Poll: Expectations In Terms Of Hardware Monitoring With A Dedicated Server

While dedicated server providers are quick to promote that they support the server hardware how proactive do you expect them to be in terms of identifying hardware problems?

When hardware goes bad a customer might see performance problems and report it, or perhaps notice hardware errors in the logs.

Or is it the host's job to be monitoring hardware components status? Would you consider such monitoring to be part of the basic service or an optional management extra?

I'm interested in your expectations with a typical dedicated server.
