Frontend Value mapping on template/host level Value mapping is now configured on template/host level, in the template and host configuration forms respectively. Global value mapping has been removed Value mapping • Item list can be searched for the value map used See also: Value mapping Value mapping by range, regular expression Previously only exact matches could be used in value mapping. In the ranges, a regular expression, as well as set a default value for unmatched values. See also: Value mapping configuration Negated filtering by tags In several frontend filters it is now possible to filter

Tag-based mapping of services to problems The availability of services in previous Zabbix versions depended on triggers and their states. In the new version that is replaced by a tag-based mapping to problems sending a message to the specified recipients and executing a remote command on Zabbix server. Similarly to trigger actions, service actions support problem escalation scenarios. New message templates execution time. • Hovering over an item’s last value will show the raw value without units or value mapping applied. • If a host is in maintenance, an orange wrench icon will be visible next to the host name

will be ”0”; otherwise, the component will exit with non-zero exit code and a corresponding error message. Warnings (e.g., in case of a deprecated parameter) will not affect successful exit code. Stream either to discard the value, set a specified value or set a specified error message. 13 It is now possible to match the error message to a regular expression. If the error matches (or does not match) it is is possible to specify how the error case should be processed. For example, a specific error message can be ”mapped” to a more general case to be matched for and handled by a further preprocessing step

notification recipients, now you can also filter records by actions, media types, status, or by the message/remote command content. These filtering options can also be configured for the Action log widget commands. 24 media - a means of delivering notifications; delivery channel. notification - a message about some event sent to a user via the chosen media channel. remote command - a pre-defined command case Zabbix provides mutexes for locking in OpenSSL. If a mutex lock or unlock fails then an error message is printed to the standard error stream (STDERR) and Agent 2 exits with return code 2 or 3, respectively

ap_log_cerror has been added to log errors that occur with the client's connection. When logged, the message includes the client IP address. Test Configuration Hook Added A new hook, test_config has been it will write a message describing the problem either to the console or to the ErrorLog before exiting. One of the most common error messages is "Unable to bind to Port ...". This message is usually caused complexity of actively ensuring the cachability of URLs, mod_file_cache offers file-handle and memory-mapping tricks to keep a cache of files as they were when Apache was last started. As such, mod_file_cache

to return HMAC hash: • hmac('',key,string) This is useful for cases when hash-based message authentication code (HMAC) is required for signing requests. MD5 and SHA256 hash types are supported and the Delete missing option for the specific entity is marked. Due to this change, the warning message when marking the Delete missing option for template linkage will no longer be displayed. Query separate remote commands. media - a means of delivering notifications; delivery channel. notification - a message about some event sent to a user via the chosen media channel. remote command - a pre-defined command

NAME} macro • Problem notifications have been made more distinct from recovery notifications in the message subject 7 Item value preprocessing When it comes to preprocessing item values before storing them days to 1 day. • Maximum error message length has been increased from 128 to 2048 symbols for trigger and alert errors. This should reduce the possibility of error message being trimmed. Error messages thread crashes Previously, in case of a Zabbix agent metric thread crash only a one-line error message was logged. Now additional information including the program counter, register, stack frame (only
