For more details 8 Installation • You now have the option to install, or not install, several package tasks. See Section 3.1, “Package Tasks” [p. 9] for details. Also, there is an option to launch aptitude to choose

a highly integrated network monitoring solution, offering a multiplicity of features in a single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling) user names because temporary account blocking after consecutive failed login attempts is only applied to existing user names, the account blocking is now also enforced if non-existing user names are used supported. Note that this change does not affect frontend encryption (which uses its own openssl-php package) and Java gateway JMX encrypted connections to monitoring targets (which uses its own Java encrypted

a highly integrated network monitoring solution, offering a multiplicity of features in a single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling) Specifically, the metrics of histogram type can be presented in Zabbix as multiple items with the same key names, but different parameters. However, even though such items are logically related and represent the lines) • vfs.fs.discovery and vfs.fs.get now return an {#FSLABEL} macro on Windows (with volume names) For more details see agent items. Calculated items Calculated items now support not only numeric

a highly integrated network monitoring solution, offering a multiplicity of features in a single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling) For example, walk[1.3.6.1.2.1.2.2.1.2,1.3.6.1.2.1.2.2.1.3] returns a multi-line list of interface names and types. Using the Zabbix preprocessing options, the response of this item may be used to discover OIDs. The walk[] item returns the output of the snmpwalk utility with -Oe -Ot -On parameters. 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

Data gathering • availability and performance checks • support for SNMP (both trapping and polling) TimescaleDB is not supported by Zabbix proxy. Using item value to name discovered hosts Previously names of new hosts added as a result of network discovery were using either the DNS name or, in the absence information. Macros New macros supported in maps More macros are now supported in map element labels, URL names and URL values: New supported location in maps Macros Host element Host group el- e- ment Trigger

a highly integrated network monitoring solution, offering a multiplicity of features in a single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling) in item and item prototype names User macros are now supported in item names and item prototype names. Note that user macro support was removed from item/item prototype names in Zabbix 6.0. Now it has has been added that is responsible for resolving and synchronizing the user macro values in item names. Extended support of macro functions Macro functions are now supported with all types of macros:

Data gathering • availability and performance checks • support for SNMP (both trapping and polling) ignore these properties. The new jmx.get[] item does not generate LLD macro names in the returned JSON. Instead, LLD macro names may be defined in the custom macro tab of a discovery rule, using JSONPath ’HostInterface’ or ’HostInterfaceItem’ configuration parameters are supported since Zabbix 4.4. Longer host names allowed in discovery Maximum allowed length of a host name has been lifted from 64 characters to 128

Data gathering • availability and performance checks • support for SNMP (both trapping and polling) HP-UX • AIX 5.1.1.2 Mounted filesystem discovery Mounted filesystem discovery returns filesystem names along with their types. Network interface discovery support has been added for the following platforms: endpoints are sorted by type in the dropdown 12 5.2.11 Customisable trigger severity names and colours Trigger severity names and colours can now be easily customised in Administration → General → Trigger severities
