hi!

this script should do it:
-----------------------------------------------------------
#!/usr/local/bin/perl
# sc_max <file> <ip-address>
# gives max value on snmpcollect files

        open(INF,qq|$ARGV[0]|);
        binmode(INF);
        $myip=sprintf('%02x%02x%02x%02x',split(/\./,$ARGV[1]));
        while(!eof(INF)) {
            read(INF,$line,20);
            ($s,$e,$ip,$data)=unpack('L L H8 d',$line);
            if($ip EQ $myip){
                 $maxdata=($data>$maxdata) ? $data : $maxdata;
            }
        }
        print "maximum value for $ARGV[1] in $ARGV[0] = $maxdata\n";

__END__
