See channel activity when an event arrives
Use an incoming Ably event as the cue to check recent channel volume in ClickHouse and share a short summary.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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
Checking channel activity manually means switching tools and rebuilding the same context each time.
- Get a current activity summary when a webhook arrives.
- Reuse a defined query instead of checking dashboards manually.
- Include channel context from the payload when available.
Setup
Build it in a few focused steps.
- 1Connect Ably and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Tell Notis which ClickHouse query to run for the channel and time window, and how to summarize the results.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real event and verify the query returns the expected channel data.
Questions about this workflow
Does the workflow calculate a baseline automatically?
No. If you want a comparison with typical activity, provide the baseline or query a table that contains it.
What if the webhook does not include a channel name?
The query needs another way to identify the channel, such as a fixed value in your instruction or an available ClickHouse data source.
