Hello Guys,
I have a server with FreeNAS-9.10.2-U1, so I have tried debugging the NFS clients connections with the following command:

Code:
dtrace -n 'tcp:::accept-established { @[args[3]->tcps_raddr] = count(); }'
dtrace: invalid probe specifier tcp:::accept-established { @[args[3]->tcps_raddr] = count(); }: "/usr/lib/dtrace/io.d", line 43: operator -> cannot be applied to a forward declaration: no struct devstat definition is available



So, I saw the Kernel "/usr/lib/dtrace/io.d" is not available.
Any chance to add in the kernel this library?, or I must be wait it in some next version or ask for it in the forum?

Thank you.
