Open-source integrated monitoring software "Zabbix7"
Zabbix is open-source integrated monitoring software for centralized monitoring of servers, networks, and applications. It provides the monitoring, fault detection, and notification functions necessary for integrated monitoring. With Zabbix agents supporting numerous platforms and SNMP compatibility, it enables monitoring of entire systems using just Zabbix.
To run Zabbix, you need the PHP programming language, a MySQL/MariaDB database server, and a web server such as Apache or Nginx.
This guide assumes all of the following conditions are already configured.

Create a database and user for Zabbix
1.Creating and Initializing the Zabbix Database
database my_zabbix_db
user zabbix_user
password ?WWabcd123
# mysql -u root -p
Password:
>CREATE DATABASE my_zabbix_db;
>CREATE USER 'zabbix_user'@'localhost' IDENTIFIED BY '?WWabcd123';
>GRANT ALL PRIVILEGES ON my_zabbix_db.* TO 'zabbix_user'@'localhost';
>set global log_bin_trust_function_creators = 1;
>exit;
Initialization
# cd /usr/local/share/zabbix74/server/database/mysql
# mysql -uzabbix_user -p?WWabcd123 my_zabbix_db < schema.sql
# mysql -uzabbix_user -p?WWabcd123 my_zabbix_db < images.sql
# mysql -uzabbix_user -p?WWabcd123 my_zabbix_db < data.sql
After importing the database schema, disable the log_bin_trust_function_creators option.
# mysql -uroot -p
password
mysql> set global log_bin_trust_function_creators = 0;
mysql> exit;

Add monitored hosts
Add the following servers as targets
OS : FreeBSD14.3
IP Address : 192.168.11.85
Host name : Lion
1.Configuration on the server to be monitored
1.1 Install Zabbix Agent
# pkg install -y zabbix74-agent
1.2 Editing the Zabbix Agent Configuration File
# vi /usr/local/etc/zabbix74/zabbix_agentd.conf
Line 113: Specify the Zabbix server (in this case, 192.168.11.83)
Server=192.168.11.83
Line 169: Specify the Zabbix server (in this case, 192.168.11.83)
ServerActive=192.168.11.83
Line 178: Change to your own hostname (in this case, Lion)
Hostname=Lion
# service zabbix_agentd enable
zabbix_agentd enabled in /etc/rc.conf
# service zabbix_agentd start
1.3 Configure the firewall on the Zabbix agent side
You must allow Zabbix ports 10050 (Zabbix server side) and 10051 (Zabbix agent side).(xxx,*** must specify a number that does not overlap with others.)
# vi /usr/local/etc/ipfw.rules
$IPF xxx allow tcp from any to any 10050 in
$IPF xxx allow tcp from any to any 10050 out
$IPF *** allow tcp from any to any 10051 in
$IPF *** allow tcp from any to any 10051 out
# service ipfw restart
2. Configuration in the Zabbix Web UI
2.1 Log in to the Zabbix management site, select [Datacollection] - [Hosts] in the left pane, and click the [Create Host] button at the top of the right pane.
2.2 Enter the hostname in [Hostname] (Lion in this case), and set the name to be displayed in [Visible name] (Lion in this case).
2.3 [Templates] Click the [Select] button. For [Template group], click [Select] and choose [Templates]. From the list of monitoring templates, select [Linux by Zabbix agent] to monitor common items like CPU on Linux OS. Click [Select] at the bottom.

2.5 [Interfaces] Click [Add] within Interfaces, select [Agent], enter the IP address to monitor and the hostname in [DNS name], then click [Add] at the bottom.
2.6 A new monitored server has been registered.
After a short while, data for the added host will begin to appear.
Click [Monitoring][Hosts] in the left pane, then click the added monitored host in the right pane and click [Graphs].
Add monitored items
This time, we will add the Apache httpd service on the Zabbix server to the list of monitored services.
1. Enable server-status in Apache httpd on the Zabbix server to be monitored
Edit the Apache configuration file httpd.conf
# vi /usr/local/etc/apache24/httpd.conf
Line 161: Verify that the status_module is enabled.
LoadModule status_module libexec/apache24/mod_status.so
Add the following to the last line
<Location /server-status>
SetHandler server-status
Require local
</Location>
# service apache24 restart
2.Log in to the Zabbix management site, click [Data collection] - [Hosts] in the left pane, and then click the host you want to add monitoring items to in the right pane (in this case, the Zabbix server).
3.Click the [Select] button in the [Templates] section
4.Click the [Select] button
5.Click [Templates/Applications]
6.Select [Apache by HTTP], then click [Select].
7.Click the [Update] button to update your settings.
8.[Apache by HTTP] Click the link
Open the [Macros] tab, enter [127.0.0.1] in {$APACHE.STATUS.HOST}, then click [Update].
In the left pane, click [Monitoring] > [Hosts]. In the right pane, click [Zabbix server] and select [Graphs].
