我正在使用 iPerf3 来测量两个远程设备之间的吞吐量。我的 iPerf 命令的输出如下：

对于每条输出行，我想在前面添加一个时间戳。
答案1
您可以使用 iperf3 的 -T 选项将字符串添加到 iperf 每行的开头，但不幸的是，如果该字符串包含命令（例如date），它将仅使用该命令最初运行时的日期。
因此，缺少脚本来执行此操作的唯一方法是快速而肮脏的 for in 循环，一次运行 1 个数据包的 iperf：
┌─[root@Fedora]─[~]─[03:25 pm]
└─[$]› for i in {1..30}; do iperf3 -c 192.168.0.1 -i 1 -t 1 -T $(date "+%H:%M:%S ") | grep -A1 Interval | grep -v Interval ; done
15:26:26 : [ 4] 0.00-1.00 sec 8.23 MBytes 69.0 Mbits/sec 8 271 KBytes
15:26:26 : [ 4] 0.00-1.00 sec 8.23 MBytes 69.0 Mbits/sec 8 sender
15:26:27 : [ 4] 0.00-1.00 sec 12.4 MBytes 104 Mbits/sec 219 733 KBytes
15:26:27 : [ 4] 0.00-1.00 sec 12.4 MBytes 104 Mbits/sec 219 sender
15:26:29 : [ 4] 0.00-1.00 sec 12.5 MBytes 105 Mbits/sec 101 673 KBytes
15:26:29 : [ 4] 0.00-1.00 sec 12.5 MBytes 105 Mbits/sec 101 sender
15:26:30 : [ 4] 0.00-1.00 sec 14.0 MBytes 117 Mbits/sec 0 1.05 MBytes
15:26:30 : [ 4] 0.00-1.00 sec 14.0 MBytes 117 Mbits/sec 0 sender
15:26:32 : [ 4] 0.00-1.00 sec 12.4 MBytes 104 Mbits/sec 29 566 KBytes
15:26:32 : [ 4] 0.00-1.00 sec 12.4 MBytes 104 Mbits/sec 29 sender
15:26:33 : [ 4] 0.00-1.00 sec 14.0 MBytes 117 Mbits/sec 2 729 KBytes
尽管使用这种方法，这当然意味着您最终不会得到总体平均结果。我希望这有帮助。

作为iperf3.9，--timestamps添加该标志是为了允许预先添加时间戳：
