|
## Status
|
|
|
|
Proposed
|
|
|
|
## Context
|
|
|
|
We need to send notifications (typically from AlertManager/Prometheus) and we need to receive said notifications on mobile devices for sure in some way, whether it's push messages, SMS, phone call, email, etc or all of the above.
|
|
|
|
## Decision
|
|
|
|
We should go with https://ntfy.sh except host it ourselves.
|
|
|
|
`ntfy` is an open source solution written in Go that has the features we need.
|
|
|
|
## Rationale
|
|
|
|
`ntfy` has pretty much everything we need (push notifications, email forwarding, receives via webhook), and nothing/not much we don't. Good fit, lightweight.
|
|
|
|
## Consequences
|
|
|
|
Pros:
|
|
|
|
- topics, with ACLs
|
|
- lightweight
|
|
- reliable
|
|
- easy to configure
|
|
- mobile app
|
|
- the mobile app can listen via websocket, poll, or receive via Firebase/GCM on Android, or similar on iOS.
|
|
- Forward to email
|
|
- Text-to-Speech phone call messages using Twilio integration
|
|
- Operates based on simple HTTP requests/Webhooks, easily usable via AlertManager
|
|
|
|
Cons:
|
|
|
|
- No SMS pushes
|
|
- SQLite DB, makes it harder to HA/scale
|
|
|
|
## Alternatives considered
|
|
|
|
[AWS SNS](https://aws.amazon.com/sns/):
|
|
Pros:
|
|
|
|
- highly reliable
|
|
- no hosting needed
|
|
|
|
Cons:
|
|
|
|
- no control, not self hosted
|
|
- costs (per usage)
|
|
|
|
[Apprise](https://github.com/caronc/apprise):
|
|
Pros:
|
|
|
|
- Way more ways of sending notifications
|
|
- Can use ntfy as one of the backends/ways of sending
|
|
|
|
Cons:
|
|
|
|
- Way too overkill for what we need in terms of features
|
|
|
|
[Gotify](https://github.com/gotify/server):
|
|
Pros:
|
|
|
|
- simple, lightweight, golang, etc
|
|
|
|
Cons:
|
|
|
|
- Pushes topics are per-user
|
|
|
