We have a service group called CPU which triggers an alert when Windows Servers CPU is “critical”. Where can I specify the amount of time the CPU must be “critical” before alerting? Right now, it’s kind of annoying because if the CPU spikes for even a minute a notification triggers. I prefer the notification to only trigger if CPU spikes and remains spiked for over 15 minutes. 

Bonjour,Est-ce que c'est possible de réaliser des downtime via api v2 sur des Pollers comme en api v1 ? si oui comment procédé ?Cordialement

Bonjourcela fait maintenant quelques jours que je rencontre des difficultés afin de configurer centreon. Du coup, j’ai préféré faire simple et recommencer de zéro en supprimant tout et en réinstallant. Cependant je rencontre un problème lors de l’étape d’installation du repository Centreon. Infos: Je suis sur Oracle Linux 8, tout est bien installé (mysql etc) j’ai suivi les étapes de la documentation cependant vous verrez dans mon screenshot le problème:cette erreur il me l’a fait plusieurs fois d’affilé et ce pour n’importe quelle commande incluant “dnf install -y” + le nom d’un package centreon. J’ai redemarré le serveur plusieurs fois mais rien n’y fais. Vous remerciant d’avanceCordiales salutations

Hello,I have a question about the last version 23.04.We will reinstall our central servers on RH8. (Web server, DB server & broker server)But, actually, we can’t reinstall or upgrade right now our pollers on RH7.x On the new repositiry, I saw that no el7 packages are available for 23.04… So, can pollers running RH7 with version 22.10 communicate with a central server running RH8 and version 23.04 without problems?

Hi,I started to use the new WebUI for the support : https://support.centreon.com/It seems there is no way of formatting a message. No way of using italic, or fixed width. Am I missing something?Also, I can join a file but can’t directly paste an image.I opened a ticket (#58264)  by sending a mail, the inserted image is there but all the formatting is lost.Will it be improved? Currently it sucks. Sorry for the language but it really does :(

Hello,We have created a custom script that generates certain perfdata:OK: runningPiTcpSocketFibers < 200 | 'runningPiTcpSocketFibers-1'=2;;0:200;0; 'runningPiTcpSocketFibers-2'=2;;0:200;0;The problem is that the values ​​of the perfdata that should be 2 and 2 when they appear in the graphs come out with decimals and not as integer values. We don't understand where those values ​​come from or what calculations you are doing to get them. We have tried to configure it through Monitoring > Performances > Curves but we have not succeeded either.Can you help us? Best regards,

Hello,When I do the "vgs" command I realize that Vfree is at 0I've tried several ways to enlarge it but I can't. I enlarged the space on the vm too.I'm on VMware.

I upgraded my single central server environment to the 23.04 release.After upgrading everything seems to be running fine but the Extension Manager page will not load.Everytime i try to access the menu i just receive an empty blank page with no text or any other information.Also I still have a problem that was around when I was running the 22.10 release. The Host Key verification for the broker stats check is missing or not valid. How and why do i need to verify my Host Key when the central server is monitoring itself? In the doc it says you can skip doint the host key verification. Am I missing something here.

Hello Team, We use Netbox mainly as an inventory application to store all our equipment details.I would like to know if there is a way to synchronize the newly added equipment automatically to Centreon using API. My scenario;I add a device on Netbox with the name, IP, host category, etc.Use Netbox API to Sweep the device list and grep the latest device added on Netbox.Using the result above, we push the data to Centreon which then the later will add the device as HOST and then autodiscovery feature will add all the SERVICES automatically. Is that possible please?If yes, do you have such plugin available in Plugin Pack? Thanks.Regards,M.B

Hello everyone,We are currently trying to setup a centreon monitoring HA cluster on debian 11 and are currently trying it out in our test network. We installed 1 central server, 1 secondary and a poller/quorum deviceWe made the decision to install the HA feature described as in the official centreon documentation, unfortunately we ran in some trouble. The PCS cluster and all its resources look like they work correctly but the configuration of the primary node doesn’t get failed over, this means that in practice we have 2 different centreon installations instead of the clustered HA configuration that we want aka split brain.The secondary node does become the primary node but it doesn’t have any of the config or hosts that we added on the primary.We would really appreciate if any of guys could point us to the right direction.I’ll post some examples of what I mean below.Output of crm_mon -fr on node-a while node-a is also the master serverI added a test host on node-aI failed the cluster

Bonjour,j’ai supprimé des services d’hôtes mais je les vois toujours dans le statut des ressources.J’ai exporté la configuration des collecteurs plusieurs fois.Les compteurs de la page des ressources me montrent 52 services mais il y en a 140 affichés :Les 52 sont ceux des collecteurs et du Central. Les autres sont des services que j’ai supprimés et ils sont orphelins : ils n’ont pas de parent.J’ai aussi supprimés tous les fichiers cfg sur les pollers, mais rien n’y fait;Merci pour votre aide.Cordialement.Alain

Hello, I am using Centreon DSM and I noticed that sometimes DSM execute two check command to write two different traps (alert) into the same slot at the same time, therefore the second check overwrite the status of the first one. Any ideas why I am having this behavior ?Thank you.Best regards.
