iperf 2.1.9 bidirectional test cant figure out the server-client flow

I'm trying to calculate the throughput of the server during the bidirectional test. I have a python script that basically scrapes the data out of the logs. But the problem is I'm not able to figure out which one is the server-client communication and which one is client-server.

[  2] local 10.233.143.159 port 5001 connected with 10.233.143.141 port 59914 Client connecting to 10.233.143.141,
 UDP port 5001 Sending 1470 byte datagrams, 
IPG target: 560.76 us (kalman adjust) UDP buffer size:  224 KByte (default) 
[ *1] local 10.233.143.159 port 40499 connected with 10.233.143.141 port 5001 (reverse)

this is from the server log. Cant quite figure out which is which.

 Client connecting to 10.233.143.159,
 UDP port 5001 Sending 1470 byte datagrams, IPG target: 560.76 us (kalman adjust) 
UDP buffer size: 64.0 KByte (default) 
[  1] local 10.233.143.141 port 65245 connected with 10.233.143.159 port 5001 
[  2] local 10.233.143.141 port 5001 connected with 10.233.143.159 port 34470```

this is the client log. I just want to know the server-client communication from the above given logs.

I tried to use -r instead of -d but got "connection reset by the peer" . So that didnt work out as well. \*\*Can someone help out??PLZZ \*\*

The asterisk indicates the traffic flow is reversed. Also, use -e or --enhanced-reports for outputs with more information.
