Command that lists all client connections (with ips)?

["Marc Roos" <M.Roos@xxxxxxxxxxxxxxxxx>]

What would be the best way to get an overview of all client connetions. 
Something similar to the output of rbd lock list 


  cluster:
            1 clients failing to respond to capability release
            1 MDSs report slow requests
