NAMErrdtool tune - Modify some basic properties of a Round Robin Database PDF version.
SYNOPSISrrdtool tune filename [--heartbeat|-h ds-name:heartbeat] [--minimum|-i ds-name:min] [--maximum|-a ds-name:max] [--data-source-type|-d ds-name:DST] [--data-source-rename|-r old-name:new-name]
DESCRIPTIONThe tune option allows you to alter some of the basic configuration values stored in the header area of a Round Robin Database (RRD). All these tunable parameters together decide when data fed into an RRD is to be regarded as invalid. Invalid data is entered into the database as *UNKNOWN*. The main application of the tune function is to relax the validation rules on an RRD. This allows to fill a new RRD with data available in larger intervals than what you would normally want to permit.
EXAMPLE
Set the minimum required heartbeat for data sources 'in', 'out' and 'through' to 10000 seconds which is a little over one day in data.rrd. This would allow to feed old data from mrtg-2.0 right into rrdtool without generating *UNKNOWN* entries.
