That server looks a bit low in CPU, but it depends on what you’re monitoring (you have still not provided a number of actual metrics to monitor, though you indicate they are likely all to be SNMP which is much more efficient).


I would definitely suggest you use RRDCached in front of RRDTool; it greatly improves the disk IO and responsiveness.  If you do not use rrdcached, you may find that the machine fills its outbound disk queue and periodically freezes while trying to flush this.  However, it all depends on your disk speed and many other factors, so you will need to tune it as you go.
