SPOTDELAY.CIFS.SERVER(1)			      SPOTDELAY.CIFS.SERVER(1)

NAME
       spotdelay.cifs.server - A Perl script utility that reads through a CIFS
       Server debug output file, checking for delays and therefore bottlenecks
       in its running.

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

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

       spotdelay.cifs.server  is a Perl script that runs through the user pro‐
       vided CIFS Server debug file looking at the time stamps for  each  line
       in  the	trace.	 It  will issue a warning when the following condition
       holds:
	      Delays occur greater than a specified time (NN seconds)  between
	      sequential lines in the trace.
	      Last  MAXCNT lines that take longer than MAXCNTDIFF time to com‐
	      plete.

       The script was designed to be short, but still readable, with  the  aim
       that  it	 will  be easy to cut and 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.server warns
       about to see if there are actual bottlenecks, and what specific SMB re‐
       quest/reply  pairs are involved.	 But I would not expect to see sequen‐
       tial lines in a trace file to take longer than 1 second.	 If  1	second
       intervals  is  not granular enough, spotdelay.cifs will work with trace
       files taken with microdebug=yes.

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

OPTIONS
       -h     Print a summary of command line options.

       -NN    Sets  the	 maximum  time	(in  seconds)between debug 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 1.

       MAXCNT

       MAXCNTDIFF
	      These 2 parameters work together, and can be set by editing  the
	      first  couple  of	 lines	in the script itself.  MAXCNT sets the
	      minimum number of sequential lines than need to be  seen	within
	      MAXCNTDIFF  time. So for example with MAXCNT at 10, and MAXCNTD‐
	      IFF at 1, spotdelay.cifs.server will issue a warning if it  sees
	      the  CIFS	 Server	 taking 1 second or more to produce 10 or less
	      lines. Be careful not to set MAXCNT too high, as the script  has
	      to remember the times from the previous MAXCNT lines.

OUTPUT
       spotdelay.cifs.server  prints  out any line where the current timestamp
       is NNNN milliseconds greater than the timestamp from the previous line.
       The output is of the form:

       NFS Command [XXXXXXXX] took YYYYY ms to return

       Armed with this information, you can view the log file itself to deter‐
       mine WHAT the events surrounding the delay were.

DEPENDENCIES
       spotdelay.cifs.client works best with a debug file input that was  cap‐
       tured with a log level = 10 in the /etc/opt/samba/smb.conf 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.
