Chapter 1. 3scale glossary

This section acts as a glossary of common terms used within the 3scale platform. Following is the structure of glossary entries:

  • A glossary term
  • One or more of each or both of the following items:

    • A definition of the term, optionally followed by one or two explanatory sentences and a See also reference that points to a related term or terms. Example:

hit: The built-in metric to which all methods report. Additional top-level metrics can be added here in order to track other usage that should not increase the hit count. See also Section 1.14.4, “metric”.

In this case, hit is related to metric because hit is a built-in metric.

  • A See reference that points to a preferred synonym for that term or to the spelled-out version of an abbreviated term. Example:

account: See Section 1.21.1, “tenant account”, Section 1.5.2, “developer account”.

In this case, the reader is redirected from account to either of the relevant terms containing qualifiers.

  • If there is more than one definition for a term, each item is numbered.
