Hardware counters are not supported with Headless Mode.
You should delete the hardware counters configuration file before starting a headless trace, otherwise your application will hang until terminated.
Headless mode can be used to perform a trace on the target device without a connection to the host GA application.
In this mode, trace files are stored in a local directory on the target device.
There are two ways to use headless trace mode: using a global configuration file, or by using the daemon in headless mode.
You can also use Headless Mode to trace a target device from the host machine, without the host's GUI.
The main difference between using the host and target-side headless modes is where the trace output is stored.
The host Headless Mode can only save traces to the host machine, and the target Headless Mode can only save traces onto the target device.
The interfaces for each Headless Mode are also slightly different.

Be aware that exporting assets from an existing trace file can only be performed on the host.
