[mrtg] Fwd: apollo_uptime.html

[Rodolfo J. Paiz]

Leandro,

When I create the target in mrtg.cfg using these parameters (the minimum it 
will accept):

### Interface 4 >> Get the uptime text for a separate file.
#
#Target[apollo_uptime]: 1:apollo-snmp at apollo.paiz.org:
#Suppress[apollo_uptime]: ymwd
#Title[apollo_uptime]:
#PageTop[apollo_uptime]:
#MaxBytes[apollo_uptime]: 10

then what I get is the complete webpage below:

Can you think of a way to eliminate this and keep just the text about the 
update time and uptime?

I have found that the code to generate this is here in /usr/bin/mrtg:

[rpaiz at apollo rpaiz]$ grep -C 15 "statistics were last updated" /usr/bin/mrtg
     print HTML <<"TEXT";
$$rcfg{'addhead'}{$router}
</HEAD>
$$rcfg{bodytag}{$router}
$$rcfg{'pagetop'}{$router}<BR>
<HR>
TEXT

     if (defined $$rcfg{'timezone'}{$router}){
     print HTML
       &$LOC("The statistics were last updated <B>$Today 
$$rcfg{'timezone'}{$router}</B>");
     } else {
     print HTML
       &$LOC("The statistics were last updated <B>$Today</B>");
     }
     if ($uptime && ! $$rcfg{options}{noinfo}{$router}) {
         print HTML
           ",<BR>\n".
         &$LOC("at which time $namestring had been up for <B>$uptime</B>.").
         "\n<!-- End Head -->";
     }

Is there a way I can add a piece of simple code which will open (and 
overwrite if it previously existed) $WORKDIR/apollo_uptime.html and just 
add the statistics/uptime text, then close it? I am afraid my perl 
abilities _were_ born yesterday, and I can barely understand pieces of this 
let alone modify it.
