Get a list of connected clients in TCP mode

Configuration Samples

Hello everyone

I’m using HAProxy in TCP mode and would like to have some command line to query HAProxy process to get a list of current connected clients.

My clients have sessions for hours and i’d like to monitor that. I’ve been reading forums and documentation but i can’t find anything like this.

Any hint?
Regards

The management guide explain this, it’s show sess on the admin socket:

Thanks lukastribus, but the output i get with show sess is this:
0x7fba28027f40: proto=unix_stream src=unix:1 fe=GLOBAL be= srv= ts=00 epoch=0x7 age=0s calls=1 rate=1 cpu=0 lat=0 rq[f=c08002h,i=0,an=00h,rx=2m,wx=,ax=] rp[f=80008000h,i=0,an=00h,rx=,wx=,ax=] s0=[8,200008h,fd=13,ex=] s1=[8,204018h,fd=-1,ex=] exp=2m

I’m ignorant on what to do next, since I’m looking for something like this:
Remote IP Backend server Session time Session bytes
x.x.x.x 1.1.1.2 50m 4343243 kb

Regards!

As the output indicates, this is not an IP socket, but a unix socket. Unix sockets don’t have remote IP addresses.

As the documentation says:
