ revese flow from the pollers to the Central.I have enabled TLS encryption (forced to “Yes”) with self made certificates on the Broker configuration for the communications between pollers and the Central (Input on the Central and Output on the poller).Everything is Green on the Poller in the GUI. I can Reload/restart/DoCheck on the poller, All work well.However, I have noticed High CPU (99%) usage for the gorgone-proxy process on the Central.We have and old Centreon 21.04 also with several pollers and have no problem of CPU.Do I have missed something ? Or Did I make something wrong ?Thank you for your answer.Best RegardsPierre

Hello,Does Centreon have to use Postfix to send email notifications? If I don't use Postfix, is there another way to send email?
