Monitor Fabric OneLake transformations - Cognite Docs

The features described in this article are in public preview and may change.

After a transformation that uses ext_onelake runs, review metrics in Cognite Data Fusion.

View Run history

Open Transformations.
Open the transformation.
Select Run history.

For OneLake reads, Run history can show metrics such as:

onelake.<source>.<table>.rows.read
onelake.<source>.<table>.bytes.read

You also see the usual transformation upsert and job status metrics.

What not to expect

Volume, concurrency, and throttling limits for this path are Cognite-managed. If jobs hit enforced defaults, contact Cognite Support. Do not look for customer-facing concurrency or executor dashboards for OneLake.
