FW: [hobbit] FW: RRD data points - need help with graph distortion

[Wood, Mike]

Hi All,

I've used rrdtool resize to change the datapoints / rrd to 5760, but now some, but not all of my graphs only go back 7 weeks.  For example, my 60 day, 90 day, and 1 year graphs all only go back 7 weeks, but my 2 year graph goes back to when I installed / configured hobbit originally - June / July of this year.  Any idea what gives?
-
BTW - I have modified hobbitgraph.c to force it to show more than the 4 default graphs.

Thanks in advance!

I have a perl script to update all the rrd files:

- it uses rrdtool resize <rrd file> GROW to add extra datapoints so the rrd
has 5760 data points / rra (per default it has 756 data points)

- it adds also MAX and MIN rra's, this is more tricky because I export the rrd
to xml, change the xml info and revert back to an rrd file.

Unfortunatly, I can not share this script.  But with
use RRDs ;
use File::Find ();
you can get info about the file and find them ;)
