# Performance Dashboard

The Performance Dashboard page of the Tunnel Analytics application provides a configurable set of saved charts that visualize the performance data of connected devices.

Setting a value you want for Past, Interval*, Date & Time Range Filter fields helps you to see the visualization of the performance data for that specific time interval and date.

You can adjust the data point granularity using Interval*.

To look at a smaller time intervals, choose a smaller value for Interval*.

For example, to see a data point for every hour in the past one day, set Past to 1 day, Interval* to 1 hour.
