# Insights Overview

To give you a quick summary of system health, the **Overview** tab provides an overview of your service over the last 7 days. This displays information such as **Total requests observed**, **P90 Latency**, **Errors**, and **Endpoint health**.

From here, you can select points in the graph, compare last 7 days with the previous week, and navigate to individual endpoints and errors.

To learn more about endpoint data in Postman Insights, see [Insights Endpoints](/docs/insights/reference/app/endpoints-tab/). If you haven't, you can [customize your Postman Insights](/docs/insights/customize/). You can also learn how to [debug your endpoints with Insights](/docs/insights/debug/).
