### 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 ##
