RFC 2039                     WWW Track MIBs                November 1996


3. Requirements

   WWW servers can be viewed from several perspectives when assigning
   management responsibilities.  For the sake of discussion, these
   perspectives are named the Operational Model and the Service Model.
   The Operational Model views WWW servers as computers with hardware,
   disk, OS and web server software.  This model represents the actual
   resources that make up the machine so that it can be monitored from
   the perspective of resource utilization.  The Service Model views the
   WWW server as a black box that simply handles the responses to
   requests from clients located on the web.

   The two models compliment each other while providing distinct
   information about the server.  Members of the organization
   responsible for the WWW server, may be interested in one and/or both
   of the management models.  For this reason, the management
   information should be scalable, for one or both models to be
   implemented independent of the other.

   With this in mind, the requirements for WWW server management can are
   summarized below by expanding upon those generated at the HTTP-MIB
   BOF.

3.1  Operational Model Requirements

3.1.1. Host specific and Application Monitoring

   This includes monitoring the utilization of CPU, disk and network
   capacity.

3.1.2. Dependencies among applications.

   Some systems implement a number of services within a single piece of
   code. Others use multiple pieces of code to implement the same set of
   services. Because of this, dependencies develop among processes.
   These dependencies become critical when a particular process needs to
   be stopped, restarted or reconfigured. These dependencies need to be
   defined within the management information so that management
   applications can operate the systems correctly.

3.1.3. Error generation and reporting

   The WWW server generally reports errors via logging facilities.  The
   format of the log file is not well defined.  It is required that a
   standard facility for error reporting be utilized.
