The only way to do that would be for you to remove the 12810 and 20823 contacts from the hosts/services so they don't try to send.

Notifications are logged as they are supposed to be, there's no way to turn them off without likely modifying the source code (not recommended) as it's meant to log those.

You're essentially saying you don't want it to log notifications for some contacts, the functionality to do that doesn't exist, you can create a feature request for them to add that here but it's not currently possible to disable that logging:

Code: Select all

Please keep in mind that the decision to implement the enhancement is at the discretion of our development team.

@ssax

Thanks for sharing details.

Can not remove contacts,we are using Hostgroup and Servicegroup feature.

Because of 1k hosts and 72k+ services, we trying to avoid this notifications.

You have any another way to stop or redirect this notifications.
