New in Zabbix 3.2.1 (Oct 19, 2016)

New in Zabbix 3.2.1 RC 1 (Sep 28, 2016)

New in Zabbix 3.2.0 (Sep 14, 2016)

Event tags for greater flexibility:
Custom tags for events are introduced in the new version. Custom event tags are implemented as a pair of the tag name and value. You can use only the name or pair it with a value. After the tags are defined on the trigger level, corresponding events get marked with tag data.
The tags can be use to implement service-centric approach to management of notifications and displaying of problems.
Global event correlation:
New global event correlation module allows pre-processing of problems based on event tag information. As a result of pre-processing a new problem or older problems matching correlation rules can be closed automatically.
Event correlation on trigger level:
Configuration of triggers was extended to support ability of closing problem only if OK and PROBLEM event tags match each other. That allows much more flexible matching of problems and recovery conditions for log monitoring and trap processing.
Ability to manually close problems:
Some problems, if allowed on trigger level, can be closed manually from Zabbix UI. It greatly simplifies workflow for trap processing, also for processing of errors reported in log files.
Independent escalation for each problem event:
Zabbix will process and escalate individually each problem generated by trigger having problem event generation mode set to 'multiple'.
Ability to customize macro values:
Sometimes a macro may resolve to a value that is not necessarily easy to work with. It may be long or contain a specific substring of interest that you would like to extract. For these purposes, the new version comes with a new concept of macro functions.
Coping with fast-growing log files:
More advanced options are available for dealing with fast-growing log files.
An optional maxdelay parameter for log monitoring items, which can be used to set a time bracket that log records must be analyzed within - if it's impossible to analyze all records within the set time, older lines are skipped in favour of analyzing the more recent ones.
Also, two new agent items log.count and logrt.count that count the number of matched lines and return that number instead of the lines themselves.
Easier trigger hysteresis:
A much easier way of defining trigger hysteresis is introduced by an optional second trigger expression called 'recovery expression' where you can separately define the conditions that have to be met for the trigger to return back to the OK state.
There is also more control over how OK events are generated. You can use the problem expression as basis (then it works the same way as before), the recovery expression as basis, or even select 'None' in which case the trigger will always remain in problem state if it goes into it.
Additionally, PROBLEM event generation mode for single/multiple problem events has been changed from a silent default/optional checkbox into an obvious two-way choice.
For more information see configuring a trigger and trigger hysteresis sections.
Delaying escalations during maintenance:
The logic of delaying problem notifications during host maintenance has been changed. The old mechanism is dropped. Instead there is an new option in action configuration, which allows to pause notifications in the host maintenance phase if you wish so. If notifications are paused during maintenance, they get back on course after the maintenance, according to the escalation scenario.
Viewable items, triggers, graphs created by LLD:
Now entities created by low-level discovery are shown in a much more user-friendly way. It is possible to view the details of these items, triggers and graphs. Check-boxes are enabled to apply mass operations to them. Thus it is possible to enable/disable/delete them.
Web scenario export/import:
When exporting hosts or templates into XML, web scenarios are now exported as well. When importing hosts/templates, there are options for creating new, updating existing and deleting missing web scenarios.
Now on you may easily share web scenarios on share.zabbix.com. For example, export a template with the web scenarios into XML and upload to share.zabbix.com. Then others can download the template and import the XML into Zabbix.
Front-end improvements:
Several frontend sections have gained a filter allowing to search by name as well as status, type or mode. Host groups, templates and global scripts can now be searched by name.
Introduced new high-performance view of current, recently resolved problems and history of problems under Monitoring->Problems. Monitoring->Events no longer exists.
The problem view introduces timeline that makes problems much easier to spot and understand.
No acknowledgement for OK events:
Removed ability to acknowledge Ok events. Original problem should be acknowledged instead.
API improvements:
New API method 'problem.get' is introduced to allow retrieval of problem related information.
Improvements for trigger functions:
Added two new options "regexp" and "iregexp" to the third parameter of trigger function count().
More efficient table structure for history text and history log:
Unused id field was removed to make history tables more efficient.
Interface for real-time history export:
Implemented interface for history export through loadable modules and changed module loading to require only zbx_module_api_version() function.
Enabled evaluation of function nodata() for not supported items:
Function nodata() will be normally evaluated even if a corresponding item is unsupported for some reason.
Added evaluation of logical expressions with unsupported items in trigger expressions and calculated items:
Zabbix will correctly evaluate trigger expressions if one of items is unsupported.
Added datacenter name for VMWare hypervisors and virtual machines:
Introduced new items vmware.hv.datacenter.name and vmware.vm.datacenter.name. Also added support of new discovery field {#DATACENTER.NAME} for hypervisor and virtual machine discovery.
Less verbose trap processing:
Added one minute delay for repeated SNMP trap file error log entries.
Flexible aliases for agents:
Added support for flexible aliases that may or may not pass parameters to the aliases item.
Updated translations:
Updated translations to many languages.

