Also, I see the following under poller. Deleting the files in “/var/lib/centreon-broker” did not solve the problem.

Hello, We having an issue with one of our poller. to give you some details of our monitoring infrastructure, its composed of 1 central server with 2 poller on our clients’s site. They are all in the same version 21.10: The most part of time the poller work correctly and do his checking / notification job. But when we lose the whole part of client infrastructure (~70 hosts and ~300 services)  the poller doesnt send the notification on time, also the scheduling part seems to have some problem some host are lock in soft state : Also as you can see in the first screenshot the UI shows that the poller have some latencyFor the notification part we receive 2 mail every minutes , so sometimes we receive the mail for one check one hour after the check changed his state. I checked the centengine.log and i found some interesting things :But i didnt found any interesting topics on the web. We also tried to reinstall the poller … but it didnt solve the problem. The other poller is working correctly

Hi team, Is there a way to monitor a Linux service running under /etc/init.d  ?I have many services running on my PBX and I need to monitor them on my Centreon:  Thank you Regards

Hello,I use Centreon to monitor internal servers and it works perfectly. It is the Centreon server that contacts the targets to obtain the metrics.Now I need to monitor servers across the internet without a VPN connection.I think that in this case it should be the remote servers that send the metrics to the Centreon server. Is it right ?I haven't found how to do this.Can you help me please ?Thanks

Hello, We use the centreon vmware plugin for years now.It works nice with our vcenter 6.5 and our 16 esxi  Here’s the centreon_vmware.pm file %centreon_vmware_config = ( port => 5701, vsphere_server => {            'vcsa' => {'url' => 'https://vcenter 6 ip/sdk',                                     'username' => 'username',                                     'password' => 'pwd'},            'vcsa7' => {'url' => 'https://vcenter 7 ip/sdk',                                     'username' => 'username',                                     'password' => 'pwd'},                        });1; I so did add the vcsa7 entry, then added the same permissions on the vcenter 7 than in the 6 to monitor our new vcenter with the new esxi’s in it But, you see me coming 🙂 it doesn’t workI tried to add an esxi by duplicate an actual one, the changing just vcsa by vcsa7 and i get a UNKNOWN: Container connection problem Any idea about this? What can i check here? Thank you

Hey :DI started a custom view on Centreon, and created a ‘Servers’ hostgroup with a lot of hosts in it.But when I want to create an Host Monitoring widget and when I filter with the Servers hostgroup, the list is empty. It’s not working for any hostgroup. When no hostgroup is provided, it’s working fine and showing the first 30 hosts (no hostgroup).Do you have any idea why is it not working ?Thanks :D Hostrgoups listWidget configurationWidget after applying the hostgroup filter

 Hello, I’m trying to monitor two esxi, but I’ve got an error “UNKNOWN: Cannot find 'HostSystem' object”.When I change the ESXI2(172.16.250.6) to the first in the centreon_vmware.pm config the ESX is monitored, but when I put the ESXi2 on second in this configuration file this is the ESXI2 that is monitored and not the first one, I want to monitor both esxi.Esxi 2 is placed in second in centreon_vmware.pm config: So the ESXI 2 is monitored but not the first ESX:: Service centreon_vmware.pm status: When ESXI 2 is place on first: The ESXi 2 is not monitored this time and its the first ESX that is monitored:%centreon_vmware_config = (    vsphere_server => {        default => {            url => 'https://172.16.250.6/sdk',            username => 'root',            password => 'xxx'                },    },          vsphere_server => {                default => {                    url => 'https://172.16.250.3/sdk',                    username => 'root',           

It appears that if a service is setup as passive and volatile that if a state change occurs, notifications still go out.  The reset of the service does not. My passive check is using NSCA for ingestion. Reoccuring downtime does work but was hoping to use Time periods

Bonjour,Je rencontre actuellement un souci qui concerne la mise à jour de Centreon. En effet, une mise à jour de Centreon était à réaliser, pour l’étape 1 j’ai bien fait un ‘backup’ de la base de données (en suivant la documentation de Centreon), et arrivé à l’étape 2 tout était en ‘loaded’ vert, mais quand je fais suivant il ne se passe rien. J’ai recommencé les manips à chaque et à chaque fois c’est la même chose, auriez-vous une solution ?Je vous remercie d’avance.

Bonjour,nous nous intéressons à Alyvix, un plus étant l’intégration avec Centreon.Cependant, la doc précise ce point: “Le Plugin-Pack Alyvix Server n'est pas compatible avec la version Open-Source d'Alyvix, la fonctionnalité API Rest étant exclusive à la version commerciale de la solution. N'hésitez pas à contacter votre représentant Commercial afin de pouvoir discuter des conditions d'accès. “ On voit bien ici ( https://alyvix.com/service) une offre de souscription, mais quel est le lien avec l’API ?je suis preneur d’une explication car j’imagine que vous le l’avez pas écrit pour rien.Cdtl

Hello ! I’m configuring the dependence settings for my Centreon system. And i have encountered a problem which block me from getting what i want to achieve. Here is a global view of my situation :I’ve set up a Centreon system consisted of 1 main server and 1 poller. The main server supervises the whole central LAN including at least some linux servers. The poller supervises everything outside of the central LAN, basicly remote LANs with some linux servers inside, and routers/ peplinks interconnecting remote LANs to the central one. What i want to do is to set up a chaine of dependency outside of the central LAN, more specifically, a chain such as :poller (inside the central LAN) => router A => peplink B => linux server C (inside a remote LAN)So when peplink B or router A is down, i wish that no checks nor notifications of C will be performed. The problem is, some checks (RAM, CPU, Disk...) of server C is arranged in a service by group manner, as i have a large group of linux s
