Another newbie needs help w/ custom graphs

I've been working with Hobbit for all of a couple of weeks now, although
I have some limited exposure to Big Brother in a previous life...

 
In order to learn the tool better, I wrote a simple custom monitor that
watches Heap usage in an application server.  This seems to be
collecting data fine, but now I want to figure out how to graph this
information in an rrd graph.

 
Here's where I stand.

 
- I have a column called "weblogic" in Hobbit.

- When you click on that column for a given host, you see a field called
"used_heap"

- I edited hobbitserver.cfg and added a piece at the end of the TEST2RRD
line:   weblogic=ncv

- I also added a line to the same file:    NCV_weblogic="usedheap:Gauge"

- I I'm generating a file called weblogic.rrd in ../data/rrd/<HOSTNAME>

 
But, when I go to the weblogic column, at the bottom of the page there
is a space where the graph should be that says "hobbit graph
ncv:weblogic"  No graph.

 
I THINK everything is ok up to this point, but then comes the
hobbitgraph.cfg file, and I have to be honest, I really don't understand
this file at all and haven't come across a good explanation yet, so I'm
open to someone telling me to go read some website before I post, if
it's glaringly obvious. I used some other files and the examples I found
online to come up with this...

 
[weblogic]

        TITLE Heap Usage

        YAXIS Bytes

        DEF:heap=weblogic.rdd:usedheap:AVERAGE

        LINE2:heap#00CCCC:Heap Used

        COMMENT:\n

        GPRINT:heap:LAST:Heap Used \: %5.1lf%s (cur)

        GPRINT:heap:MAX: \: %5.11f%s (max)

        GPRINT:heap:MIN: \: %5.11f%s (min)

        GPRINT:heap:AVERAGE: \: %5.11f%s (avg)\n

 
I could use some help getting this graph going, and even explaining the
entries in the hobbitgraph.cfg file if anyone has the patience to help
walk me through this.

Brian,

Remember to bounce Hobbit after the change as it only processes the file at startup time.

Hi Rich,

I added that and bounced Hobbit, but it didn't seem to help.  
Any other thoughts?
