sensors. Zabbix 2.2.0 adds reading states of IPMI discrete sensors. A new function band() (bitwise AND) and an improved function count() can be used for testing state of bits of discrete sensors. 5.4 5.9 Some trigger function parameters can be empty A more friendly trigger expression parser allows to omit optional parameters in trigger functions. For example, trigger function ”last(#1)” can be written and become unsupported. 5.22 Trigger functions 5.22.1 Logical functions for testing bits A new function band() (bitwise AND) is now supported. For example, to test that the most and the least significant

to proxy availability, using the new second parameter, e.g.: nodata(5m,strict). In this case the function will work the same as before and fire as soon as the evaluation period (five minutes, in this case) that reported the failure. Zabbix agents are extremely efficient because of use of native system calls for gathering statistical information. Passive and active checks Zabbix agents can perform passive than the default DejaVu, PHP function imagerotate might be required. If it is missing, these fonts might be rendered incorrectly when a graph is displayed. This function is only available if PHP is compiled

template only. 5.9 Option to remove missing resources when importing When using the XML import function before, it was possible to create new elements and update those that already existed. While that If evaluation for nodata() function fails due to lack of data on the server, a more informative message is displayed. Previous vague message of Evaluation failed for function... has been expanded to include that reported the failure. Zabbix agents are extremely efficient because of use of native system calls for gathering statistical information. Passive and active checks Zabbix agents can perform passive

config helper Trigger configuration helper does not allow setting parameter in seconds for trigger function last() anymore 5.2.24 Improved search results page In the search results page, individual blocks cases • Item value macros in map labels now support multiplier suffixes (for example, ”{host:item.function(5m)}”) • In the global search results, host and template configuration links for host group results commands now • Suffixes ”KMGTsmhdw” are now supported in the second parameter of count() trigger function • Previously it was possible to send large amount of data to the Zabbix server, potentially exhausting

Doughnut chart. For more information, see Pie chart. As part of this development, a Show aggregation function checkbox has been added to the graph widget configuration (in Legend tab). Top triggers A Top given criteria. • All foreach functions no longer include unsupported items in the count. • The function last_foreach, previously configured to ignore the time period argument, accepts it as an optional expanded to match the range of double data type. Now timeleft() function can accept values up to 1.7976931348623158E+308 and forecast() function can accept values ranging from -1.7976931348623158E+308 to

be enabled per server/proxy process. Enabled profiling provides details of all rwlocks/mutexes by function name. See also: • Zabbix server runtime commands • Zabbix proxy runtime commands Date removed must not contain a trailing space). Signing data using RS256 A new sign(hash,key,data) JavaScript function has been implemented allowing to use the RS256 encryption algorithm to calculate the signature support Support for TimescaleDB version 2.11 is now available. 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

terminating runaway processes. Instead of using standard popen method as before, Zabbix now explicitly calls /bin/sh to execute desired command. • Trying to run a Zabbix daemon, compiled on Linux kernel 2.6 Entering function parameter time_shift It is now possible to enter time_shift trigger function parameter in the trigger expression helper. 48 8.1.6.2 Filtered function dropdown When choosing function to available for {ITEM.VALUE} macro in trigger notifications 8.3.3.2 New trigger functions New trigger function has been added - strlen, which returns length of the last value in characters. 8.3.3.3 Improved

event tags, notifications subjects and notification messages. For more information see the macro function section. 9 5.6 Nested representation of host groups Having a built-in mechanism for a logical discovery item keys vmware.hv.discovery and vmware.vm.discovery. 5.17 Trigger functions The count() function now supports regexp and iregexp operators for all item types. It is now possible to count values in triggers/calculated items Previously any unsupported item in trigger ex- pression or error in function evaluation immediately rendered the whole expression value to Unknown. Triggers became Unknown,

been reduced multiple times. The nodata() function calculation has been improved to limit the database requests to the range specified in nodata() function. When an active proxy connects to Zabbix server and undocumented registry keys. 24 5.22 Function improvements forecast() and timeleft() predictive functions have been added. A percentile() trigger function has been added, which returns the P-th percentile Support for suffixed values has been added to the threshold parameter of the timeleft() trigger function. • forecast() now supports negative values in the time parameter. 12 What’s new in Zabbix 3.0

configured in the data set settings when configuring a graph widget. You may pick the aggregation function and the time interval. Since a data set may comprise several items, there is also another option Additionally the expression tag of these triggers does not reference the host or item, but only the function ({last()}<>0 in the example): Host ... Item parameter has been added to the Configure() function, the format of passed plugin parameters to the Configure() function has been changed and the Validate() function has been added to validate plugin specific
