Zabbix FreeBSD monitoring

Monitoring FreeBSD systems.

Items, triggers and graphs for monitoring various basic FreeBSD operating system parameters. Including low-level discovery rules for file systems and network interfaces.

The template uses macros (with macro contexts where feasible) for trigger thresholds which can be easily adapted to your specific needs.

This template is part of RaBe's Zabbix template and helpers collection.

Usage

Import the Template_OS_FreeBSD_active.xml into your Zabbix server (click on the Raw button to download).
Add the template to your host (or stack template)
Check if new data arrives
