head2 RRDRowCount

This affects the creation of new rrd files. By default rrds are created to
hold about 1 days worth of high resolution data. (plus 1 week of 30 minute
data, 2 month of 2 hour data and 2 years of 1 day data).  Whith this Keyword
you can change the number of base interval entries configured for new rrds
as they get created. Note that you must take the interval time into account.

Example:

RRDRowCount[ezwf]: 1600
