If you see plots in the Plots section of the Farm page in the GUI - your plots are being farmed. You will see challenges and proof attempts as they come through in the Last Attempted Proof section however you usually will not have a proof worth sending to the network due to the plot filter. You can additionally see the Total Size of Plots on the Farm view and it will tell you how much unique space is being farmed and statistically how long it should take - on average - to win a block. Also, your node needs to be synced for you to farm properly. In the GUI, check the Full Node page. On the cli, do chia show -s -c.
