Here are the tricks :
use socat to catch unix socket(need to restart clients that connected to the socket)
1,download socat:
wget http://192.168.0.254/misc/asi22/sandy//socat/socat-1.7.4.3/imx6/bin/socat
wget http://192.168.0.254/misc/asi22/sandy//socat/libreadline.so.6
2,establish a proxy that can catch data by wireshark from lo
here are the commands:(sudo first)
mv /tmp/PCMGR_UI /tmp/PCMGR_UI.original
./socat TCP-LISTEN:8089,reuseaddr,fork UNIX-CONNECT:/tmp/PCMGR_UI.original
./socat UNIX-LISTEN:/tmp/PCMGR_UI,fork TCP-CONNECT:127.0.0.1:8089
3,start catch logs(directly output)
./tcpdump -i lo -netvv port 8089
tips:netstat can only display server PID, so need to check which client needs be restart.

mv /tmp/PCMGR_UI /tmp/PCMGR_UI.original这一步操作，实际上是将sock文件移动，从而可以新建一个同名的sock文件供Client使用，实际上Server端仍然在监听该Innode。
