Problems with graphing

[Adam Goryachev]

I am trying to create some new hobbit graphs, and am having some 
challenges, hoping someone can point out my silly mistakes.

~hobbit/server/bin/bb 127.0.0.1 "hobbitdlog softswitch.domain.net.au.astnet"
softswitch.domain.net.au|astnet|green||1154932188|1154948263|1154950063|0|0|202.92.33.172|-1|||Y
green Mon Aug  7 20:57:35 EST 2006
Current Asterisk status:

&green Channels: 16
SIP: 4
IAX2: 4
Zap: 8
&green OK: Got 1 reply


I've set the following in hobbitserver.cfg:
NCV_astnet="greenChannels:GAUGE,IAX2:GAUGE,Zap:GAUGE,SIP:GAUGE"
TEST2RRD="cpu=la,etc,etc,astnet=ncv"
GRAPHS="la,disk,etc,etc,astnet,ncv"

In hobbitgraph.cfg I added:
[astnet]
        TITLE Asterisk Channels Information
        YAXIS: Channels
        DEF:Channels=astnet.rrd:greenChannels:AVERAGE
        DEF:ZAP=astnet.rrd:Zap:AVERAGE
        DEF:IAX2=astnet.rrd:IAX2:AVERAGE
        LINE2:Channels#00CCCC:Total Channels
        LINE2:ZAP#FF0000:ZAP Channels

My rrd files seem to be working, in that they do collect some data:
rrdtool dump astnet.rrd

Which seems to indicate that the data is actually making it's way into 
the RRD file, even though at the top of the file, it doesn't show valid 
data (last_ds).

So, apart from the rrd file not looking quite right, I don't get a 
actual graph on the status (or trends) column. I get a link, but no 
actual graph.

If anybody has some hints or suggestions, they would be greatly 
appreciated. I am running version from hobbit_4.1.2p2-2_i386.deb which I 
downloaded today.

Any suggestions/help greatly appreciated

Adam
