NAME
rrdtool resize - alters the size of an RRA and creates new .rrd file
SYNOPSIS
rrdtoolresizefilenamerra-numGROW|SHRINKrows
DESCRIPTION
The resize function is used to modify the number of rows in
an RRA.
filename
the name of the RRD you want to alter.
rra-num
the RRA you want to alter. You can find the number using rrdtool info.
GROW
used if you want to add extra rows to an RRA. The extra rows will be inserted
as the rows that are oldest.
SHRINK
used if you want to remove rows from an RRA. The rows that will be removed
are the oldest rows.
rows
the number of rows you want to add or remove.
NOTES
The new .rrd file, with the modified RRAm, is written to the file
resize.rrd in the current directory. The original .rrd file is not
modified.
It is possible to abuse this tool and get strange results
by first removing some rows and then reinsert the same amount (effectively
clearing them to be Unknown). You may thus end up with unknown data in one
RRA while at the same timestamp this data is available in another RRA.