New in Zabbix 3.0.1 (Mar 1, 2016)

New in Zabbix 3.0.0 (Feb 16, 2016)

Redesign of Zabbix front-end:
Zabbix WEB interface has been improved for much better usability and user experience along with other enhancements.
Encryption and authentication:
Introduced out of the box support of encryption and authentication for server, proxy and agent communications. Both certificate based and PSK encryption are supported with easy upgrade path from non encrypted setups. No need to use third party tools or VPN solutions anymore.
Forecasting and trend prediction:
New set trigger functions timeleft() and forecast() enable support of forecasting and trend prediction. It is possible to predict item value in the future. Also Zabbix may tell when item value reaches certain threshold.
Ready for business checks:
Items can be scheduled to be executed at a specific time. Zabbix provides rich scheduling options defined on per individual item level.
Support of private and public maps, screens and slideshows:
Maps, screens and slideshows can be created with flexible sharing options.
Defining dependencies between trigger prototypes:
Ability to define dependencies has now been implemented for trigger prototypes. A trigger prototype may depend on another trigger prototype from the same low-level discovery (LLD) rule or on a regular trigger.
The processing of trigger prototypes has been optimized by reducing the number of database queries. As a result, the process of creating triggers takes only half of the time as before.
Linking to applications based on discovery values:
To help with logical grouping of items created from item prototypes by low-level discovery (LLD), it is now possible to assign the discovered items to applications that are based on the values of LLD macros.
In addition to the options for linking to regular applications, a new option for creating application prototypes has been added to item prototype definition. Discovered items are linked to the applications created based on application prototypes.
Multiple OID support in SNMP discovery:
SNMP discovery was improved to support discovery of multiple OIDs. For more information, see low level discovery documentation.
Ability to graph log items:
Log items (log, logrt, and eventlog) and item prototypes can now be saved with any type of information (not only “Log”), in line with the possibilities offered by the optional output parameter. It means that log items could also be saved with type of information set to integer (“Numeric (unsigned)”), and thus be graphed.
Added support of context for user macros:
User macros got extra flexibility by introducing optional context.
Resolution of user macros made transparent:
To make the resolution of macros transparent, there is now a new option in host and template configuration forms with macro resolution details.
SMTP authentication options:
Configuring e-mail as a media type for sending notifications has been extended with new SMTP authentication options. It is also possible now to specify the server port other than the hardcoded 25 before.
Multiple escalator support:
Multiple escalator processes supported for better scalability of event processing.
VMware monitoring improvements:
A new simple check to monitor VMware virtual machine CPU ready state was added. For more information see VMware monitoring item keys.
Dropping IE8 support:
Support for Microsoft Internet Explorer 8 will not be provided anymore.
Filtering options:
Continuing with the work of improving filtering options across several frontend sections, a new filter has been added to the Triggers top 100 report. While previously it was only possible to filter here by some predefined time period, now you may filter by host group, host, trigger severity, predefined time period and custom time period.
Also filtering was introduced for Maps, Screens and Slide shows.
Mass editing buttons instead of dropdown:
Options for mass-editing of entities in lists are now displayed as buttons. The previous option of a dropdown selection and then having to click on Go has been removed. It is expected that reinstating buttons for these operations will make it much quicker and easier to use these options.
User agent options in web monitoring:
In web scenario definition it is now possible to select a 'Zabbix' user agent. That may be useful for filtering out requests coming from Zabbix in web server access log files. The 'Zabbix' agent now is the default choice for the frontend and API, unless specified otherwise.
XML import/export:
