extended with new SMTP authentication options. It is also possible now to specify the server port other than the hardcoded 25 before. 9 See e-mail configuration for more details. 5.5 Item checking at specific linked to the applications created based on application prototypes. 5.12 Graph improvements 5.12.1 Better zoom In previous versions the shortest period you could zoom into was one hour. Now this limit has 12.3 Miscellaneous • ISO date format of yyyy-mm-dd hh:mm:ss used Several improvements focus on better readability of labels in graphs, especially large graphs showing data for several years: • A change

discovered that are related to different applications, you may want to see them resolved separately rather than all together. This is now possible. For example, in log monitoring you encounter lines similar to server will skip polling discovery, history and auto-registration data from that proxy. Apart from better messages processing of historical data from proxies and active agents is not affected. Log file for auto registration. • OpenSSL 1.1.0 support, it brings some new ciphersuites for PSK, enabling Perfect Forward Secrecy. See differences between OpenSSL 1.0.2c and 1.1.0 Ciphersuites • Item creation/update

Note that passwords longer than 72 characters will be truncated. Using HTTP proxy in webhooks It is now possible to specify an problem update operations: • The problem name is displayed (or N problems selected if there is more than one problem) • Size of the problem update message has been increased from 256 to 2048 characters

agent are run on the same machine it is recommended to use a different user for running the server than for running the agent. Otherwise, if both are run as the same user, the agent can access the server multiple threads, controlled by the START_POLLERS option. On the server side, if a connection takes more than Timeout seconds, it will be terminated, but Java gateway might still be busy retrieving value from intervals) and send them to the Java gateway in a single connection for better performance. It is suggested to have StartJavaPollers less than or equal to START_POLLERS, otherwise there might be situations when

proc.mem have been updated to use the latest functions intro- duced in Go 1.16 and thus provide better performance. Go version 1.16 or newer is now required for compiling Zabbix agent 2 to ensure correct restoring of more detailed state of the log*[] item in Zabbix agent memory when the agent is started than available from Zabbix server. It was developed for using in Unix environments with mirrored disks Zabbix agent is often stopped/started the new parameter can be also useful on simple filesystems for better protection against analyzing the same records twice or skipping records. Read the persistent files

widget the message ”N of M problems are shown” will still be displayed if there are more problems than can be displayed according to the Show lines setting – Digital clock will no longer be displayed new version, any unit can be prevented from being converted by using a ! prefix, for example !B. To better illustrate how this conversion works with and without the blacklisting, see the following examples everywhere in the frontend: New Old Equals =, Equal, Exactly Does not equal <> Is greater than or equals >= Is less than or equals <= Contains Like Does not contain Not like Renamed widgets, screen elements

exported). Note that the export protocol has changed with host name information now an object, rather than a string/array. Value types included in real-time export Value types are now included in the real-time Previously all triggers in host/template export were listed after the host information. Now, to achieve better readability, triggers that are based on one host item only in problem and recovery expression are usability • The widget editing experience has been improved. Several fixes have been made related to better widget focusing while in the edit mode, more usable widget resizing and repositioning. • The last

still require defining relative thresholds (e.g. check that web traffic in September, 2021 is less than 2x higher compared to September, 2020). There are use cases when such thresholds are hard to define from the remainder sequence is N times greater than the standard or mean deviation. String functions String function concat now allows concatenating more than two parameters. It can be used to combine strings triggers with the specified tag name will be included; • TrapTimer - if set, Zabbix will send no more than one trap of the highest severity in the given time frame.

0-3600 range). Active checks are considered unavailable when the active check heartbeat is older than 2 x HeartbeatFrequency seconds. Attention: This functionality will only work if the latest version agent are run on the same machine it is recommended to use a different user for running the server than for running the agent. Otherwise, if both are run as the same user, the agent can access the server previously active node. The active node monitors its own database connectivity - if it is lost for more than failover delay-5 seconds, it must stop all processing and switch to standby mode. The active node

the logged return values of executing metric threads have been changed from numeric to string for better readability. 17 Item changes/improvements A new vfs.dir.size agent item has been added to monitor was hard-coded and based on dashboard ID=1. • The height of a dashboard widget now can be no less than two rows so as to be able to display at least some content. • A new ZBX_URI_VALID_SCHEMES constant parameters and system.run items. These checks will not to become unsupported if the exit code is different than zero. Exit code checks are now only performed in custom alert scripts, remote commands and user scripts
