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. Network monitoring doesn't have to be a chore - learn the tricks of the Zabbix trade and make sure you're network is performing for everyone who depends upon it.

SSH and Telnet items


We have looked at quite a lot of fairly custom and customizable ways to get data into Zabbix. Although external checks should allow us to grab data by any means whatsoever, in some cases we might need to collect data from some system that is reachable over SSH or even Telnet, but there is no way to install an agent on it. In that case, a more efficient way to retrieve the values would be to use the built-in SSH or Telnet support.

SSH items

Let's look at the SSH items first. As a simple test, we could re-implement the same Zabbix agent parameter we did as our first user parameter, determining the number of the currently logged-in users by running who | wc -l. To try this out, we need a user account we could use to run that command, and it is probably best to create a separate account on "A test host". Creating one could be as simple as the following:

# useradd -m -s /bin/bash zabbixtest
# passwd zabbixtest

Note

Do not create unauthorized user accounts in production systems...
