Recently a co-worker reported sporadic 500-range errors on a website he was performing testing on. I was trying to gather some information on what was happening and wanted to use the “Network” tab in Chrome DevTools to show me the following requests

  1. Only requests to the domain of the specific website (e.g. filter out all 3rd party requests)
  2. All non 200 responses

Step one I knew how to do…in the filter search enter domain:example.com (replacing example.com with the actual domain for the project), however I was unsure how to complete the second step.

Through some Googling I eventually discovered that it is possible to do a negative search by pre-pending the - symbol to the field on which you are filtering.

Putting this all together, I landed on the following filter search

domain:example.com -status-code:200

Here’s a screenshot of how the looks in DevTools when visiting amazon.com.

Hope you find this helpful.
