-Segment generates reports about each sync to your data lake so you can monitor sync performance. The sync health page provides information about trends in volume synced to your data lake over the last 30 days and the sync history provides detailed information about the syncs preformed on the data lake over the last two days. The sync data for both reports updates in real time. 
+The Segment Data Lakes sync history and health tabs generate reports about data syncs so you can monitor the health and performance of your data lakes. These tools provide monitoring and debugging capabilities within the Data Lakes UI, so you can identify and proactively address data sync or data pipeline failures in real time.
