1. 统计依据

根据xchain.log中的txCount进行统计，如日志

t=2021-06-21T19:24:51+0800 lvl=info msg="start to confirm block" module=xchain blockid=649a6f7848e7103aa64f0b7c102291d972c7485717ebfd03a4c561d3e669ae54 txCount=1

 2. 使用

bash get_tps_from_log.sh xchain.log 21:21:28 21:21:58

3. 统计脚本get_tps_from_log.sh

#!/bin/bash
function Usage()
{
    echo "Usage:"
    echo "bash $0 log_file_path start_time end_time"
    echo "bash ./node_side/xuperchain/get_tps_from_log.sh ../logs/xchain.log 20:50:00 20:51:30"
    exit 1
}
