# Docker by Zabbix agent 2
## Overview
The template to monitor Docker engine by Zabbix that work without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
Template `Docker by Zabbix agent 2` — collects metrics by polling zabbix-agent2.
## Requirements
Zabbix version: 7.0 and higher.
## Tested versions
This template has been tested on:
- Docker 23.0.3
## Configuration
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
## Setup
Setup and configure Zabbix agent 2 compiled with the Docker monitoring plugin. The user by which the Zabbix agent 2 is running should have access permissions to the Docker socket.
Test availability: `zabbix_get -s docker-host -k docker.info`
