Get ClickHouse answers to metric questions in Slack
Ask about a number in Slack and let Notis check ClickHouse, then summarize the result in plain language.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Why this helps
A simple metrics question can trigger a chain of context switches to dashboards, SQL consoles, and follow-up messages.
- Keeps routine data questions close to the conversation that raised them.
- Provides a consistent summary with timeframe and relevant caveats.
- Reduces repeated manual dashboard checks.
Setup
Build it in a few focused steps.
- 1Connect Slack and ClickHouse to Notis once through the portal.
- 2Open Automations and create a new automation, or tell Notis what you want conversationally.
- 3Use one instruction: when a channel message asks about a metric, query the relevant ClickHouse data and summarize the result in Slack.
- 4Select Channel Message Received as the trigger and choose a channel for run reports.
- 5Test with one real metric question and check that the answer reflects the requested period.
Questions about this workflow
Does this workflow answer every Slack message?
The prompt tells Notis to act on channel messages that ask about a metric. It should ignore unrelated conversation.
Can it explain where a number came from?
Ask Notis to include the query timeframe, the result, and any assumptions or limitations it can identify.
