I have prowlarr set up to handle indexers, and I see under settings -> notifications you can add a telegram bot. I don’t know for sure but I suspect that if you did that and mark notify on health problems, it would probably watch for downstream *Arrs?
I’m basing that guess on the discord bot I have set up on sonarr and radarr, which watches my download clients and alerts me when they’re down
Which stage is “violence against oil executives” because I’m excited for that one
