I wouldn't discount SNMP so easily. A good SNMP agent will provide a
lot of useful information related to the system. Eg. see net-snmp
(opensource) or sysedge (Commercial).

You don't _ever_ have to write a MIB unless you're developing an SNMP
agent/layer for a custom application.

I've worked in environments (ISPs and Telecos) where we've had to
manange servers with numbers in the thousands. And generally the first
question we ask when a new device comes in is: "Is it SNMP enabled?"

Standard UNIX tools vmstat, traceroute, etc. are cool when you're
trying to debug a problem on a machine. Or when you have only a few
machines to maintain. But as soon as you hit about 30 - 40 machines,
your'e going to have problems.

SNMP (v1 and v2c) does, OTOH, have security drawbacks since the
packets pretty much "in the air". But with good host and network
security, you can work around them. SNMPv3 addresses most of the
security issues with the earlier versions.
