[rrd-users] Re: Machine spec'd..

[Tobias Oetiker]

Yesterday you sent me mail regarding [rrd-users] Machine spec'd..:

*> I've previously posted that I'm currently tracking 17,000 data points per
*> minute (1,700.RRD's with 10 data points each, with 7 RRA's each).  We were
*> killing a poor Sun e250 with dual CPU and 6 drive raid.  In this
*> configuration that poor box was *barely* able to keep up, and when things
*> were broken for mroe than a few minutes, the effort for it to catch up was
*> pretty significant.
*> 
*> My new hardware is finally online, and screams.  e450, 4*400 mhz cpu, 4
*> gig ram, and 20 drives total (2 raids of 8 for  RRD databases, 4 drives
*> for general purpose).  This new system has zero problem keeping up with
*> realtime updates now (old system lagged by up to a minute).  We're now
*> tracking 18500 values and doing a damned fast job of it.  I'm *guessing*
*> that we can comfortably go up to 35000 values per minute before having to
*> get another box.
This sounds impressive ... pwoa ...

OTOH ...

you might also want to pay some money to a optimisation guru to add memory
mapped IO or something like this to rrdtool :-)
