Applicability of Standards Track MIBs to Management of World Wide Web Servers
Alternative Format: Original Text Document
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.
