Hi, I am new to Dtrace. I am trying to run nfsv3rwsnoop.d script found on nfsv3 provider wiki page. I received following error: # ./nfsv3rwsnoop.d dtrace: failed to compile script ./nfsv3rwsnoop.d: line 12: failed to grab process 3 Line 12 is "nfsv3:::op-read-start" To use nfsv3 provider, do I need to install some additional package? If so...
