You will probably want to approach this the same way that Xymon handles disk
sizes, with each disk getting stored in a separate RRD, and with a naming
convention that is compatible with hobbitgraph. It will take some fiddling.
There are two ways to "catch" this data on the Hobbit server and both are
documented. One is NCV, and the other is to write your own "data parser" as
an external script. I prefer the external data parser because it is more
flexible than NCV, but NCV is "compiled in" so therefore "supported".
The thing to look out for is this: the number of directories that you want
to track may be more than Hobbitgraph can handle. Depending on where you
are going with this you might need to look into using other RRD tools for
graphing so you can avoid the limits in Hobbitgraph (although it is pretty
good).
Are you going to update this every 5 minutes? If not, you will have some
other challenges to overcome if you try to leverage the Hobbit data
collection/graphing system.

If one of the directories is over the limit that has been defined, the line
is indicated with a "!" at the first character position. I will prepend the
output with "&green %date% %time%" or "&red %date% %time%" depending on
whether or not any "!" are found in the file to indicate the status of the
test. I will then replace the "!" with "&red" before storing the file into
%BBHOME%\logs\folders. I am considering having the "SUB-TOTAL: " stripped
from each line and having the header and footer/total lines stripped as well
before sending. This just covers how I will send the test to Xymon.
It sounds like you have some sample scripts that could help me in taking it
to the next level and by getting this reporting as data into RRD for
graphing. I am very interested in seeing these scripts so that I can work on
getting this working 100%.
Thanks so much.

Subject: Re: [hobbit] Folders RRD info
I am writing a new ext called "folders" that will provide a check to
see that folders do not exceed a certain size. For example, it will
check the folders that contain each user's personal network drive,
list them all with their sizes, and indicate any that are over the
limit. I have this much worked out and think that I have the red,
green, yellow parts of the script working properly.
However, it would be even better if I could store the sizes of these
folders within Hobbit/Xymon as data in RRD and have them graphed.
How do I send the data to Hobbit in a format that it will understand
as being RRD data and that will be tied to the "folders" test for this
host?
This sounds like a variable number of measurements (one per folder) with
a fixed number of parameters per measurement (one (size) or two
(size,max)). In that case you should use the '--extra-test' option (see
http://www.hswn.dk/hobbit/help/manpages/man8/hobbitd_rrd.8.html). You
probably also need a script to build the header of each graph. If you
like, I can send you sample scripts.
Within the body of the status message, you'll include the measured
values in NCV format, which might be embedded in HTML comment. Note that
you might need to change other lines in the status message in order to
avoid them to be interpreted as NCV. One way of doing so is to replace
each ":" by ":" and each "=" by "=". The script named in
"--extra-test" writes those values to RRDs. O, include a line in the
status message, before the measurements, stating the number of
measurements, that is include a line with "<!-- linecount=N -->" with a
suitable value for N.
Kind regards,
Wim Nelis.
