Will it work?
open (TEST, "C:\\sample.log");
my $valcount=0;
my $missvalue = 1;
while (<TEST>)
{
if(/value : (\d+)/)
{
$val = $1;
$val = $val - 1 if($val> 0);
if ($valcount != $val)
{
$valc = $valcount + 1 ;
print "\nMissing $valc to ". $val;
}
$valcount=$1;
}
$valcount=0 if($valcount==255);
}
Let me know if it does not suit
Thankyou
VENU

Subject: Re: Missing sequence finder for logfiles
Sorry!
This is what I´ve come up with so far:
my $nr=0;
my @missing;
open (FILE, "<logfile.txt") or die "Can't open $file: $!\n";
print "Started\n\n";
while (<FILE>) {
($firstbit, $value)=split /:/,$_;
$value=trim ($value);
if ($firstbit eq "- value ") {
if ($nr==256) {
$nr=0;
print "New Sequence Started\n";
}
if ("$value" ne "$nr") {
print"read $value expected $nr\n";
push (@missing,"$nr-$value\n");
$nr = $value;
}
$nr++;
}
}
print "missing ranges\n\n";
print for (@missing);
close FILE;
sub trim {
my @out= @_;
for (@out) {
s/^\s+//;
s/\s+$//;
}
return wantarray ? @out : $out[0];
}
It would be nice though, to be able to give the log filename as a parameter
to the perlscript. If the filename differs from time to time, it would be
nice if I could avoid having the filename within the script.
