I was curious how to view sessions on a Linux box I had at my desk. Similar to the session table on an Aruba controller (show loginsessions). Here are some ways you can list active SSH sessions; some commands return more output than others. This applies to most modern Linux boxes or say a WLAN Pi.
All examples below are using 2 MobaXterm user sessions from a Windows machine to a Linux 4.14.42-sunxi64 aarch64 (NanoPi NEO2).
