The nfsstat command is used to display various NFS (Network File System) statistics in Unix-like operating systems. The -z option is used to display the statistics in a zero-based format.
When you run nfsstat -z, it will provide a summary of various NFS statistics, such as:
calls: Number of NFS procedure calls made.retrans: Number of retransmitted NFS procedure calls.authrefrsh: Number of times the client refreshed its authentication flavor.null: Number of null RPC requests.getattr: Number of GETATTR RPC requests (used to retrieve attributes of a file or directory).setattr: Number of SETATTR RPC requests (used to set attributes of a file or directory).lookup: Number of LOOKUP RPC requests (used to look up a file or directory by name).access: Number of ACCESS RPC requests (used to check file or directory access permissions).readlink: Number of READLINK RPC requests (used to read the target of a symbolic link).read: Number of READ RPC requests (used to read data from a file).write: Number of WRITE RPC requests (used to write data to a file).create: Number of CREATE RPC requests (used to create a new file or directory).mkdir: Number of MKDIR RPC requests (used to create a new directory).symlink: Number of SYMLINK RPC requests (used to create a new symbolic link).mknod: Number of MKNOD RPC requests (used to create a special file).remove: Number of REMOVE RPC requests (used to remove a file or directory).rmdir: Number of RMDIR RPC requests (used to remove a directory).rename: Number of RENAME RPC requests (used to rename a file or directory).link: Number of LINK RPC requests (used to create a hard link).readdir: Number of READDIR RPC requests (used to read a directory).readdirplus: Number of READDIRPLUS RPC requests (used to read a directory with attributes).fsstat: Number of FSSTAT RPC requests (used to retrieve file system statistics).fsinfo: Number of FSINFO RPC requests (used to retrieve file system information).pathconf: Number of PATHCONF RPC requests (used to retrieve path configuration).commit: Number of COMMIT RPC requests (used to commit cached data to stable storage).
The -z option simply changes the numbering of the statistics output to start from zero instead of one.
