bbmrtg.pl help 🔗 link

Hello all

 I need to alarm on bandwidth thresholds so I have added bbmrtg.pl  
using this guide, http://www.pleiades.com/mrtgbb/.  Everything is 
working expect when bbmrtg.pl runs it reports  "In: bytes/sec (0.0%) 
Out: bytes/sec (0.0%)". When look at the graph produced by mrtg-rrd.cgi, 
it reports the correct usage which in case is "Current In: 68.8 Mb/s 
Current Out: 25Mb/s". It is as if bbmrgt.pl is not reading the rrd file.


Here is what my mrtg.cfg file looks like.

It's a timing problem - the rrd is being written after bbmrtg reads it,
so it's returning NaN.

I had to add a call to RRDs::last to make it work right:
   } elsif ($BACKEND eq 'RRD') {
        $last = RRDs::last($targetLog);
        my $first = $last - 300;
        my ($start, $step, $names, $data)
            = RRDs::fetch "-s $first","-e $last", $targetLog, 'AVERAGE';
        foreach my $dat (@$data) {
            if (defined($$dat[0])) {
               $i_now=($factor * $$dat[0]);
            }
            if (defined($$dat[1])) {
                $o_now=($factor * $$dat[1]);
            }
        }

        warn "last: $last, i_now: $i_now, o_now: $o_now\n" if $tron;

Sorry, I don't have the original code to do a proper diff...

Devmon works pretty well. We're having a bit of trouble with it concerning accurate estimation of load for some interfaces. I'm not the router guy, so I'm not sure of what's what.

Can I put devmon in the hobbitlaunch.cfg?

I've considered devmon in the past, but it doesn't meet my needs
because:
1.  template system isn't as flexible as mrtg's
2.  no support for snmp v3

I think there are a fair number of templates that show the opposite as well. 
Feel free to mention exactly what features are missing regarding templates.

Since there is no support in SNMP_Session for SNMPv3 ...

I am considering switching to net-snmp's SNMP module instead.

Of course, patches are welcome.

You neglected to note any advantages devmon has over mrtg though ....

Well, that's the problem.  You need a template for each type of gear in
devmon.  So, my Cat 3750-48PS-E would need a different template than a
Cat 3750G-24PS-E, and every combination of stack would need yet another
template. Instead, I can write a generic template in mrtg to cover
pretty much anything that runs IOS - it's just perl, so I can query mibs
and optionally include sections as I see fit.  Ditto for UPS - I have 4
major flavors of UPS, just one template.

Yes, I spliced in net_SNMP_Session as a "drop-in" replacement for
SNMP_Session in mrtg.  Took a couple of months, but I made it work.  I
had to design new syntax, and messed with much of the guts of mrtg.

Of course, patches are welcome.

Of course.  But that's a whole new program for me to wrap my head around
and do deep-dive coding.  Not enough spare grey cells or contiguous
seconds to do that.

I've not been able to use it, because of no support for SNMP v3.  devmon
was first released after I had fixed mrtg.

But the main advantage is easier integration with xymon, although
bbmrtg.pl works fine if you patch it.
