Re: [cobalt-users] RE: RAQ3 128MB - load average: 64.62, 73.63, 42.86

["Tong Narak" <tong@xxxxxxxx>]

Dear Tony Cook,

Thank you very much. Below is the code of go.cgi
These script have to run when user click on link in my webboard.
I have 10,000 hits per day. Does RAQ3 can't handle it ?


#!/usr/bin/perl

use CGI;
$q = new CGI;

&CheckDetail;


############################### ReLocation #################################

print "Location: $URL \n\n";


############################### Count Hits #################################

if ( ! -e "dat/${DATE}.dat" || $URL eq "" )
{
	exit;
}


open(DATA,"+<dat/${DATE}.dat") or die;
flock(DATA,2);
@data = <DATA>;
seek(DATA,0,0);
foreach my $item (@data)
{ 
	$item =~ s/\r//;
	$item =~ s/\n//;
	next if ($item eq "");
	@items = split( /<f>/ , $item ); 
	$items[1]++ if ($items[6] eq $URL);
	print DATA join("<f>", @items[0..8], "\n");   
}
truncate(DATA, tell(DATA));
close(DATA);



################################ Save log ##################################

#if ( open(LOG,'>>dat/go.dat') )
#{
#	print LOG "$DATE<f>$URL<f>$IP<f>$ENV{HTTP_REFERER}<f>\n";
#}


############################ Check Submission ##############################

sub CheckDetail
{
	$DATE  =  substr( $q->param('DATE') , 0 , 10 );
	$DATE  =~ s/<//g;
	$DATE  =~ s/>//g;

	$URL   =  substr( $q->param('URL')  , 0 , 80 );
	$URL   =~ s/<//g;
	$URL   =~ s/>//g;

	$IP    =  $ENV{REMOTE_ADDR};
}

exit;

No, that won't be the problem in this case, load problems are a CPU issue,
too much load on the CPU.  A load average of 42.86 over 15 minutes means
that for the past 15 minutes, you've had, on average, 42 processes waiting
to be served by the CPU. Load average should be below 1 for over 15 minutes.
It might spike in the short term but should always be below 1 for 15 minute
averages.

The problem seems to be that "go.cgi" script that the support user is
running.  Delete that script fast and tell the user to write something less
taxing on the CPU.  Maybe it's doing too many file opens, or infinite loops
or other silly stuff.  Probably a perl script too.

If you want my advice - disable cgi scripts on your raq and tell users to go
learn PHP.  It's better for simple scripts anyway.

Hope that helps.
