nfsstat:tldr:fdced
The nfsstat
command is used to display statistics related to Network File System (NFS) operations on a Linux or Unix system. NFS is a protocol that allows file sharing across different machines on a network.
When you run the nfsstat
command, it provides various statistics and information about the NFS operations happening on your system, including:
-
Client statistics: It shows the number of bytes sent/received, RPC (Remote Procedure Call) retries, retransmissions, timeouts, and errors for each NFS client connected to the system.
-
Server statistics: It displays similar statistics as the client, but for the NFS server running on the system. This includes information on the number of read/write requests, cache hits, and errors.
-
Version-specific information: It provides details on NFS protocol versions supported by the system, such as NFSv2, NFSv3, and NFSv4.
-
Exported file systems: It lists the directories or file systems that are currently shared/exported via NFS on the system.
By analyzing the statistics output from nfsstat
, system administrators can gain insights into the performance, usage, and potential issues with NFS operations, helping them troubleshoot and optimize the NFS configuration and environment.
