[rrd-users] Re: adding datasources to existing RRDs using XML

Today you sent me mail regarding Re: [rrd-users] Re: adding datasources to...:

*> 	I, for one, have been bitten more than once (with Cricket, and
*> other things using RRD that I've tried/written), when I wanted to monitor
*> a new variable of an existing target.  I have to either trash all my old
*> data, and start with a new archive, with the new ds, or start a seperate
*> file.
*> 
*> 	Storing each ds in a seperate archive doesn't seem very effficient
*> either.  I haven't done any tests to back it up, but surely updating 1
*> file with 1,000 datasources would be quicker than opening 1,000 seperate
*> files.

sure ... it all depends on the stability of your environment .... if things
are very stable, sure you can use wide RRAs, but as a rule I would be
careful when doing so ... atleast untill someone contributes the all dancing
all sining rrd reconfiguration tool ...

cheers
