篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了百度区块链 xuperchain 节点端 tps统计脚本相关的知识,希望对你有一定的参考价值。

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
}


log_file="${1}"
if [ $# -eq 1 ];then
    if [ "${log_file}"="-h" ]||[ "${log_file}"="--help" ];then
       Usage
    fi
fi
if [ $# -lt 3 ];then
    Usage
fi

start_time="${2}"
end_time="${3}"

               started=1
               statistic_start="${time}"
            fi

            if [ $tx -gt 1 ];then
                # Every 3 seconds, xuperchain makes a block by default
                # In each block, there will be a TX, which is a transaction to save a reward for miners
                txTotal=$((txTotal+tx-1))
                statistic_end=${time}
            fi

         done

done

    tps=$(echo "scale=1;${txTotal}*1000/3" | bc)
else
    tps=$(echo "scale=1;${txTotal}*1000/$delta_time" | bc)
fi

echo "the unit of execute_time is ms, the unit of tps is tx/s"
echo "[tps_summary],total_transactions=${txTotal},execute_time=${delta_time},tps=${tps}"
