What command displays NFC kernel statistics? (Specify ONLY the command without any path or parameters.)
正解：
nfsstat
Explanation:
The command that displays NFS kernel statistics is nfsstat. This command can be used to show information about the number and type of NFS and RPC calls made by the NFS client or server. It can also be used to reset the statistics to zero, or to display information about mounted NFS file systems. The nfsstat command is part of the nfs-utils package and can be installed on most Linux distributions. For more information about the nfsstat command, you can refer to the following resources:
1: A Microsoft Learn article that explains the syntax and usage of the nfsstat command on Windows Server.
2: A Bing search result page that shows various links and snippets related to the nfsstat command.
3: A Red Hat article that demonstrates how to use the nfsstat and nfsiostat commands to troubleshoot NFS performance issues on Linux.
