followed by a Select popup for host group selection • there is also a new option to search for graph name pattern: Top-of-the-page selection dropdowns before Zabbix 5.0. 12 Multi-select fields in trigger/data overview pages and widgets Please see individual pages for details on changed host/host group/graph/etc selection: • Monitoring: – Dashboard (host selection with dynamic widgets) – Host graphs – and prototype name. IPMI sensor discovery A new ipmi.get IPMI item has been added that returns a JSON with IPMI-sensor related information. This item can be used for the discovery of IPMI sensors. Item

Zabbix API - Zabbix API allows you to use the JSON RPC protocol to create, update and fetch Zabbix objects evaluating data. Prototypes of some other Zabbix entities are also in use in low-level discovery - graph prototypes, host prototypes, host group prototypes, application prototypes. agent autoregistration

Graph widget The vector graph widget has been improved and it is now possible to: • display stacked graph (with filled areas) • add a list of items • clone

graphs as bars, the new version also introduces the possibility of creating data aggregations in a graph. So you can select the desired period (5 minutes, an hour, a day) and then display an aggregated data for some period: 8 Aggregation can be 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 versions, the new item is capable of returning values from multiple rows and columns, formatted as JSON. 10 Thus it may be used as a master item gathering all required metrics in one system call.

For compatibility where ”value” is either: • auto - connect using JSON protocol, fall back and retry with plaintext protocol (default); • json - connect using JSON protocol key; • plaintext - connect using plaintext

This step may be used in low-level discovery of SNMP OIDs. The walk[] item returns to Zabbix agent/agent 2: • system.sw.packages.get - return information about installed packages in JSON format. In comparison to the existing system.sw.packages item, the new item returns more details.

See also: Additional JavaScript objects. XML to JSON preprocessing option New option XML to JSON has been added in item preprocessing and These filtering changes are implemented in: • Monitoring: – Problem-related dashboard widgets (Graph, Problem hosts, Problems, Problems by severity) – Problems – Hosts • Configuration: – Templates

message. Extracting an error message provided in incoming data is another new feature. For example, a JSON object may contain a field ”error”. If the field exists preprocessing is able to extract its value option has been added to the following preprocessing steps: • Regular expression • XML XPath • JSON Path • Custom multiplier • Simple change • Change per second 9 • Boolean to decimal • Octal • Does not match regular expression (new validation option) • Prometheus pattern • Prometheus to JSON If you mark the Custom on fail checkbox, the item will not become unsupported in case of a failed

following developments have been made: • A new more versatile SVG-based graph widget has been added, while the classic design graph widget is also still available • Widgets no longer contain a footer displaying recovery operations and update operations have been changed to reflect the updated macros New graph widget A new graph widget for the dashboards has been introduced providing a more modern and versatile way drawing approach. For more information see dashboard widgets. The graph widget supported before can still be used and is now renamed to Graph (classic). Time selector redesign The time period selector has
