Steve,
  The documentation on genweb-filter.cgi is lacking for me as 
well.  I turned to the source.  Genweb-filter will really only
do the job of creating a suitable URL for genweb.cgi.  If you can
craft a suitable parameter list by hand, you will have a mechanism
to create a coarse 'view' of SNIPs.  The filepat parameter refers 
to the monitor (nsmon,hostmon, xxmon).  I believe that you need 
the namepat parameter.

Example:
Info view:	http://snipshost/genweb-cgi?view=Info
Info view of all BGP sessions
		http://snipshost/genweb-cgi?view=Info&filepat=bgpmon
Info view of all hosts named mis-<hostname> or <xxx>-server
		http://snipshost/genweb-cgi?view=Info&namepat=mis|server

I would edit the cgi where a text field is created named 'filepat'
around
line 110, changing the 'file pattern' to 'monitor name pattern'.  I
would 
also add in the device name selector as well above or below.

  print "<p>device name pattern? \n",
    $query->textfield(-name=>'namepat',
                      -default=>'',
                      -size=>15,
                      -maxlength=>20
                     ), "\n";

  print "<p>monitor name pattern? \n",
    $query->textfield(-name=>'filepat',
                      -default=>'',
                      -size=>15,
                      -maxlength=>20
                     ), "\n";

Now for anyone else in the list, I would like to turn this around and
ask my own question.  How does one create a menu that lists a view
that requires multiple selectors.. e.g., select both a monitor and
a device name spec?
	
my %watchpat = (
        'namepat=otr|qtr|gtr|gigapop' => 'Northern Lights GigaPOP',
        'filepat=nsmon|radiusmon' => 'Nameservice/Authentication',
        'namepat=vpn' => 'VPN Service',
        'namepat=ntc-ww|ATM\.' => 'WireWall Aggregators',
        'filepat=hostmon' => 'Generic Host Monitoring'
        );
my @watchfields = keys %watchpat;

in print_form():
  print "<p>Canned filters \n",
    $query->popup_menu(
                        -name=>'genpat',
                        -values=> \ at watchfields ,
                        -labels=>\%watchpat,
			-size=>25,
                        -default=>''
                        ),
        "\n";

I expect that I need to modify make_url() but don't know how
to print the selector group properly.  I suspect that a line
that looks like &genpat=&namepat=this|that|theotherthing would
work.  Any suggestions for me?
