Why this helps
When several requests arrive at once, it can be hard to remember which data question needs attention first.
- Provides a lightweight way to distinguish selected questions for follow-up.
- Keeps the priority signal attached to the original message.
- Helps reduce mental tracking of outstanding metric checks.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickHouse to Notis once through the portal.
- 2Create an automation in the portal, or describe the result to Notis conversationally.
- 3Use one instruction asking Notis to query ClickHouse for a clear metric question marked with a chosen reaction and reply with a concise result and period.
- 4Select Message Reaction Added as the trigger and choose a channel for run reports.
- 5Test by adding the chosen reaction to a real, answerable priority metric question.
