This will sound like an MBA-esque question, but:
What is your organisation's _strategy_ in this area?
In large organisations, different departments will use different
monitoring tools, some licensed, some free, and the yield of these won't
be optimised (buzzword, drink!). Bob has laid out some very clear
requirements for his department, but are these the same requirements for
other departments? If there's an organisation-wide strategy then
scripts, tools, reports (hey, I like colours!) can be re-used - and
development effort that is invested in one area has greater impact.
Are there organisational monitoring strategies that people know of that
could be helpful here?
