不同平台不同版本的iperf结果加时间戳

• 背景

  常用iperf对网络通路进行带宽测试，当需要24小时不间断甚至更长时间的持续测试时，记录过程信息就非常有必要，可在网络出现问题时，根据日志来定位问题发生时段。

Iperf3增加时间戳信息-方法1

#iperf3 客户端服务器均可显示时间戳，iperf3 3.17以上版本支持

Iperf3增加时间戳信息-方法2

#方法2， 使用-T参数，在iperf3客户端 上可用。

Iperf2在windows平台下增加时间戳信息

说明： iperf -e 参数可显示更多信息。

#iperf2 windows
d:\AppGallery\iperf-2.0.9-win64\iperf.exe -s -u  -i 1  | Foreach{"{0}-{1}" -f (get-date),$_}
d:\AppGallery\iperf-2.0.9-win64\iperf.exe -c 127.0.0.1 -t 10000 -u -e -i 1 | Foreach{"{0}-{1}" -f (get-date),$_}

Iperf2在linux平台下增加时间戳信息

#iperf2 linux客户端
nohup iperf -c 127.0.0.1 -t 10000 -u -e -i 1 | while read pong; do echo "$(date +"%Y-%m-%d %H:%M:%S") | $pong"; done | tee -a iperf-$(date +"%Y-%m-%d-%H:%M:%S").log &

#iperf2 linux服务端 
nohup iperf -s -u -e -i 1 | while read pong; do echo "$(date +"%Y-%m-%d %H:%M:%S") | $pong"; done | tee -a iperf-$(date +"%Y-%m-%d-%H:%M:%S").log &
