[mrtg] MRTG not graphing results?

[John Oliver]

Machine is Red Hat 7.2  MRTG 2.9.17

Using Apache stuff from http://www.linux-sottises.net/en_mrtg.php

Config file:

WorkDir: /home/www/sdsitehosting.com/mrtg/
Interval: 10
Target[apache-hits]: `/usr/local/mrtg-2/bin/webstat.pl hits`
Options[apache-hits]: growright, nopercent
MaxBytes[apache-hits]: 10000
Title[apache-hits]: sdsitehosting.net Apache hits
PageTop[apache-hits]: <H1>sdsitehosting.net Apache hits</H1>
YLegend[apache-hits]: Hits/10 min.
ShortLegend[apache-hits]: hits/10 min
Colours[apache-hits]: YELLOW#F9C000,RED#F90000,DARK
GREEN#006600,VIOLET#FF00FF
Legend1[apache-hits]:  Hits
LegendI[apache-hits]:  hits:
LegendO[apache-hits]:

[joliver at ns joliver]$ cat /usr/local/mrtg-2/bin/webstat.pl
#!/usr/bin/perl

@res = `lynx -dump http://localhost:80/server-status`;

foreach $res (@res) {
    if ($res =~ /Server uptime: (.*)$/) { $up = $1; last } else { next }
    if ($res =~ /Server at/) { $server = $res; last } else { next }
}

@res = `lynx -dump http://localhost:80/server-status?auto`;

foreach $res (@res) {
    if ($res =~ /Total Accesses: (\d+)/) { $d1 = $1; next }
    if ($res =~ /Total kBytes: (\d+)/) { $d2 = $1 * 1024; next }
}

$d1 = int($d1);
$d2 = int($d2);

if ($ARGV[0] eq "hits") {
    print "$d1\n";
    print "$d1\n";
} elsif ($ARGV[0] eq "bytes") {
    print "$d2\n";
    print "$d2\n";
}

print "$up\n";
print "$server";


/usr/local/mrtg-2/bin/webstat.pl does return valid-looking results:

[joliver at ns joliver]$ /usr/local/mrtg-2/bin/webstat.pl hits
1514
1514
3 hours 35 minutes 8 seconds

MRTG does seem to read those results:

[joliver at ns joliver]$ head -10
/home/www/sdsitehosting.com/mrtg/apache-hits.log
1071651614 1433 1433
1071651614 0 0 0 0
1071651005 0 0 0 0
1071651000 0 0 2 2
1071650700 0 0 2 2
1071650400 0 0 0 0
1071650100 0 0 0 0
1071649800 0 0 1 1
1071649500 0 0 0 0
1071649200 0 0 0 0

After it runs:

[joliver at ns joliver]$ head -10
/home/www/sdsitehosting.com/mrtg/apache-hits.log
1071652206 1518 1518
1071652206 0 0 0 0
1071651614 0 0 0 0
1071651600 0 0 0 0
1071651300 0 0 0 0
1071651000 0 0 2 2
1071650700 0 0 2 2
1071650400 0 0 0 0
1071650100 0 0 0 0
1071649800 0 0 1 1


But nothing ever gets graphed.
