Re: {bb} Problems with displaying graphs with larrd-grapher.cgi

[pelmaillist <pelmaillists@lightbridge.com>]

I had some issues here also.

1)  don't use bb-1.9f, use bb-1.9h ->  notification was
broken in bb-1.9f 

2)  the larrd scripts were trying to get ENV vars out of bbdef.sh
while the newer version of big brother puts them in
bbdef-server.sh.  I added the following code to
larrd-grapher.cgi:

open(BBDEF,"<$ENV{'BBHOME'}/etc/bbdef.sh") or file_error("$ENV{'BBHOME'}/etc/bbdef.sh","$!");

while (<BBDEF>) {

        $cgibinurl_in=$_ if /^CGIBINURL=/;

        $bbweb_in=$_ if /^BBWEB=/ && $bbweb_in eq "" ;

        $fqdn_in=$_ if /^FQDN=/;

}

close BBDEF;

open(BBDEF,"<$ENV{'BBHOME'}/etc/bbdef-server.sh") or file_error("$ENV{'BBHOME'}/etc/bbdef-server.sh","$!");

while (<BBDEF>) {

        $cgibinurl_in=$_ if /^CGIBINURL=/;

        $bbweb_in=$_ if /^BBWEB=/ && $bbweb_in eq "" ;

        $fqdn_in=$_ if /^FQDN=/;

}

close BBDEF;

(undef,$ENV{'CGIBINURL'},undef) = split(/\"/,$cgibinurl_in);

env_error("CGIBINURL","$ENV{'BBHOME'}/etc/bbdef.sh") if $ENV{'CGIBINURL'} eq "";

(undef,$ENV{'BBWEB'},undef) = split(/\"/,$bbweb_in);

env_error("BBWEB","$ENV{'BBHOME'}/etc/bbdef.sh") if $ENV{'BBWEB'} eq "";

(undef,my $fqdn,undef) = split(/\"/,$fqdn_in);  # Extract FQDN Definition

my $bbskin_in="";

open(BBINC,"grep \"^BBSKIN=\" $ENV{'BBHOME'}/etc/bbinc-server.sh |") or file_error("$ENV{'BBHOME'}/etc/bbinc-server.sh","$!");

while (<BBINC>) {

        $bbskin_in=$_;

}

close BBINC;

3)  Also, I needed to make the following change in
larrd-grapher.cgi to fix an issue with the new version of RRD.  It
looks like the new version of RRD does not allow for ':' inside the
COMMENT fields, so I needed to replace the ':' inside the date string
with something else, I choose a '-'.  However, there may be more
issues like this related to LARRD and the new version of
RRD:

# must replace ':' in localtime with \\: do to RRD issue

my $date = localtime;

$date =~ s/:/-/g;

Hope this helps,
