Each of these numbers represents a statistic about your client, network, server, and the performance of your computer. This command is not an essential part of the game and it will not affect your gameplay itself but it is for most people just used to track their data. Many players in Counter-Strike: Global Offensive likes to always have an eye on their FPS count. As you can see in the picture above the first value is “fps: 118” and as you might have guessed represent a live counter of your current frames per second.
The graph also shows you if you are experiencing any loss caused by network issues. The same goes for “choke” and “ping”. You can also see your current network ping on the scoreboard but it is not as accurate as of the one in the graph. It is also possible to see the tick rate of the server. In the picture above the server is a 64tick server.
