# 017 — Ntfy.sh alerts (future idea)

> The README lists this under "Ideas... that can be implemented in the future, but
> not now." Not scoped for current implementation — tracked here so it isn't lost.

## Summary

Let users configure matchers of interest and an ntfy.sh channel, and send a
notification to that channel when a matching event occurs.

## Scope (sketch, not final)

- Matcher definition, likely reusing the FilterBar query language
  ([005](005-filterbar-pest-parser.md)) or the metric declaration language
  ([002](002-metric-declarations.md)) rather than inventing a third syntax.
- Ntfy channel config, persisted via settings ([008](008-settings-model.md)).
- Trigger evaluation on log ingest (engine-side, to avoid re-scanning) or on bucket
  update, sending an HTTP request to the configured ntfy.sh channel.

## Depends on

- [008 — Settings model](008-settings-model.md)
- [005 — FilterBar pest parser](005-filterbar-pest-parser.md) (likely, for matcher
  syntax reuse)
