Why this helps
Discussion activity is easy to overlook when it is spread across Canvas and separate analytics views.
- Review related activity without manually opening analytics first.
- Summarize only signals present in the queried data.
- Keep missing context visible instead of guessing.
Setup
Build it in a few focused steps.
- 1Connect Canvas and ClickHouse once in the Notis portal.
- 2Create an automation and describe the discussion activity question in one instruction.
- 3Ask Notis to query relevant ClickHouse data and summarize available context for the new message.
- 4Pick New Canvas Discussion Message as the trigger and choose where reports go.
- 5Test with one real discussion message.
Questions about this workflow
Can it infer student engagement from a message alone?
No. It can summarize relevant records returned from ClickHouse, but engagement measures and identity links must exist in the data.
Can it read the full discussion thread?
The listed ClickHouse action queries ClickHouse. This workflow should be instructed to analyze ClickHouse data available for the discussion context, not to assume the query action fetches Canvas thread history.
