24 What's new in Zabbix 6.0.19

Aggregate functions

The count_foreach function now returns '0' for a matching item in the array, if no data are present for the item or the data do not match the filter. Previously such items would be ignored (no data added to the aggregation).

TimescaleDB 2.11 support

Support for TimescaleDB version 2.11 is now available.

Configurable TLS and connection parameters in MQTT plugin

The MQTT plugin for Zabbix agent 2 now provides additional configuration options, which can be defined in the plugin configuration file as named session or default parameters:

  • Connection-related parameters: broker URL, topic, username, and password;
  • TLS encryption parameters: location of the top-level CA(s) certificate, MQTT certificate or certificate chain, private key.

All of the new parameters are optional.

JavaScript preprocessing

The heap limit for scripts has been upped from 64 to 512 megabytes.

Support for Debian 12 (Bookworm) has been added, and official packages are available for download on Zabbix website.
