# Updated summary page for Materialized Views

Published Materialized Views now have a summary page showing various details and metrics, such as their processed data, duration and errors, as well as a visual display of the Materialized Views data flow lineage.

When you publish an API Endpoint in Tinybird, you can access a summary page via the UI to see the Endpoint's requests, latency, errors and access its logs. It's a great way for an engineer to quickly understand an Endpoint. However, when publishing a Materialized View, these details were only available by analyzing the data in the Services Data Source, which takes a little more effort. The new Materialized View summary page makes the most important stats available immediately for quick monitoring.
