I also remember seeing an add-on which allowed you to dump your data points into a MySQL database.
This would allow you to maintain max granularity for as long as your disk space held out.
If I recall, there was no modification or recompilation of the code required. (But don't quote me on that)
Search the archive, and see what comes up.
Cheers

Subject: [hobbit] FW: RRD data points - need help with graph
distortion
Hi All,
I asked this question last week, but maybe I wasn't clear enough as to
what I was asking... - Management wants to avoid graph distortion on
my 60 day CPU Util graph if possible. I think that more datapoints
would address the problem. The first graph looks good (30 day graph).
The 2nd one distorts what is really going on (60 day graph - same
server). Is there any way to make the 2nd graph more granular?
Thanks for looking! -
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 ;)
