OpenBSD by Zabbix agent
Overview
It is an Official OpenBSD template. It requires Zabbix agent 7.0 or newer.
Requirements
Zabbix version: 7.0 and higher.
Tested versions
This template has been tested on:
- OpenBSD
Configuration
Zabbix should be configured according to the instructions in the Templates out of the box section.
Setup
Install Zabbix agent on OpenBSD according to Zabbix documentation.
Macros used
| Name | Description | Default |
|---|---|---|
| {$AGENT.TIMEOUT} | The timeout after which the agent is considered unavailable. It works only for the agents reachable from Zabbix server/proxy (in passive mode). |
3m |
