A Model for Common Operational Statistics

RFC 1857                 Operational Statistics             October 1995


   There exist a variety of network management tools for the collection
   and presentation of network management metrics.  However, different
   kinds of measurement and presentation techniques make it difficult
   to compare data among networks.  In addition, there is not general
   agreement on what metrics should be regularly collected or how they
   should be displayed.

   There needs to be an agreed-upon model for

   1)   A minimal set of common network management metrics to satisfy
        the goals stated above,

   2)   Tools for collecting these metrics,

   3)   A common interchange format to facilitate the usage of these
        data by common presentation tools and

   4)   Common presentation formats.

   Under this Operational Statistics model, collection tools will
   collect and store data to be retrieved later in a given format by
   presentation tools displaying the data in a predefined way.  (See
   figure below.)
