NFSv3 provider

[Simon Gao]

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, what is the package called?

The system runs Solaris 10 U7.

Thanks,

Simon
