Functions Functions for Prometheus histograms It has been possible to collect Prometheus metrics in Zabbix for analyze the collected data without specialized functions. To cover this functionality gap in the new version, rate() and histogram_quantile() functions, producing the same result as their PromQL counterparts

extract. For these purposes, the new version comes with a new concept of macro functions. Currently, two macro functions are supported: • regsub - substring extraction by a regular expression match (case • iregsub - substring extraction by a regular expression match (case insensitive) These macro functions are supported for the {ITEM.VALUE} and {ITEM.LASTVALUE} macro values in trigger names, trigger descrip- virtual machine 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.

regular items and item prototypes. Substring extraction of low-level discovery macro value Macro functions are now supported with low-level discovery macros, allowing to extract a certain part of the macro field of a trigger prototype: For more information on macro function syntax, see: Macro functions. Macro functions are supported in all locations where low-level discovery macros can be used, except for value. Triggers Time triggers processed by history syncers The processing of time-based trigger functions such as nodata(), date(), dayofmonth(), dayofweek(), time() and now() has been moved from timer

filter allowing to view triggers of more than one host, greatly increasing the usability of such functions as mass update. Also, the dropdowns of host and host group selection have been removed as these maintenance. JSONPath preprocessing Quoted numeric values are now accepted by the JSONPath aggregate functions (sum, min, max, etc.) in item value preprocessing. It means that the values are converted from (default is /usr/local/etc/zabbix_server.conf) -R --runtime-control perform administrative functions -h --help give this help -V --version display version number Note: Runtime control is not supported

MIB names are supported as parameters; thus walk[1.3.6.1.2.1.2.2.1.2] and walk[ifDescr] will return the same output. If several several OIDs/MIBs are specified, i.e. walk[ifDescr,ifType,ifPhysAddress], then the output is a concatenated list. This item uses GetBulk requests with SNMPv2 and v3 interfaces and GetNext for SNMPv1 interfaces;

for value preprocessing have been added: • Regular expression - find match by a regular expression/output template; • XML XPath - extract value or fragment from XML data using XPath; 11 • JSON Path - (default is /usr/local/etc/zabbix_server.conf) -R --runtime-control perform administrative functions -h --help give this help -V --version display version number Note: Runtime control is not supported --runtime-control Perform administrative functions.
