5 What's new in Zabbix 5.2.0

Zabbix 5.2.0 is not released yet.

Time zone definition

The frontend time zone now can be set globally and also adjusted for different users.

The default global timezone:

  • can be set manually when installing the frontend
  • can be modified in AdministrationGeneralGUI

User-level time zone:

Export to YAML

Zabbix configuration elements now can also be exported and imported in the YAML format, which is easy to read and edit.

Modbus support

Zabbix now supports Modbus out-of-the-box using the new modbus.get[] agent and agent 2 item.

See also:

MQTT support

Zabbix now supports receiving values of MQTT topics using the new mqtt.get[] Zabbix agent 2 item key.

Digest authentication for HTTP agent

Digest authentication is now supported for HTTP agent items and in web scenarios.

Support of tags for host prototypes

Host prototypes now support tags with a possibility to use LLD macros as tag values. This functionality allows to assign each discovered host own set of tags with valuable information (datacenter, instance type, resource type, etc.), which can be useful, for example, in the discovery of cloud resources.

Macros

  • {ITEM.LOG.*} macros are now also supported in:
    • trigger names, operational data, URLs and descriptions
    • event tags and values
  • User macros are now supported in item and low-level discovery rule descriptions
  • New macros have been added:
    • {ITEM.DESCRIPTION.ORIG<1-9>} resolves to the item description without macros expanded
    • {LLDRULE.DESCRIPTION.ORIG} resolves to the low-level discovery rule description without macros expanded

User macro length limit raised

The maximum allowed length of user macro values has been increased from 255 to 2048 characters.

Frontend

Minimum required PHP version

The minimum required PHP version has been upped from 7.2.0 to 7.2.5.

Informative tabs

Tabs in many frontend forms now indicate the number of defined elements or if the functionality is enabled. To illustrate let's compare a host configuration form with two linked templates, one host tag, one host-level macro, enabled inventory and two-way encryption enabled now and before:

Informative tabs allow to debug problems easier, for example, when an item has preprocessing steps defined they are now clearly indicated with a number even when the tab is not opened:

Informative tabs have been added to the configuration forms for:

  • Hosts and host prototypes
  • Templates
  • Items and item prototypes
  • Triggers and trigger prototypes
  • Discovery rules
  • Web scenarios
  • Actions
  • Services
  • Proxies
  • Authentication
  • Users and user groups
  • Media types
  • Graph widgets
  • Maps
  • User settings

Zabbix session is now stored in a user cookie.

Ability to change the default language

It is now possible to choose the default language for the Zabbix frontend during the installation process. After the installation, the system default language can be changed in the Administration→General→GUI section. If a user has not specified another language in the profile settings, the system-wide setting is used. Login page for all users is displayed in the chosen default language.

New configuration parameters

Several parameters, that previously could only be modified through editing defines.inc.php file, can now be configured directly via the frontend. This makes Zabbix frontend configuration more flexible and ensures that custom changes will be preserved after an upgrade.

AdministrationGeneral frontend section has been modified to accommodate more parameters:

  • General → GUI page now
    • includes Working hours field (used to be on a separate page);
    • contains new parameters: Max number of columns and rows in overview tables, Show technical errors, Max history display period, Default period (for graphs and dashboards), Max period (for graphs and dashboards).
  • Working time page has been removed.
  • Trigger severities page is moved to Trigger displaying options.
  • Other page now includes three additional parameter groups:
    • Authorization, which allows to set number of failed login attempts and period of blocking login page after exceeding this limit;
    • Security, which allows to set URI scheme validation rules, X-Frame-Options HTTP header, and custom iframe sandboxing restrictions;
    • Communication with Zabbix server, which allows to customise timeout limits.

Adding hosts without interfaces

It is now possible to add a host without interfaces, which may be useful for hosts with only trapper items or web checks.

For a new host now no interfaces are defined by default. To add a new interface, click on Add in the Interfaces block and select the interface type from a dropdown.

Dashboard navigation and details

Switching to the required dashboard has become easier with these new features:

  • List of all dashboards now has a filter, allowing to search for dashboards by name and to switch between displaying all dashboards and dashboards created by the current user.
  • Dashboards created by the current user have a tag “My” next to a name

Additionally, it is now immediately visible, which dashboards are shared with other users. If a dashboard is public or is privately shared with any user or user group - a tag “Shared” next to the dashboard name will indicate that.

Simplified Maintenance periods form

The Maintenance periods configuration form now has a simpler single-tab look. All configuration parameters previously located on the tabs Periods and Hosts and groups have been moved to the primary tab.
