Have you ever had to answer the question “what is happening on my foundation right now?” As a foundation operator, this is a common question. The open-source “top” plugin for the cf CLI can be a valuable tool in helping track down issues.

The “top” plugin is unlike most cf plugins which typically run using various command-line arguments, output information to the terminal and then exit. Instead, when you run “cf top” on the command-line, it will initialize a text-based interface that will allow user interaction with the screen. It works much like
