About This Guide

This chapter provides information on the following topics:

Document Objectives

This book describes the data areas used by the CiscoWorks Blue Internetwork Status Monitor (ISM) product.

Audience

This guide is intended for network engineers and Multiple Virtual Storage (MVS) system programmers who are responsible for installing and configuring Cisco routers in a Systems Network Architecture (SNA) environment. This guide assumes that you are familiar with the basic concepts and terminology used in internetworking and that you understand the network topology and protocols.

Document Organization

This guide is divided into the following chapters:

"Control Blocks," describes the control blocks used by ISM to monitor resources.
"VSAM Control Files," describes the control files used by ISM to save information for each resource. The control fi8les are written to VSAM.
"Statistics Written to VSAM and SMF," describes the record formats for performance, statistics, and log data that is written to VSAM and SMF.

The terms resource and router are used throughout this documentation. To avoid confusion, be aware that all routers are resources, therefore the term resource encompasses router—whereas the term router is specific.

This guide uses basic conventions to represent text and table information.
