Hi Michael, I am not aware of such an extension, but changes might actually not be all that difficult ...
I guess turning the step parameter from seconds into milli seconds would be all that is required ... there would still be enough head-room above unfortunately such an extension would require a change in rrdtool data format which makes it difficult to fold this back into mainline ... but for your research the patch should be fairly simple ... cheers tobi Today [email protected] wrote: > Hello, > > I am researching rrd-[developers|users] archives whether someone have > done the extension of the RRD tool for milliseconds/sub-second stepping > (e.g., --step 500ms) in the past? > > To date I found some mail threads with references to the subject but > without an explicit success mark. > > Using this sub-second extension, I want to research mechanical gearboxes > installed on remote sites in the field collecting the analogue data from > gearbox' sensors in an RRA over 1 year via site local network.
