Hi RRD-users,<BR>
<BR>
I have RRD-files with 5 years of data captured every 5 minute.<BR>
1 DataSource per file that is defined as AVERAGE , and I have no consolidation of the data.<BR>
We want to be able to go back and look at the full resolution at any time.<BR>
We update around 800k RRD-files on a single server every 5 minutes.<BR>
<BR>
I want to export the data with some consolidation - say daily, weekly, monthly average numbers and want to be able to show the maximum and minimum I had during that consolidated time-slot. (not the total max/min of the final consolidated values).<BR>
<BR>
I can implement this externally using fetch - and then do the max/min calculations in each bucket, but I assume that this is the same thing that RRD-tool do internally whenever consolidated DS are updated.<BR>
How can I use these functions when exporting (and graphing) data.<BR>
When graphing data the consolidation-slots are calculated based on the data-points and available graph-resolution, so it would be nice to just say give me the max and min as an value-array just like in a CDEF.<BR>
<BR>
I have searched and searched, and made many unsuccessful tries with different VDEF, CDEF combinations - but no luck.<BR>
<BR>
Any ideas?<BR>
