Overview of this book

Nowadays monitoring systems play a crucial role in any IT environment. They are extensively used to not only measure your system’s performance, but also to forecast capacity issues. This is where Zabbix, one of the most popular monitoring solutions for networks and applications, comes into the picture. With an efficient monitoring system in place you’ll be able to foresee when your infrastructure runs under capacity and react accordingly. Due to the critical role a monitoring system plays, it is fundamental to implement it in the best way from its initial setup. This avoids misleading, confusing, or, even worse, false alarms which can disrupt an efficient and healthy IT department. This new edition will provide you with all the knowledge you need to make strategic and practical decisions about the Zabbix monitoring system. The setup you’ll do with this book will fit your environment and monitoring needs like a glove. You will be guided through the initial steps of choosing the correct size and configuration for your system, to what to monitor and how to implement your own custom monitoring component. Exporting and integrating your data with other systems is also covered. By the end of this book, you will have a tailor-made and well configured monitoring system and will understand with absolute clarity how crucial it is to your IT environment.

Sending data using zabbix_sender


Until now, you have seen how to implement external checks on both the server side and the agent side, which involves moving the workload from the monitoring host to the monitored host. You can understand how both methods in the case of heavy and extensive monitoring are not the best approach since we are thinking of placing Zabbix in a large environment. Most probably, it is better have a server dedicated to all our checks and use those two functionalities for all the checks that are not widely run.

Zabbix provides utilities designed to send data to the server. This utility is zabbix_sender, and with it, you can send the item data to your server using the items of a Zabbix trapper type.

To test the zabbix_sender utility, simply add a Zabbix trapper item to an existing host and run the command:

zabbix_sender -z <zabbixserver> -s <yourhostname> -k <item_key> -o <value>

You will get a response similar to the following:
