I have been running couple of Newman executions and analyzing the JSON and HTML reports. I’m facing some difficulties in understanding the Metrics that are in the JSON report  
Do we have a description of the metrics available in Newman JSON report somewhere?

example, I’m not sure what this **stream** means:

> “stream”: { “type”: “Buffer”, “data”: [125, 114, 86, 102 …] }

Thanks for your post, and sorry we didn’t get to this sooner. This isn’t the experience we want for our users.

The `"stream"` object is a Node.js `Buffer`, it typically contains the `raw` response and you would need to decode the `data` array using something like `Buffer.from([...]).toString('utf8'))`.
