I'm just looking at the NCV_ stuff with the hobbit_rrd, and have some
questions about it (for my first time setup)
I was wondering how it would handle letters in the data stream, such as:
Total: 3520W
Reserved: 1223W
Used: 1223W
Remaining: 2297W
And also, spaces in the data, such as:
+5 Volts: +4.81 Volts
With this look like NCV_bladecentervolts="+5 Volts:GAUGE" ?
According to the help page (Hobbit menu -> Help -> Custom Graphs):
note that Hobbit strips off any part of the name that is not a letter
or a number;
I don't know how it would handle your "+5 Volts", but it does strip spaces
from everything before the colon to get the label, so
The CPU Temp: 45C
would result in an RRD variable called "TheCPUTemp".
There's an alternative way of doing this, which give you more control. Take
a look at the hobbitd_rrd manual page (Hobbit Menu -> Help -> Manual Pages
-> hobbitd_rrd. You can specify a script that processes the message to
generate the RRD definitions and the data values to store. This allows you
much more flexibility when extracting the data from the message.
