Is there a way to zero certain device data?

[ScottTFrazer]

We recently did a reorganization of our data center and had several servers move between switch ports. I'd like to discard the data for those switches so that we aren't fooled into thinking the historical data there is related to the new devices attached to them

Is there an easy way to do this? or am I going to have delete the affected devices and recreate them?

All data is stored in the rrd files -- delete those to purge all data. If you want to selectively purge data, then rrdtool dump the data to xml, edit it, and then reimport back to rrd.

I mostly agree with BSOD2600. My recommendation is indeed to delete the "old" rrd files. cacti will recreate them on the next polling interval, but they won't hold any historical data, as you requested

That was much easier than deleting the devices

Thanks!
