This utility is no longer maintained thus was dropped. you have a new set of IB tools coming with ibutils2 package which can show you relevant information.
Thank you for the information. I thought it may have been superseded by the ibutils2 package. Since collectl parses the command for output, I guess I was hoping to find an example of the output so I knew more specifically what it was looking for. I'll dive into the ibutils2 package and see if it really matters. Perhaps it's more of a collectl question at this point. Again, thank you for the response.
