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.

Tying it all together


So, we found out that a normal or passive agent waits for the server to connect, while an active agent connects to the server, grabs a list of items to check, and then reconnects to the server periodically to send in the data. This means that using one or the other kind of Zabbix agent item can impact performance. In general, active agents reduce the load on the Zabbix server because the server doesn't have to keep a list of what and when to check. Instead, the agent picks up that task and reports back to the server. But you should evaluate each case separately: if you only have a few items per host that you monitor very rarely (the update interval is set to a large value), converting all agents to active ones that retrieve the item list more often than the items were previously checked won't improve Zabbix server performance.

Note

It is important to remember that you can use a mixture of various items against a single host. As we just saw, a single host can have normal...
