Note: the 2nd Edition of this book is now available. If Amazon is out of stock, check out fogbooks.com. This guide is written for field consultants, users and administrators of the HP OpenView Network Node Manager (NNM) software product. This edition covers information that is relevant for NNM product versions 6.0 through 7.5. It was written for those who seek a shortcut to commonly used product info that is either missing or obfuscated in the product docs, and it covers practical implementation information that cannot be found in any product manuals or the product man/ref pages. This guide was gleaned from OpenView users, from the user community and from the authors thirteen years of compiled notes on the product. Note: this is the first edition of the book, which covers Version 7.5. Version 7.53 is included in the second edition - now available on Amazon.com.