Import/export support processing of value maps. Also added support of the Clock screen element with a “Host time” option for import and export.
Zabbix API improvements:
Added support of value maps and trends to Zabbix API.
Miscellaneous front-end improvements:
Added paging, mass operations and column 'Used in items' to the list of value maps.
Switching inventory mode in the host mass update form will no longer refresh the whole form.
Aggregate items do not require the fourth parameter (timeperiod) if the third parameter (itemfunc) is set to 'last'.
Translation of the byte unit prefixes - K for kilobytes, M for megabytes, etc. - has been removed because the “bytes” unit was not translated.
Spaces can now be used in IP ranges in network discovery and actions conditions (e.g., “192.168.0.0/24, 192.168.1.0/24”).
Implemented trigger description and URL popups in the dashboard's "Last 20 issues" and screen element's "Host group issues" and "Host issues".
Minimum period for time navigator set to 5 minutes, also added more pre-defined time periods for fast selection.
All actions could be performed only by using POST variables thus improving overall security.
Forced housekeeper execution:
An additional runtime control option (housekeeper_execute) has been added to Zabbix server and Zabbix proxy to support manual housekeeping procedure execution. In this case the period of outdated history deleted in one housekeeping cycle will be 4 times the period since the last housekeeping cycle, but not less than 4 hours and not greater than 4 days.
The automatic housekeeping procedures can now be disabled by setting the configuration file HousekeepingFrequency parameter to zero.
Default configuration file improvements:
Default configuration files have been changed to improve security and usability.
Performance improvements:
Reduced the number of poller configuration cache locks by 1/3 resulting in visible peroformance improvement for heavy duty Zabbix servers and proxies. Also optimized history cache and history syncers to better handle few items flooding cache with values.
Significantly improved performance of action processing by introducing in-memory cache of actions and action conditions.
The process of trigger expression evaluation has been improved dramatically by using a hashing mechanism. Also configuration cache locking during that process has been reduced multiple times.
The nodata() function calculation was improved to limit the database requests to the range specified in nodata() function.
When an active proxy connects to Zabbix server information about this proxy is retrieved from server configuration cache (in earlier versions it was retrieved directly from database). This improves performance and reduces database load. On the other hand, active proxy configuration change now has not instant effect. It has to wait until server configuration cache is synchronized with database (can be enforced from commandline).
Value cache improvements:
When working in low memory mode value cache will attempt to switch back to normal operational mode once per day. The current operational mode can be checked with zabbix[vcache,cache,mode] key.
Ability to run Zabbix daemons in foreground:
Added an option to start Zabbix daemons in foreground mode and a configuration parameter to log to the standard ouput. It simplifies dockerization of Zabbix components very much.
Zabbix agent crash log on Windows platforms:
Zabbix agent will now log crash information on Windows similar to the one generated by agents on Unix-like platforms.
TCP connection timeout on Windows platforms:
The configured timeout option is now properly applied when estabilishing TCP connections on Windows platform.
This affects the following Zabbix agent keys: net.tcp.port, net.tcp.service, net.tcp.service.perf, web.page.get, web.page.perf and web.page.regexp.
Support for IPv6 addresses in Java gateway:
IPv6 addresses like 2001:db8::6c09 can now be used in JMX interfaces.
Proxy configuration size increase:
Server will include “lastlogsize” and “mtime” with every item sent to proxy. Despite these fields are used only for log file monitoring they will be currently sent with all items.
Logging IP addresses of incoming/outgoing connections between Zabbix server and Zabbix proxy:
The messages printed to the log files will now contain IP addresses of incoming/outgoing connections between Zabbix server and Zabbix proxy.
Setting DebugLevel=5 in daemon configuration file:
It is possible now to set DebugLevel=5 in server, proxy and agent configuration files. Previously it could be done using runtime control options only.
