Actually there is an option to test the notification system with Proxmox VE 8.1.3I also found myself in need of a way trigger a noteworthy event without actually bringing anything down. In my case, backups notifications are working, but not disk errors, they seem to be on separate channels.
PVE should include a way to test notifications. Nothing works until they are tested to be working.
