nfslogsum(8)
NAME
  nfslogsum - Summarize nfswatch log file

SYNOPSIS
  /usr/sbin/nfslogsum [-n] [-v] [logfile]

OPTIONS
  -n  Directs nfslogsum to read only the first n entries in the log file.
      This is useful for summarizing log files in cumulative chunks.

  -v  Produces a verbose summary of the log file.

DESCRIPTION
  The nfslogsum command summarizes log files produced by the nfswatch
  program. By default the log file nfswatch.log is summarized; an alternate
  log file can be specified on the command line.

  Each nfswatch log file may contain one or more log sessions, each indicated
  by a header which is printed when logging is turned on. For each log
  session, nfslogsum tallies up the interval packet totals and prints out a
  one-page summary of the log session. Total packets and percentages are
  tabulated for each category and displayed.

  In addition to the summary information printed as described above, a
  summary of how many calls to each NFS procedure were made on each file
  system and individual file will be printed. This summary information is
  divided into three sections of six columns each. The columns are headed by
  the names of the following NFS procedures:

  NULLPROC
      Does nothing. This procedure is provided to allow server response
      testing and timing.

  GETATTR
      Gets the file attributes (type, mode, number of links, owner's uid,
      owner's gid, size, access, modification and change times, and others).
      This procedure is used by the stat(2) system call, as well as several
      others.

  SETATTR
      Sets the file attributes	(mode, owner's uid, owner's gid, size in
      bytes, access and modification times). This procedure is used by system
      calls such as chmod(2), chown(2), and truncate(2).

  GETROOT
      Gets the file system root. This procedure is obsolete, and has been
      replaced by a MOUNT protocol procedure.

  LOOKUP
      Looks up the file name. This procedure is used to obtain an initial
      file handle for use in current and future requests on that file, and is
      used by many different system calls.

  READLINK
      Reads from the symbolic link. This procedure is used by the readlink
      system call and by the kernel.

  READ
      Reads data from the file. This procedure is used by the read(2) system
      call.

  WCACHE
      Writes to the cache. Unused in the current NFS protocol revision.

  WRITE
      Writes data to a file. This procedure is used by the write(2) system
      call.

  CREATE
      Creates a file. This procedure is used by the creat(2) and open(2)
      system calls.

  REMOVE
      Removes a file. This procedure is used by the unlink(2) system call.

  RENAME
      Renames a file. This procedure is used by the rename system call.

  LINK
      Creates a link to the file. This procedure is used by the link(2)
      system call.

  SYMLINK
      Creates a symbolic link to the file. This procedure is used by the
      symlink(2) system call.

  MKDIR
      Creates a directory. This procedure is used by the mkdir(2) system
      call.

  RMDIR
      Removes a directory. This procedure is used by the rmdir(2) system
      call.

  READDIR
      Reads entries from a directory. Generally only one READDIR call is
      needed per directory, since a variable number of entries can be
      returned.

  STATFS
      Gets file system attributes (transfer size, block size, blocks in use,
      blocks free). This procedure is used by the statfs(2) system call.

RESTRICTIONS
  The nfslogsum utility is sensitive to the format of the log file produced
  by nfswatch. Do not edit or change the log file before using it as input to
  nfslogsum.
