Here's something that Paul Blackman sent me that may be useful:

-------------------
I created this script to do a few things that smbstatus doesn't at the
moment.  Perhaps you might want to include these.  Sorry I haven't
added things at source level, script was quick&easy.

*******
#!/bin/csh
if ($1 == "-p") then
  smbstatus -p |sort -u
else if ($1 == "-c") then
  echo There are `smbstatus -p |sort -u |grep -n -v z |grep -c :` unique
smbd processes running.
 else if ($1 == "-l") then
  echo `date '+ %d/%m/%y %H:%M:%S'` `smbstatus -p |sort -u |grep -n -v z
|grep -c :` >>$2
else
  smbstatus |sort +3 -4 -u
endif
******

The '-p' option was just to show unique PIDs.

The more important ones are the '-c' and '-l' options '-c' just counts
the number of unique smbd's, While '-l' logs this count with date and
time to a log file specified on the command line.  I'm using '-l' at
the moment with cron to give me an idea of usage/max connections etc.
I was also thinking of doing a log for individual/specified services.

The default (last) option was to show unique PIDs with user names.
Unfortunately this still lists all file locks etc.  This would be
better with a 'no locked files' option from smbstatus (or is there one
that I didn't see)

Cheers,
