The overview page in Search Console shows a summary of your performance on Google Search.
Visit this page to see a summary of your most important metrics and notifications, including search performance and index coverage. If your property has enhancements such as rich results, or is considered an online merchant, you will also see information about those features.
The Performance chart includes data from both Search and Discover (if you have any data for each). If you do not have any Discover data, the chart will also include preliminary Search data (very recent data).
