Zabbix 4.4 to be Rolled Out

After 6 months of development, a new version of the Zabbix 4.4 monitoring system is available, the code of which is distributed under the GPLv2 license. Zabbix consists of three basic components: a server for coordinating checks, generating test requests and collecting statistics; agents for performing checks on the side of external hosts; frontend for organizing system management.

To relieve the load from the central server and form a distributed monitoring network, a series of proxy servers can be deployed that aggregate data about the verification of the host group. Data can be stored in MySQL, PostgreSQL, TimescaleDB, DB2, and Oracle. Without agents, the Zabbix server can receive data using protocols such as SNMP, IPMI, JMX, SSH / Telnet, ODBC, and test the availability of Web applications and virtualization systems.
