NCV, devmon and rrd and graphing problem

[Mike Dingeldey]

I am currently running hobbit 4.2.0/all-in-one patch on a Compaq DL360 using FC6.

At the present time, I am attempting to use devmon to feed data to hobbit and create a graph
form the resulting information. The only test I am running is the if_load test; I am running it
against a Cisco 2600 using the base 2600 template. I am running devmon 0.2.2

At the current time, NCV creates and updates the if_load.rrd file. The if_load column appears on
the hobbit page, and the if_load detail displays a table with the correct flow rates on the interfaces.
However, I am unable to create any graphs of the data.

At this point, I am assuming the devmon is feeding the correct data to ncv. My test router has five
interfaces (loopback, one etherent, a serial and two frame-relay subinterfaces) so how do I verify
that the resulting if_load.rrd file is in fact correct? 

>From what I have checked, everything looks like it should work. I'd like to go farther with verification on 
the rrd side, but the if_load.rrd file structure (and the tableborder) has me scratching my head.
Could the bottom line be that I didn't define the data type for NCV correctly? The reason I ask is that
the only time anything did not complain was when I defined the data type as a counter. I used
"*:Counter" because I did not know what the names were going to be. Also, could the if_load
file names be part of the problem?

Any help or insight would be greatly appreciated!
TIA!


I currently have the following:

TEST2RRD = "blah,blah,blah.....,if_load=ncv)
NCV_if_load="*:Counter"
GRAPH="blah,blah,blah,...,if_load)
