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.

While many configuration parameters for a proxy are the same as for the server (the pollers to start, port to listen on, and so on), and some are the same as for the agent daemon (hostname), there are some proxy-specific parameters. Knowing about these can be helpful when diagnosing a proxy-related problem, or when the proxy must be deployed in a specific environment. For an active proxy, the following parameters affect it:

Option

Description

ProxyLocalBuffer

Proxy will keep data in the local database for this many hours. By default, all data that is synchronized to the Zabbix server is removed. This could be useful if we would like to extract some data that is not stored permanently on the Zabbix server, such as network discovery values.

ProxyOfflineBuffer

Proxy will keep data for this many hours if the Zabbix server is unavailable. By default, data older than one hour is discarded.

HeartbeatFrequency

By default, the Zabbix proxy sends a heartbeat...
