This release is not for production use. It is a Release Candidate!

It is feature complete release but the default set of templates is not complete. More templates will be available in stable Zabbix 2.0.0.

The following sections describe the release in details and provide late-breaking or other information that supplements its main documentation. A brief overview of new functionality is available in Zabbix Wiki.

:: Added direct SNMP trap monitoring

New SNMP trap monitoring provides high performance way of collecting traps, pre-processors such as SNMPTT could be used as well.

:: Support of automatic selection of map icons

Maps and map elements could be optionally configured to automaticall select icons depending on element type (for example: host, network device, switch, etc).

:: Optional expanding of macros in map editing

Added new option in map configuration which enables macros expanding.

:: Host profiles renamed to inventory

Host profiles were renamed to a more standard "host inventory".

:: Performance improvements

Trigger related data is cached to reduce number of database requests, it improves overall performance of Zabbix Server.

:: New set of default templates

Existing default templates were improved to take advantage of low level discovery, also added new templates.

:: Automatic collection of host profile data

Information about hardware and software details can be automatically retrieved by Zabbix Agent and extended using user-defined parameters.

:: Enhanced auto-discovery

Added discovery based on HTTPS and Telnet checks, discovery configuration form is redesigned.

:: WEB monitoring by proxies

WEB scenarios could be monitored by remote proxies. It allows monitoring of WEB applications from various geographical locations.

:: Support of visible host and template name

In addition to standart host name, visible host name can be set to be displayed everywhere in the front-end. Additional macros for visible host name are also introduced.

:: Advanced options for remote commands

Remote commands (Agent, IPMI and SSH based) can be configured in a more flexible yet easier way.

:: Remote JMX monitoring

Zabbix JMX monitoring allows native secure remote monitoring of Java applications and popular middlewares such as JBoss, WebSphere and WebLogic.

:: Boolean data type

Boolean data type can be used for monitoring of two state metrics and JMX counters having boolean type.

:: New set of icons

New set of map icons is available for creation of great looking maps.

:: Support of new macros

Added support for {IPADDRESS}, {HOST.DNS} and {HOST.CONN} macros in trigger names. Macros {ITEM.ID} and {TRIGGER.EXPRESSION} can be used for notifications.

:: Unified host profiles

Normal and extended host profiles merged. Macros for referencing all profile fields introduced.

:: Multiple network interfaces

Multiple network interfaces can be assigned to a single host, therefore one host may have several IP addresses with different checks for each IP.

:: Better translation framework for WEB interface

Zabbix interface translations are handled by GNU gettext module.

:: Auto-registration with passive checks

Added support of monitoring auto-registered hosts with passive checks. It is very handy for monitoring of Cloud-like environments.

:: Re-design of unknown events and triggers

Unknown triggers and events will no longer be displayed in Zabbix WEB interface, a special flag will be shown if Zabbix is not confident about status of triggers or events.

:: Low level discovery

Zabbix is able to discover your file systems, network interfaces and SNMP interfaces automatically with no manual work. One template can be used for hosts having different devices. Lost resources could be automatically deleted based on configurable retention period.

:: Much faster processing of escalations

Processing of escalations has been improved to work more efficiantly.

:: Optional graph legends

Graph legend can be optionally disabled.

:: Templated host-level screens

Templates may contain screens for easy maintenance and quick access to a set of performance graphs. The screens are available via host popup available when clicking on a host.

:: Database integrity

There are significant improvements in the database schema for better consistency and security of configuration and historical data.

:: Nanosecond resolution for historical data

Zabbix supports nanosecond resolution for historical data. If you are migrating from 1.8.x the option will be off by default. It is on for fresh setups.

:: Multiple URLs for map elements

A map element may have multiple links (URLs) to external resources.

:: Support of user scripts on Zabbix Agent and IPMI-based commands

User scripts can be used to execute any command on a monitored host using Zabbix or IPMI agents.

:: Custom trigger severities

Standard trigger severities can be customized to have a different names and colors for displaying in Zabbix front-end.

:: New login screen

The login screen was re-designed to have a better look.

:: New design for all configuration forms

The new forms has much better look and usability.

:: Advanced labels setting for maps

Label formats can be individually configured for different types of map elements on map level.

:: Remembering of map grid options

Zabbix front-end will save grid-options for each map. Map import/export is extended to support new grid-related attributes.

:: Automatic filling of DNS name for discovered devices

Zabbix will automatically fill in DNS names of newly discovered and auto-registered devices.

:: Export of events to CSV

Events visible in Zabbix front-end can be exported to a CSV file with a mouse click.

:: Support of SQLite3 for use on server-side

SQLite3 can be used on Zabbix Server side and works also with Zabbix front-end. Might be useful for embedded environments and low profile hardware.

:: Advanced filtering supported by Zabbix API

Two new options (ALL, ANY) can be used to control filtering on API level.

:: Host area functionality for maps

All host group elements can be displayed in a map area.

:: Support of disabling media types

Media types can be optionally disabled.

:: Support of vm.memory.size

The item is now supported for various platforms including BSD.

:: Not supported items are handled nicely by Proxies

The processing was improved so that proxies will report to the server about not supported items.

:: More flexible dependencies

Dependency from template to host is supported.
