Re: [Bubba-users] Changing interfaces

[Todd A. G. <sla...@aw...>]

Getting closer...

In the past I had only used the formulas to add interfaces that were
both taking data.

I just happen to have (back in march) a case like your where we moved a
connection from one interface to another.  When I setup the formula I
get the same results as you (calcs, but no graph).

Thinking I might have broken the formulas at some point I added one that
adds two interfaces that are currently being used.  That worked so that
tells me this is something I hadn't seen before.

BTW It is possible to enable 'debug' mode by adding &_debug=true at the
end of a particular CGI call.

One example would be to view the graph separatly (right-click and select
'view image' with mozilla).  You will then see the CGI call used to
generate the graph.  By adding &_debug=true you will see a dump of a ton
of data structures.  One of them looks like this:

$VAR3 = [
  '/tmp/bubba-cache/bubba-564d3f81.gif',
  '--title',
  'ITC DS/3 (Combined) - March, 2003',
  '--start',
  1046584800,
  '--end',
  1049262900,
  'DEF:in0=/usr/local/bubba/data/mn/routers/cisco/c7206-1/interfaces/serial2_0/200303.rrd:in:LAST',
  'DEF:out0=/usr/local/bubba/data/mn/routers/cisco/c7206-1/interfaces/serial2_0/200303.rrd:out:LAST',

  'CDEF:in_bits=0,in0,in1,+,+,8,*',
  'CDEF:out_bits=0,out0,out1,+,+,8,*',
  'DEF:dummy=/usr/local/bubba/data/mn/routers/cisco/c7206-1/interfaces/serial1_0/200303.rrd:out:LAST',
  'COMMENT:Interfaces:\\n',
  'COMMENT:  DS/3 to IDG\\n',
  'COMMENT:  DS/3 to ITC Deltacom\\n',
  'COMMENT:\\n',
  'COMMENT:                        Max                  95th Percentile\\n',
  'COMMENT:             ',
  'AREA:in_bits#00FF00:In',
  'GPRINT:in_bits:MAX:  %8.3lf %sb/s ',
  'HRULE:953978.166222225#000000:Current (in) ',
  'COMMENT:   953.978 kb/s',
  'COMMENT:\\n',
  'COMMENT:             ',
  'LINE1:out_bits#0000FF:Out',
  'GPRINT:out_bits:MAX: %8.3lf %sb/s ',
  'HRULE:3000000#FF0000:Contract     ',
  'COMMENT:     3.000 Mb/s'
];

This you might recognize (if you've worked with RRDTool directly) is the array of commands sent to RRDs::graph.

Somewhere in here lies the problem.

I think I've found one potential issue, but it may be with my data.  The start time listed is actually Sun Mar  2 00:00:00 2003 instead of Sat Mar  1 00:00:00 2003.  I haven't looked into this one yet, but I suspect Daylight Savings Time as being the culprit here.

Anyway back to the issue of no data in the graphs.

My thinking is that RRDGraph maybe getting annoyed about having two datasources one which doesn't have data at the end of the request time period, and another that doesn't have data at the beginning.

I'm going to setup some scripts to plug these args directly into RRDGraph and see what it gives me.

Thanks again for the help.
