...are we talking
client side net_graph ?
Because server doesn't have it, next option is
stats command, which print in console.
And it calculate all players together.
Server also doesn't know players fps.
You either take screenshot every second or take a video record last 60 seconds (nVidia have Instant Replay feature).
You can try play in your game, load map:
map de_dust2
Then log console output to log file:
con_timestamp 1; con_logfile myfile.log
Bind command in key:
bind p stats
Hit p key every second.
stop logging:
con_logfile ""
You have file in your game csgo folder, myfile.log.

*edit
From server, you can create SM plugin which collect some data stream of specific player.
I had one bad example for now.
