A Stream is a tool that you can create, which provides customized, specific ways to collect data proactively through time, and persist that data in a way that’s easily accessible.

By default, Lightstep displays all data for a Stream from the last 24 hours. You can change that time period, as well as filter the data by errors, percentiles, and duration.

When you create a stream that's based on a query or based on a specific operation, Lightstep receives data from your Satellites and stores statistics and example traces related to the stream to ensure you always have data from 0 to p99.9, including outliers.
