`generate_tracing.py` is used to generate `google trace viewer` format trace, but how to get original log file

I run `perf_llama3_8b_tp1_pp2.py`, the output is 

llama3_8b_a100_pcie_bf16/
├── base_info.json
├── compute_result.json
├── mem_result.json
├── model_config.json
├── strategy_config.json
├── system_config.json
└── model_arch

It seems that no file match the format which  `generate_tracing.py` needs, so how to get original log file?