Database recovery message on DebugLevel=2:
If database query fails the following message will be printed to log file: database is down: reconnecting in 10 seconds. When database goes up database connection re-established will be printed. There were no such messages on DebugLevel=2 previously.
Macro improvements:
Low-level discovery macros can be used in item prototype IPMI sensor and Units fields.
New value maps:
Added an HTTP response code value map.
Dropped support of zabbix_agent binary:
Dropped support of Inetd version of Zabbix Agent.
Item changes/improvements:
A new proc.cpu.util item has been added to monitor process CPU utilisation. This item is supported on Linux and Solaris platforms.
A connection protocol parameter has been added to net.dns and net.dns.record agent items. The accepted values are 'udp' and 'tcp' (udp being the default).
net.dns and net.dns.record items on Windows now bypass the internal DNS resolver cache.
Improved net.if.* on Windows to get values from 64-bit counters if available.
net.tcp.listen on Linux 2.6.14 and upward kernel systems now tries to make use of the kernel's NETLINK interface.
proc.mem item now supports a 5th parameter - 'memtype' (only on AIX, FreeBSD, Linux, Solaris).
system.cpu.util now supports types 'guest' and 'guest_nice' on Linux kernels 2.6.24 and 2.6.33 and upwards, respectively.
vfs.fs.discovery item on Windows now returns an additional {#FSDRIVETYPE} macro with possible values of “unknown”, “norootdir”, “removable”, “fixed”, “remote”, “cdrom”, “ramdisk”. Note, however, that if filtering by {#FSDRIVETYPE}, low-level discovery will ignore entities discovered by older agents which return responses without this macro.
Item db.odbc.discovery was introduced to support low-level discovery using ODBC SQL queries.
A check for valid reference has been added for global regular expressions in snmptrap, log, logrt and eventlog items. If entered reference is not valid, due to misspelling or missing referenced global regular expression, the item will become unsupported and appropriate error message will be displayed.
Log file monitoring (log, logrt and eventlog) was improved by sending actual log file meta information in specific cases and keeping it on Zabbix server side. Log file meta information includes “lastlogsize”, “mtime” and “state”. Now you can safely restart Zabbix agent or remove Zabbix proxy database while monitoring a log file without getting double alerts.
vm.memory.size[available] item on AIX now returns the sum of free and cached memory. Before Zabbix 3.0 only the free memory size was returned.
vm.memory.size[available] item on Linux now reads MemAvailable (the system's native estimate) from /proc/meminfo on Linux kernels 3.14 and above. Before Zabbix 3.0 it was always the sum of free, buffers, and cached memories.
Items proc.mem and proc.num now return 0 if the specified user does not exist. Before Zabbix 3.0 these items became not supported.
Added items net.udp.service and net.udp.service.perf with the possibility to check NTP service. Before Zabbix 3.0 checking of NTP service was done using net.tcp.service and net.tcp.service.perf items. Database upgrade patches automatically convert NTP service checks.
A new service.discovery item has been added for the low-level discovery of Windows services, while the new service.info item will help retrieving information about a service. The service.info item should now be used instead of the deprecated service_state item.
vfs.fs.inode item on CephFS will become not supported instead of returning invalid numbers if second parameter is other than empty or total.
New internal checks zabbix[host,,items] and zabbix[host,,items_unsupported] were added. They return the number of items (unsupported items) on the target host.
Function improvements:
A percentile() trigger function has been added, which returns the P-th percentile of a series of values. It can be used in calculated items, trigger expressions and notifications.
A check for valid reference has been added for global regular expressions in logeventid(), regexp() and iregexp() trigger functions. If entered reference is not valid, due to misspelling or missing referenced global regular expression, the trigger will switch to unknown state and appropriate error message will be displayed.
Commandline utilities improvements:
zabbix_get exit code now is 0 (success) or 1 (error). In earlier versions it was 0 (success or error - cannot distinguish between them) or 141 (SIGPIPE).
Added printing defaults when Zabbix programs are executed with --help option.

