what is the output structures from rrdtool xport using RRDs. There seems to be
number of rows
and two references to arrays. One array has nested references leading
to row data.
What is the other array for? Also does xport average if the requested
CDP's are less than what the selected resolution. For example if
requesting 10 CDP's (using M option) for last 30m and the RRA selected
has a resolution of 5 sec, and a CF of AVG, then does xport perform
considation to find 10 values and if yes what is the algorithm and how
deos it select the 10 timepoints.
Also my experience is that this is the only way you can extract a
of DS's from RRD's. PRINT function in graphing doesn't let you touch
DS and CDEF. Is that a correct understanding?
