How To Install Zabbix 5.0/4.0 on Ubuntu 18.04 / Ubuntu 16.04
Zabbix is an open-source enterprise-class monitoring software for servers, network devices, and applications. Zabbix uses Zabbix Agent installed on monitored hosts to collect the data. Also, it can monitor standard services such as SMTP or HTTP web services without having a client on the monitored host.
Additionally, Zabbix supports monitoring via SNMP, TCP, and ICMP checks, as well as over IPMI, JMX, SSH, and telnet. Zabbix can alert you with real-time notification using XMPP.
Zabbix is released under the GPL license v2.
Here, we will see how to install Zabbix Server Ubuntu 18.04 / Ubuntu 16.04.

Once you create a database for Zabbix installation, import the initial schema, and data into it.
cd /usr/share/doc/zabbix-server-mysql zcat create.sql.gz | mysql -u zabbixuser -p zabbix
Update Zabbix Configuration
Edit the zabbix_server.conf file to set the database details.
