regular notification about hosts DOWN

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?

https working on local but not on network

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.

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

Show only % in VCSA Datastore-Usage-Global graph

🇬🇧Hello, Would it be possible to filter the curves used on the "Datastore-Usage-Global" probe? I have 7 LUNs from a storage array to monitor and some local datastores. However, with the information in bytes (B) free/used and in percentages (%) free/used, it gives me 4 times too much content when I want to use the graph. I just want to have the percentage used curves. And if possible, have everything in the same table; otherwise, I can always generate a graph per metric.Thanks 🇫🇷Bonjour, Est-ce qu’il serait possible de filtrer les courbes utilisés sur la sonde “Datastore-Usage-Global” ? J’ai 7 LUN d’une baie à monitorer et quelques datastores locaux. Sauf qu’avec les informations en octets (B) libre/utilisé et en pourcentages (%) libre/utilisé, ça me fait 4 fois trop de contenu quand je veux me servir du graph. Je veux juste avoir les courbes pourcentage utilisé. Et puis dans la mesure du possible tout avoir dans le même tableau, sinon je peux toujours généré un graph’ par métrique.

How to spread/dispatch the checks in a Timeperiod

Hi,We use Centreon 23.10.11.We have e Timeperiod linked to 400 services. This timeperiod is set to run the services everyday 08H-10H.The problem is that the Poller tries to run all of them at 08H00 … which leads to cpu load (on the poller) and also timeouts for some services ….The services are ran locally on the Poller (Not on remote hosts).The services are configured with a ‘Retry Check Interval = 8 minutes and a  ‘Max Check Attempts=8”I juste need that these services to be run once a day but not necessary at 08H exact time.I just want to find a way to get these services execution dispatched (spreaded) in the Timeperiod (From 08H to 10H) …Example:service 1 : run at 08H00service 2 and service 3  : run at 08H01service 4: …. run at 08H04 … etc Any idea ? Thanks ?

How to clone pollers?

Hi guys! do you have any specific instruction on how to configure a cloned poller? This would be very handy for indrastructure taht is distributed in multiple sites. It is also much more convenient to clone a VM than install everything from scratch. What I’ve learned so far:The usual suspects: IP, hostname , host SSH keys copy gorone config (from guil) and past it on the poller if it’s a new poller: configure engine for it on central if you replace an old poller: Gorgone history, mentioned in here This is probably sufficient for checks to run, but for exapmle platform status->poller statistics stays empty for cloned satellites. Anything else we need to know? Thanks in advance!

All my installations (made from scratch following the instructions)have this error. Kind regards

Migration database 20.04 to 24.04

I am in the process of migrating my centreon 20.04 to 24.04 with the "awie" plugin.So I can export from 20.04 all services, hosts, controls, contacts... and import them (.zip format) into 24.04.I have a problem when I try to import all the services, the loading is infinite and only 53 services are downloaded (out of more than 1300).I tried to split the zip format to see where the problem could be. Sometimes the import succeeds, for example when I keep 8000/15000+ lines of code, but only the 53 services are loaded (I check on these lines, there should be about 574 services). I also have the same problem with the verification checks. All other elements are imported successfully. We also tried to restart pollers, services (cbd, centengine, gorgoned, centreon), reboot the server. Nothing changed. Thanks for you helping by advance,
