Why this helps
During an incident, switching tools to gather impact metrics adds effort when attention is already stretched.
- Keeps an impact check close to the incident context.
- Helps the team distinguish measured impact from assumptions.
- Reduces manual console switching during response.
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 outcome to Notis conversationally.
- 3Use one instruction asking Notis to query relevant ClickHouse data when an incident channel asks a clear impact question and summarize the measurement period and limitations.
- 4Choose Channel Message Received as the trigger and select a channel for run reports.
- 5Test with a real, non-urgent example that names an impact metric and timeframe.
Questions about this workflow
Does it take incident response actions?
