If you want to store more data, use resize. It does create a new rrdfile so that you can verify the result before you replace the original file. I suggest you use resize once and check that you got it right, and then do: 1: wait until an update is performed 2: rrdtool resize 3: copy the new file over the original file all without any hesitation. This way you should not loose any updates in the process. >>From what I have seen, the only way to do this is to delete our files and > start again which would mean that we would lose a whole years worth of > information. > > Whilst I understand that the amount of data stored on a monthly basis is > not > going to be as precise as that stored on a daily basis, I would like to > avoid losing this information. > > Is there any way to copy over the RRD data to a new file and to "fill in > the > gaps" for want of a better phrase? There are ways, but do you still need them? _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
