On the service or host that should send notifications, do you see the notification sent in the time-line ? Or do you see them executed in the centreon system logs (through the web UI) .

If you see it correctly, then it's most likely your command failing at some point, maybe like you suspect the macros or something 

Hi ​@Alexandre Belhomme ,

Thanks for you message !
I see nothing on the timeline regarding the service :(

I check the service conf, it is the same

There is contacts in the “ERP_Team” on both platform, and these contacts do have a valid email adress and notifications enabled (same conf too)

So it seems the issue is on the detection for notifications, not on the smtp configuration.

Can you look at the gorgone and cbd logs, see if there is communication issues between the technical services ? There is something in the engine that should trigger alerts but doesn’t.

Can you also select the service you are refering to, and check the notification tab from the resource status page ? You should see a contact or a contact group listed. If there is not then the issue may be here.

On the gorgone and cbd logs, I do not see any errors regarding the notification.

Yes, there is a group listed with contacts. Example with my account.

I’m not sure what can block here then. I would only see something within those process, i can’t dig further, sorry.

thanks for taking a look :)

I have enable the log as follow :

In the centengine.log, I do see these messages :

<2025-08-19T16:53:59.081+02:00] 0notifications] strace] e455864]  _notification_number _is_notification_viable_recovery: 0 => 0
r2025-08-19T16:53:59.081+02:00] 0notifications] ndebug] u455864] Notifications are temporarily disabled for this notifier, so we won't send one out.

​@Alexandre Belhomme 

I’m stupid … I checked the “hard only” option, the notifications are there …

I still don’t get why I didn’t receive the mail, but we are in the good direction :)

Good, you can resolve this then. Glad you found

​Ok ...

After doing another attempt, I manage to receive a mail from the central, it is where the mail are configured.
The attempt that I made yesterday was on a remote poller …

So I discovered that the remote poller must have a working postfix to sent mail notifications …

I’m sorry, but that doesn’t make sense as it is the central who handle everything and for me, that’s him who trigger the notification and so on … and that sent the notifications mails !

Yeah, i got confused by this, but this is the intended behavior based on their doc.
Configuring notifications | Centreon Documentation

Notification commands are executed by the poller that monitors the resource. You will need to configure the ability to send notifications on all pollers.

I know there was people looking into how to centralise back those notifications, if you want to give it a read. (it is in french)
