John Herd asked:
Now I'm looking for a good network monitoring tool that would enable me to graph bandwidth use on switches, disk use on servers etc. I've got a mix of Windows servers and a pile of Cisco kit.
There's a profusion of network monitoring tools out there, so I'm after advice on what kind of setups folks in ALUG have experience of, and actually like, rather than a best of breed run down.
Off the top of my head, we do some of that with nagios, mrtg and add-ons for various control panels, but we don't have any Windows servers and I don't think we interface with Cisco kit (or at least if we do, it speaks good enough SNMP or similar that I forget it's Cisco).
Hope that helps,
