Triggering Profiler for Ajax Requests
Ajax requests require extra steps when triggering the Profiler.
With help from Chrome or Firefox Network developer tools tab, you can export any request as cURL command and paste that after the "tideways run" commandline invocation to trigger a trace.
Instead of triggering the Profiler on a single page with the "Take Profile" action, you can activate the Profiler for a period of 15 or 60 seconds by clicking the dropdown arrow next to "Take Profile".
This will include Ajax requests made during this period.
See the Trigger from Browser documentation page for details.
