… specifically, the thing to deliver alerts from your servers to your phone or whatever. I’m using Discord, because it doesn’t depend on my own infrastructure, and I can make a private “alerts” channel on my private server. But I’d like to switch to something that’s not Discord. I’m using alertmanager, FWIW.
Just be aware that if you’re using the Android client, your phone/tablet will probably at some point put it into deep sleep which will prevent it from displaying notifications. You can (and should) change this in the app settings.
