[rrd-users] Re: Just a basic question... one or multiple RRDs?

[Serge Maandag]

I'd always go for multiple rrd's, because adding or removing a ds from a
rrd is a pain in certain places.

So unless you are afraid that you'll have an amazing number of rrd files
or if you are definately sure that you will never have to alter the
number of ds's in the rrd, go for the 1 ds per rrd setup.

Serge.

I am going to be using RRD to store metrics on server health. For each 
5 minute interval, the following type of data is collected:
     CPU Utilization (%)
     Server Load
     Number of Processes
     Number of Threads
     Used Memory
     Free Memory
     Memory Cache Hit Rate (%)
     Filesystem A Space Used
     Filesystem A Space Free
     Filesystem B Space Used
     Filesystem B Space Free
     etc...

Can I create just a *single* RRD file to store all this different type 
of data? Or is it wiser to create separate RRDs... one for each 
group/type of data? My first instinct was to go the multiple RRDs 
route. But after thinking about it longer, I don't think I need to for 
any greate reason and it would be easier to just make one.

Thought I would run it by some people that experience ... this is my 
first time working with RRD.
