[hobbit] NCV, devmon and rrd and graphing problem

Buchan,
  Thanks for the information. Also, thanks for clarifying my questions - unfortunately I thought
  I could pull the data in via NCV based upon various other discussion threads. 
   
  I could start by monitoring my switches, but I get more questions now in regards to circuit
  utilization than anything else. Liek they say, a picture is worth 1000 words. 
   
  Oh well - back to the drawing board!  :)
  Thanks for the help.

AFAIK, this isn't possible yet. It may be better to discuss this issue on the 
devmon list. E.g., there has been discussion of an rrd collector module for 
Hobbit that may ship with the next release (which will avoid the whole NCV 
issue.

I don't currently have SNMP access to our routers, but I am monitoring our 
Cisco switches with devmon 0.2.2.

Right, but AFAIK, devmon doesn't currently send any test data to Hobbit in a 
format the ncv collector can use.

But, the data sent by devmon is in HTML, and not in the form:
name [:=] value
(except for the HTML tags ...)

You can't just use NCV on an arbitrary test, the data format has to be 
compatible with NCV (which devmon isn't), or NCV will correct the wrong data 
(eg the value of the number following "table border =").

The rest of your problems with NCV are irrelevant (unless you need NCV for 
some other test).

Regards,
Buchan
