Even with rrdcached, the I/O from many RRD files being updated often will hammer the I/O subsydtem of most hosts :)
We have a host with around 50k RRD data files and rrdcached running, most are updated every 5 mins, some every minute (Nagios + PNP) - with RAID 10 and 10k rpm disks the io wait on the system hangs out at about 15-20 pct, while load hangs around 1-2. I like rrd a lot but scaling it is hard. Max On 2/19/11, Rene Skjoldmose <rene.skjoldm...@gmail.com> wrote: > On 2011-02-18 22:03, Max Pierson wrote: >> Nothing at all :) My problem is with rrdtool.
