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 ;)
