::nfs_stat [-csb][-234][-anr] | $[count]

NFS statistics を表示します。以下の様な nfsstat コマンドと似たスイッチです。
::nfs_stat [-csb][-234][-anr]
::nfs_stat -c -> Client Statistics.
::nfs_stat -s -> Server Statistics.
::nfs_stat -b -> Callback Stats. (V4 only)
::nfs_stat -r -> RPC Statistics.
::nfs_stat -n -> NFS Statistics.
::nfs_stat -a -> ACL Statistics.
::nfs_stat -2 -> Version 2.
::nfs_stat -3 -> Version 3.
::nfs_stat -4 -> Version 4.
-csb のどちらも指定されていない場合は、3つ全てが想定されます。
-arn のどちらも指定されていない場合は、3つ全てが想定されます。
-234 のどちらも指定されていない場合は、3つ全てが想定されます。
-b は、-234 のフラグとは独立して動作します。
