Overview of this book

This book is a perfect starting point for monitoring with Zabbix. Even if you have never used a monitoring solution before, this book will get you up and running quickly, before guiding you into more sophisticated operations with ease. You'll soon feel in complete control of your network, ready to meet any challenges you might face. Beginning with installation, you'll learn the basics of data collection before diving deeper to get to grips with native Zabbix agents and SNMP devices. You will also explore Zabbix's integrated functionality for monitoring Java application servers and VMware. Beyond this, Zabbix Network Monitoring also covers notifications, permission management, system maintenance, and troubleshooting - so you can be confident that every potential challenge and task is under your control. If you're working with larger environments, you'll also be able to find out more about distributed data collection using Zabbix proxies. Once you're confident and ready to put these concepts into practice, you'll find out how to optimize and improve performance. Troubleshooting network issues is vital for anyone working with Zabbix, so the book is also on hand to help you work through any technical snags and glitches you might face.

Adding new MIBs


One way to discover usable OIDs is to redirect the full SNMP tree output to a file, find out what interesting and useful information the device exposes, and determine what the OIDs are from that. It's all good as long as the MIB files shipped with Net-SNMP provide the required descriptors, but SNMP MIBs are extensible—anybody can add new information, and many vendors do. In such a case, your file might be filled with lines like this:

SNMPv2-SMI::enterprises.318.1.1.1.1.2.3.0 = STRING: "QS0547120198"

That's quite cryptic. While the output is in the short, textual form, part of it is numeric. This means that there is no MIB definition for this part of the SNMP tree. Enterprise number 318 is assigned to APC and, luckily, APC offers an MIB for download from their site, so it can be added to Net-SNMP configured MIBs. But how?

Tip

Getting SNMP MIBs isn't always easy. A certain large printer manufacturer representative claimed that they do not provide SNMP MIBs, and everybody should...
