I call rrdtool executable but I do group many datas as command line
parameters so I import multiple points within one rrdtool call, I also
call rrdtool from a Windows version of tcsh that support a much longer
command line parameter length so I can double the number of points I
can import within one rrdtool call.
I also made some kind of "differential import" that also optimize
importation of datas : all datas are originaly stored into a CSV that
is increasing each minute, CSV has a date/time column. Each time I
"import" this CSV into RRD I read last RRD data timestamp entry, then
I look for last entry line into CSV, then I start importation from
this last date and that's it. All done from a simple PHP script on
Windows (and this php script is started from tcsh windows version
