NAME

rrdtool resize - alters the size of an RRA.  

SYNOPSIS

rrdtool resize filename rra-num GROW|SHRINK rows  

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

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.
