9780596008406: Essential SNMP, Second Edition

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.

O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include:

  • Expanded coverage of SNMPv1, SNMPv2, and SNMPv3
  • Expanded coverage of SNMPc
  • The concepts behind network management and change management
  • RRDTool and Cricket
  • The use of scripts for a variety of tasks
  • How Java can be used to create SNMP applications
  • Net-SNMP's Perl module

The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents.

Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

Review:

Without Simple Network Management Protocol (SNMP), network administrators might have to actually get out of their chairs and go see what's up with all of the network-connected equipment under their authority. Perish the thought. Essential SNMP explains how the management protocol works and how it's implemented by several operating systems and pieces of equipment. More importantly, this book shows its reader--who should be a network administrator who's familiar with the problems of running a distributed network--how SNMP can earn its place as a network administration tool. In other words, this book examines SNMP as a strategic resource as well as a technical phenomenon.

Because it's oriented toward SNMP as a tool, much of the coverage in this book has to do with software that uses SNMP to provide network monitoring and control services. After a strengths-and-weaknesses overview of a number of SNMP packages, the authors use mainly HP OpenView, Castle Rock SNMPc, and Net-SNMP (the last in combination with Perl scripting) to demonstrate how SNMP works and how to take advantage of it. It's the scripting that really distinguishes this book from other SNMP books, by the way. It's integral to the authors' presentation, and the latter half of this book is packed with shell and Perl listings. --David Wall

Topics covered: Simple Network Management Protocol (SNMP) and its applicability as a network management tool. Details like object identifiers (OIDs), management information bases (MIBs), traps, and community strings are defined and explained. The configuration of SNMP agents is detailed for several software packages and operating systems, and the integration of SNMP and scripts (in shell languages and in Perl) is covered nicely.
