SPOTDELAY.CIFS.CLIENT(1)			      SPOTDELAY.CIFS.CLIENT(1)

NAME
       spotdelay.cifs.client  -	 A  Perl  script utility that reads through an
       CIFS Client output file, checking for delays and therefore  bottlenecks
       in its running.

SYNOPSIS
       spotdelay.cifs.client [-h] [-NNNN] <cifsclient log file>

DESCRIPTION
       This tool is part of the CIFS WTEC Support Tools suite.

       spotdelay.cifs.client  is a Perl script that runs through the user pro‐
       vided CIFS Client debug file looking at the time stamps	for  each  nfs
       line  in	 the trace.  It will issue a warning when the following condi‐
       tion holds:
	      Delays occur greater than a specified  time  between  sequential
	      lines in the trace.

       The  script  was designed to be short, but still readable, with the aim
       that it will be easy to cut&paste onto a  customer's	 system.   Be‐
       cause  of this, it takes only two command line arguments.  (See Options
       below)

       You will have to examine the  lines  that  spotdelay.cifs.client	 warns
       about  to see if there are actual bottlenecks, and what nfs request/re‐
       ply pairs are involved.

LIMITATIONS
       spotdelay.cifs.client will get confused by traces that  run  over  mid‐
       night,  since  it  assumes that the time shown is from the beginning of
       the day.

       spotdelay.cifs.client may also misreport delays near the end  of	 trun‐
       cated trace files.

OPTIONS
       -h     Print a summary of command line options.

       -NNNNN Sets  the	 maximum time (in milliseconds)between paired nfs com‐
	      mand and response lines above which  spotdelay.cifs.client  will
	      issue a warning.	For example to see if there are any lines with
	      1 second or more between them, set this to 1000.

OUTPUT
       It indicates the NFS command/response pairs that took longer than -NNNN
       milliseconds to complete.  The output is of the form:

       NFS Command [XXXXXXXX] took YYYYY ms to return

       Armed  with  this information, you can vi the log file itself to deter‐
       mine WHAT nfs command this was, and the events surrounding the event.

Dependencies
       spotdelay.cifs.client requires that the debug file input	 was  captured
       with the nfsTrace log level uncommented in the /etc/opt/cifsclient/cif‐
       sclient.cfg file.

       This script was developed and tested  under  perl(1)  version  5.005_02
       built  for  PA-RISC1.1 . While it may run under previous versions it is
       recommended that you install 5.005_02 or higher for best results.   You
       may  need  to  modify the first line to point to whatever location YOUR
       environment has perl installed.
