This book is designed as a hand-on guide to three OpenView products: Network Node Manager (NNM), Customer Views (CV), and Service Information Portal (SIP). The book begins with a review of network management and Simple Network Management Protocol (SNMP). Simple Network Management Protocol (SNMP) is the protocol governing network management and the monitoring of network devices and their functions. While NNM provides the physical layout of the networked enterprise, Customer Views (CV) provides a logical view of devices based on customer ownership. CV provides the ability to define which customers will be affected by which resources. This book covers CV's additional containers to the NNM root submap, including: Key Resources, Customers, Devices, Internet Links, and Sites. Because CV allows you to configure a restricted view of the network, this aspect of the book will appeal to Managed Service Providers (MSPs). This book also covers Service Information Portal (SIP), which provides a web accessible interface to some of the data available in NNM and CV. SIP also contains gauges to display the overall health of Key Resources, Customer Premises Equipment, Routers, Interfaces and Servers as defined in NNM and CV.
