Of course. :)
I expected the data in the rrd file to reflect directly
on the data that appears on the test page in Hobbit.
When the datatype is DERIVE, the number shown on the test
page in Hobbit - in this particular case flexlm and the
data shown is [ MATLAB : 2 ] - then this reflects directly
on <last_ds> field, the value is 2.
When the dataset is changed to GAUGE, the picture changes.
The value in the <last_ds> field, is always unknown.
The value field seems to be an integrated or averaged
function of the data shown in the test in Hobbit.
This is a feature of rrdtool. When the rrd file is created, it is built
with a specific start time and update interval. If your data is inserted
precisely on the update interval, it should be recorded as given. If the
update is *not* precisely on the update interval, it will be adjusted to fit
a curve based on previous values.