New in Zabbix 2.3.4 (Oct 14, 2014)

Multiple filters for low level discovery:
The filter section in low level discovery rule definition has been split out into a separate tab and, most importantly, allows to define several filters as well as to define the calculation rules between the filters.
Node-based distributed monitoring removed:
Previously Zabbix supported two options for distributed monitoring - using nodes and proxies. In Zabbix 2.4.0 the support of node-based distributed monitoring has been discontinued due to existing limitations and potential problems with reliability in large environments.
While a new version of distributed monitoring may be considered and developed in the future, for the time being using proxies becomes the main distributed monitoring option in Zabbix. Furthermore, the proxy solution has proven itself over time as reliable, while also being easier in configuration and maintenance. Many users who initially had node-based distributed monitoring have switched to proxy-based setups.
One-click creation of ad-hoc graphs:
Implemented the ability to quickly display items on a graph from the latest data page.
More advanced WEB monitoring:
WEB monitoring was extended to support custom headers, configurable number of retries as well as access to SSL related options. It makes possible efficient monitoring of APIs based on XML (SOAP) and JSON protocols.
More details about unsupported agent items:
Zabbix agents now provide detailed information on why items become not supported, instead of the generic “Not supported by Zabbix Agent”.
More efficient JSON formatting:
The formatting of JSON objects (with tabs and new lines) has been removed, which allows the traffic to be reduced by 20-30% when data is sent between Zabbix services. Additionally, the escaping of forward slash or solidus (/) has also been removed.
Macro improvements:
User macros {$MACRO} now are available in notifications and commands. Two new macros - {HOST.DESCRIPTION} and {PROXY.DESCRIPTION} are supported for use in notifications and commands. {HOST.DESCRIPTION} can also be used in map labels. Host level macros - {HOST.HOST}, {HOST.NAME}, {HOST.IP}, {HOST.DNS} and {HOST.CONN} along with user macros {$MACRO} are available in simple low-level discovery rule filter regexps.
Control of SNMP bulk requests:
It is possible to control use of SNMP bulk requests per host interface.
Better syntax for trigger expressions:
Zabbix supports new operators '>=', '

Added support of monitoring of VMWare virtualization platforms including auto-discovery of VMs, monitoring of performance and availability of both VMs and hypervisors as well as nice handling of migration of virtual machines.
Loadable modules:
Added support of loadable modules for extending Zabbix agent checks, also server and proxy agentless checks.
Removed support of unknown events:
Unknown events are no longer generated and supported. New triggers will now be created in OK state.
Applications are allowed to be inherited from different templates:
Application inheritance logic was changed to allow linking multiple templates with the same applications.
Internal events:
Internal events were introduced to allow actions and notifications in case of unknown triggers or not supported items.
Automatic database upgrade:
Zabbix will automatically update database structure when upgrading to newer major version of Zabbix.
Fine grained control of housekeeper:
Housekeeper supports fine grained control on what history tables should be processes and how.

Added support of LLD macros in trigger prototype expressions, descriptions as well as in item prototypes. Added support of new notification macros: {TRIGGER.NAME.ORIG}, {ITEM.NAME.ORIG}, {ITEM.KEY.ORIG}. Updated macros {ACTION.*} and {EVENT.RECOVERY.*}; {EVENT.*} to return information of the event which triggered an action.
User permissions:
Permission logic was changed so that read permission does not override write permission anymore.
Increased maximum number of objects:
Zabbix may contain up-to 2^64-1 of different types of objects (items, triggers, events, etc) in non-DM setup.
Host prototypes:
Added support of host prototypes for low level discovery.
Zabbix API related improvements;
Zabbix API was fully documented with changelog and detailed description for all objects and methods.
Methods proxy.delete, user.delete and host.delete were changed to accept both objects and IDs. Implemented property array support for all get methods.

Added context name support, SHA authentication protocol and AES privacy protocol for SNMPv3 checks. Also added support of multiple dynamic SNMP indexes.
IPMI related improvements:
Added support of IPMI discrete sensors.
Front-end related improvements:
Regular expressions and maintenance periods form form were redesigned. Implemented multiselect in dashboard configuration, Action -> Conditions and Operations, Script, Item filter and host and host group related pages. Redesigned Host -> Templates form and added multiselect. Improved multiselect, added possibility to ignore elements. Implemented discovery rule check editing. Added possibility to add new elements in multiselect, added multiselect in hosts mass update and in items mass update form, and fixed regressions in application.massadd and in application filter. Other usability improvements.
Implemented minimum trigger severity filter in maps.
Added support of anti-aliasing for graphs and map connectors.
Added support of value mapping for character data.
Added filtering by application in Monitoring -> Overview and Data/Triggers overview screen elements.
Agent related improvements:
Added support of proc.num, net.if.in, net.if.out, net.if.total for HP-UX, system.swap.size for AIX, net.if.discovery for FreeBSD, NetBSD and OpenBSD; added printing Aliases and PerfCounters when agent is run with -p option. Added whitespace trimming for server lists in agent conf file and allowed hosts for trapper items. Added used swap size support for Windows and OSF. Added support of Windows eventlog source regex filter.
Triggers:
Increased length to 2048 characters of expression field for triggers.
Templates:
WEB scenarios can be templated.

New in Zabbix 2.0.0 RC2 (Aug 4, 2012)

New in Zabbix 2.0.0 RC1 (Aug 4, 2012)

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.
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.
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.
