Introduction

This page walks you through the steps required to start basic monitoring of Linux machines with �����IJ�. The steps described in this tutorial can be applied to any Linux-based operating system.

Who this guide is for

This guide is designed for new �����IJ� users and contains the minimum set of steps required to enable basic monitoring of your Windows machine. If you are looking for deep customization options or require more advanced configuration, see Configuration section of �����IJ� manual.

Prerequisites

Before proceeding with this installation guide, you must download and install �����IJ� server and �����IJ� frontend according to instructions for your OS.

Install �����IJ� agent

�����IJ� agent is the process responsible for gathering data.

Check your �����IJ� server version:

zabbix_server -V

Install �����IJ� agent of the same version (recommended) on the Linux machine that you want to monitor. Based on your monitoring needs, it may be the same machine, where �����IJ� server is installed, or a completely different machine.

Choose the most suitable installation method:

• Run as a Docker container - see the list of available images in .

• Install from �����IJ� packages (available for Alma Linux, CentOS, Debian, Oracle Linux, Raspberry Pi OS, RHEL, Rocky Linux, SUSE Linux Enterprise Server, Ubuntu).

• Compile from sources.

Configure �����IJ� for monitoring

�����IJ� agent can collect metrics in active or passive mode (simultaneously).

Monitoring templates provided by �����IJ� usually offer two alternatives - a template for �����IJ� agent and a template for �����IJ� agent (active). With the first option, the agent will collect metrics in passive mode. Such templates will deliver identical monitoring results, but using different communication protocols.

Further �����IJ� configuration depends on whether you select a template for active or passive �����IJ� agent checks.

�����IJ� frontend

1. Log in to �����IJ� frontend.

2. Create a host in �����IJ� web interface.

This host will represent your Linux machine.

3. In the Interfaces parameter, add Agent interface and specify the IP address or DNS name of the Linux machine where the agent is installed.

4. In the Templates parameter, type or select Linux by �����IJ� agent.

�����IJ� agent

Open �����IJ� agent configuration file (by default, the path is /usr/local/etc/zabbix_agentd.conf):

sudo vi /usr/local/etc/zabbix_agentd.conf

Add the IP address or DNS name of your �����IJ� server to the Server parameter.

For example:

Server=192.0.2.22

�����ƥ��֥����å�

�����IJ� frontend

1. Log in to �����IJ� frontend.

2. Create a host in �����IJ� web interface.

This host will represent your Linux machine.

3. In the Templates parameter, type or select Linux by �����IJ� agent active.

�����IJ� agent

Open �����IJ� agent configuration file (by default, the path is /usr/local/etc/zabbix_agentd.conf):

sudo vi /usr/local/etc/zabbix_agentd.conf

Add:

• The name of the host you created in �����IJ� web interface to the Hostname parameter.
• The IP address or DNS name of your �����IJ� server to the ServerActive parameter.

For example:

ServerActive= 192.0.2.22
       Hostname="Linux server"

View collected metrics

Congratulations! At this point, �����IJ� is already monitoring your Linux machine.

To view collected metrics, open the Monitoring->Hosts menu section and click on the Latest data next to the host.

This action will open a list of all the latest metrics collected from Linux server host.

Set up problem alerts

�����IJ� can notify you about a problem with your infrastructure using a variety of methods. This guide provides configuration steps for sending email alerts.

1. Go to the User settings -> Profile, switch to the tab Media and add your email.

2. Follow the guide for Receiving problem notification.

Next time, when �����IJ� detects a problem you should receive an alert via email.

Test your configuration

On Linux, you can simulate high CPU load and as a result receive a problem alert by running:

cat /dev/urandom | md5sum

You may need to run several processes for CPU load to exceed the treshold.

When �����IJ� detects the problem, it will appear in the Monitoring->Problems section.

If the alerts are configured, you will also receive the problem notification.
