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.

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 ;)
