Or 6 days? + +Netdata's dashboard features a **timeframe selector** to help you visualize specific timeframes in a few helpful ways. +By default, it shows a certain number of minutes of historical metrics based on the your browser's viewport to ensure +it's always showing per-second granularity. + +## Open the timeframe selector + +To visualize a new timeframe, you need to open the picker, which appears just above the menu, near the top-right cover +of the dashboard. + +![The timeframe selector in the local Agent +dashboard](https://user-images.githubusercontent.com/1153921/101507784-2c585080-3934-11eb-9d6e-eff30b8553e4.png) + +The **Clear** button resets the dashboard back to its default state based on your browser viewport, and **Apply** closes +the picker and shifts all charts to the selected timeframe. + +## Use the Quick Selector + +Click any of the following options in the **Quick Selector** to choose a commonly-used timeframe. + +- Last 5 minutes +- Last 15 minutes +- Last 2 hours +- Last 6 hours +- Last 12 hours + +Click **Apply** to see metrics from your selected timeframe. + +## Choose a specific interval + +Beneath the Quick Selector is an input field and dropdown you use in combination to select a specific timeframe of +minutes, hours, days, or months.

At the default timeframe, based on your browser viewport, each +"tick" on charts represents one second. If you select a timeframe of 6 hours, each tick represents the _average_ value +across a larger period of time. + +**You can only see metrics as far back in history as your metrics retention policy allows**. Netdata uses an internal +time-series database (TSDB) to store as many metrics as it can within a specific amount of disk space. The default +storage is 256 MiB, which should be enough for 1-3 days of historical metrics.
