I have cricket setup and gathering quite a few stats from servers and switches. I have started out with basic stats but now wish to collect more. It appears that in order to have the new stats go into the same rrd file I need to dump the rrd, modify the xml file and then load the new config for the rrd.
Is there any other way to do this ? How do people do this as cricket usage grows ? Do you create new targets so you don't lose the history or is there an easy way to create a new rrd file and load the existing data into it ?
