z/OS NFS client debug trace capture

The z/OS NFS client records z/OS NFS client debug trace diagnostic information to the z/OS component trace buffer. z/OS NFS client error and informational messages are also recorded to the client log data sets. z/OS NFS Client log data set tracing is on by default and cannot be disabled. For additional information on z/OS NFS client component tracing, see Using z/OS component tracing.

The nfsstat UNIX shell command can be used to manage the error and informational message recording to the client log data sets. Superuser authority is required to issue this command. There is no console command control capability for the client log data sets.

In order to see all error and informational messages, the current buffers must be flushed to disk.

To flush the remaining data in the z/OS NFS client buffers to disk, enter:

/usr/lpp/NFS/nfsstat -d f

Other nfsstat command options are available to swap the current client log data set and clear the contents of the client log data sets:

To swap z/OS NFS client error and informational message recording to the next log data set, issue:

/usr/lpp/NFS/nfsstat -d s

To clear (reset) the client log data sets from the USS command line, issue:

/usr/lpp/NFS/nfsstat -d c
