The gdbinit file includes commands to start tracing:
```
mon esp sysview start file:///tmp/heap_log.svdat
# For dual-core mode uncomment the line below and comment the line above
# mon esp sysview start file:///tmp/heap_log0.svdat file:///tmp/heap_log1.svdat
mon esp sysview_mcore start file:///tmp/heap_log.svdat
```
When program hits breakpoint at `heap_trace_start`, in single core mode, trace data will be saved to `/tmp/heap_log.svdat`. In dual core mode, there will be two trace data files, one for each core. `/tmp/heap_log0.svdat` and `/tmp/heap_log1.svdat`
When program hits breakpoint at `heap_trace_start`, trace data will be saved to `/tmp/heap_log.svdat`. The `esp sysview_mcore` command uses the SEGGER SystemView multi-core format, so a single file holds the trace for both single- and dual-core targets.
Tracing will be stopped when program hits breakpoint at `heap_trace_stop`.
3. [SEGGER SystemView tool](https://www.segger.com/products/development-tools/systemview/). By default SystemView shows only numeric values of IDs and parameters for IDF's heap messages in `Events` view. To make them pretty-looking you need to copy `SYSVIEW_FreeRTOS.txt` from the project's root directory to SystemView installation one.

The script auto-detects the multi-core capture format and processes both cores from the single file, so the same command works for single- and dual-core targets.
Below is the sample scripts output.
