Questions on "howtograph.txt"

Hi Henrik,

I have been attempting to implement NCV graphing in hobbit, on version
4.1.2 and have run into a few problems/questions:

First, the question:  In the "slab" example, you custom test sends the
string "inode_cache" but in your NCV_slab entry in hobbitserver.cfg, you
have "inodecache:GAUGE".  How does this work???  

Second, the problem:  We have a custom test which checks printer toner
levels by going to the web page of the printer with lynx.  Our test,
called "toner" sends data in the format:

 lj102.toner

	black     : 67
	cyan      : 56
      magenta   : 78
      yellow    : 43

The data does go into the rrd, but does not appear in the "<last_ds>"
field, as in your slab example, but rather in the <value> field.  Our
graph shows up, but there is no data in it.

I'm fairly sure that the graphs will work once the <last_ds> field is
populated, but not sure where I made a mistake.  

Any thoughts?   


PS:  I have been a BB user since 1999, and moved our servers to hobbit
last Fall.  We absolutely love it.  Thanks Henrik!
