A WebSocket of every alert your fleet has ever raised

Forty containers across three projects. Each one's monitoring crons fire notifications to its own notification server. Each server keeps history.

You want one place to ask "what alerted in the last 24 hours, anywhere?" You don't build a SaaS. You curl: GET /api/v1/notifications/{display}?since={timestamp} against each container, in a loop, in a small aggregation script. Or you open WebSockets to all forty in a dashboard container and merge the streams.

The history isn't a separate billing line. It's already in the notification server, sitting in the same container that fired the notification. Forty containers means forty histories means forty curls. Pull, sort by timestamp, render.

Datadog charges per host per month for this. Hoody charges what the boxes cost. The retention is "until the container is deleted."

The audit log isn't a feature you bought. It's the default.
