Among virtual hosting providers, there is usually an amount of storage and bandwidth specified in the service description (example: 50 GB storage, 1 TB bandwidth/month) but no such thing for CPU usage. However, usually a clause in the agreement says something about using resources excessively.

  • How is this measured?
  • What is the measurement units?
  • What is being measured?
  • Is this a CPU usage percentage?
  • Does the peak count or the average (over a period)?
  • Excessive relative to what?
  • Since no measure is specified in the agreement, what can be done to avoid being squeezed into more expensive plans?

You need to either specify a single host here, or ask whoever you're thinking about directly.

This isn't done the same way by all hosts, but as far as a couple of the later points, some disclose details within their technical information for how this is calculated. Others actually provide a view of the data within their control panels. If they don't, there's usually a bit of flexibility, to account for occasional spikes and such, but if you keep bumping up against the limits you'll be told to upgrade or move.

  • Well, I am trying to keep the question general because I need to understand my current host (Penguin Web) and evaluate if I am within the limits of other hosts I am considering. AFAIK, there is no way to see the usage and no metric limit at the current host.
