I want to receive a notification if a mirroring repository failed


We use Mirroring Repositories and sometimes it suddenly fails and the mirrored GIT is not gettting any commits anymore.
We want to be notified in slack or email when this happens.
How can I set this up? I tried using the Integration but I dont see an option for this. nor does it send a notification about de mirroring repo’s. other notificiations like ‘new commit’ do work.
