NAME    [Toc]    [Back]

       nfslogsum - Summarize nfswatch log file

SYNOPSIS    [Toc]    [Back]

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

OPTIONS    [Toc]    [Back]

       Directs  nfslogsum to read only the first n entries in the
       log file. This is useful  for  summarizing  log  files  in
       cumulative  chunks.  Produces a verbose summary of the log

DESCRIPTION    [Toc]    [Back]

       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  onepage
  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: Does
       nothing.  This  procedure  is  provided  to  allow  server
       response  testing  and  timing.   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.   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).   Gets  the
       file system root. This procedure is obsolete, and has been
       replaced by a MOUNT protocol procedure.  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.  Reads
       from the symbolic link. This  procedure  is  used  by  the
       readlink  system  call and by the kernel.  Reads data from
       the file. This procedure is used  by  the  read(2)  system
       call.  Writes to the cache. Unused in the current NFS protocol
 revision.  Writes data to a file. This procedure  is
       used  by  the  write(2) system call.  Creates a file. This
       procedure is used  by  the  creat(2)  and  open(2)  system
       calls.   Removes  a  file.  This  procedure is used by the
       unlink(2) system call.  Renames a file. This procedure  is
       used  by  the  rename  system call.  Creates a link to the
       file. This procedure is used by the link(2)  system  call.
       Creates  a  symbolic  link  to the file. This procedure is
       used by the symlink(2) system call.  Creates a  directory.
       This  procedure  is  used  by  the  mkdir(2)  system call.
       Removes  a  directory.  This  procedure  is  used  by  the
       rmdir(2)  system  call.   Reads  entries from a directory.
       Generally only one READDIR call is needed  per  directory,
       since  a variable number of entries can be returned.  Gets
       file system attributes (transfer size, block size,  blocks
       in  use,  blocks  free).  This  procedure  is  used by the
       statfs(2) system call.

RESTRICTIONS    [Toc]    [Back]

       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.
