Live tail

Overview

The live tail functionality within the data hub gives development teams a single place to view and query all impression and event data. With live tail, development teams can,

• Add query criteria to refine the stream of impressions and events
• View impressions and events in real-time
• View raw JSON payload for debugging in Split and 3rd party integrations

This feature allows teams, for instance, to check if a split is being evaluated properly or events are being received from data integrations.

Query impressions

After installing Split’s SDKs and setting up a split, impressions will be generated via the getTreatment call. To view these impressions in the live tail,

1. Navigate to the data hub icon in the navigation
2. Select which data type to view, impressions will be selected by default
3. Click query
4. Impressions will begin flowing
5. Pause or resume paying data at any time
6. Apply column headers as filters by clicking add query criteria
7. Once selected click query again

The live tail can also be accessed on the split page under the live tail tab, where impressios will automatically be filtered down to that specific split.
