OpenView Network Node Manager: Designing and Implementing an Enterprise Solution

Book Description

  • Architecting, designing, implementing, and managing NNM solutions involving networks, desktop computers, and UNIX servers

  • All examples have been used in actual implementations

  • Covers capacity planning, firewall maintenance, cross-platform and best-practice issues

  • The only complete, practical guide to HP Network Node Manager!

    HP's OpenView Network Node Manager (NNM) is the industry's most powerful platform for enterprise-wide IP network management based on SNMP standards. Now, one of HP's leading NNM consultants has written the definitive, best-practices guide to implementing and managing OpenView NNM.

    OpenView Network Node Manager covers planning, architecture, deployment, configuration, administration, staffing, performance, firewalls, troubleshooting, and more. It also includes eight diverse case studies, straight from the author's extensive NNM experience in virtually every network environment: global manufacturers, computer firms, consultancies, engineering and scientific companies, colleges, and many more. Coverage includes:

  • Enterprise-class NNM deployment planning: requirements, operations agreements, hardware sizing and selection, piloting, and beyond

  • Staffing, training, management domains, and organizing network management for maximum efficiency

  • Deploying reliable, accurate, consistent and manageable Domain Name Services

  • Autodiscovering your network, refining the results to reflect your topology, and working with network maps

  • NNM day-to-day maintenance, event and performance management, optimization, and problem-solving

  • From day-to-day administration to long-term strategies, security to cross-platform issues, John Blommers delivers specific answers you can rely upon to maximize the value of OpenView NNM—and your entire enterprise network.
