10 What's new in Zabbix 7.2.5

Asynchronous DNS resolution

The agent poller and SNMP poller can now be configured to use the c-ares library (version 1.16.0 or newer) instead of the libevent DNS resolver. This allows for potentially faster and more flexible DNS resolution.

To enable c-ares, Zabbix must be configured with the --with-ares option.

Note that starting from c-ares 1.31.0, DNS caching is enabled by default.

Webhook integrations updated

The following out-of-the-box webhooks now support all event types and have been improved for code efficiency, maintainability, and functionality, with changes reflected in the documentation:

• Discord - script updated to use Discord API v10; hardcoded custom message format for trigger-based events removed.
• GitHub - GitHub API version parameter introduced to use a static version instead of the latest; in cases of escalation, existing issues are now updated instead of new ones being created; issue labels and adjustable prefixes in webhook parameters added.
• GLPi - message templates updated.
• Jira - trigger and service actions now support mapping of Zabbix event severities to Jira ticket priorities (via parameters severity_information, severity_high, etc.); support for custom Jira priorities added to all autoregistration, discovery, and internal actions (via parameters jira_priority_discovery, jira_priority_autoregistration, jira_priority_internal); Jira custom fields for ticket creation added to all actions (previously only trigger); problem event messages are now sent to the Jira ticket description, and default OK event messages are now added as comments.
• Jira Service Management (previously Jira Service Desk) - trigger and service actions now support mapping of Zabbix event severities to Jira ticket priorities; support for custom Jira priorities added to all autoregistration, discovery, and internal actions; Jira custom fields for ticket creation added to all actions (previously only trigger); support added for date and time, radio button, checkbox, single and multiple choice custom fields; URL custom field behavior adjusted; support for ticket labels added and issue name format updated to match the Jira media type; both private (default) and public comment options now available for escalations; in cases where event severity is updated between escalations, task priority no longer reverts to the original.
• MS Teams - message templates updated.
• OTRS CE - support added for closing incidents of resolved problems.
• PagerDuty - support added for closing incidents of resolved problems; API token moved to user media settings via {ALERT.SENDTO}.
