[mrtg] [FORGED] Re: Minimum hardware

[thomaz portella]

Thanks,
I want to monitor approximately 100 network devices such routers and
switches.
If you guess I should use a bigger CPU, tell me what you think. Your
recommended configuration.
Because I haven't asked yet. And when ask, it will be difficult to change
or add more hardware.
Thanks,

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.
