rrdtool - Increase RRD step -


we have situation zennos collecting cycle 30s , have lots of data collected. need increase collection period 300s. problem zenoss stop rendering graphs that. need increase step 300s in rrd. there option , preserve old data , append new data?

i've checked rrdtool options , don't see option that.

thanks dubravko

you'll have dump data rrd xml file using rrdtool dump command. create new rrd new step parameters , import xml using rrdtool restore command.

it's not quite easy "resize" command be, keeps rrdtool lean , mean.

the downsize you'll lose 30s resolution earlier collections.

another option be, if wanted keep 30s information, change heartbeat (but keep step size @ 30s) when create new database (you'll still have export, recreate, , import).

hope gives enough direction. if not, let know.
