been updated to use native SNMP bulk requests (GetBulkRequest-PDUs), available in SNMP versions 2/3. A GetBulk request in SNMP executes multiple GetNext requests and returns the result in a single response response. Previously, only the SNMP discovery[] item in Zabbix would use GetBulk requests; it was not available for regular SNMP items and also discovered SNMP items would have to query the devices independently becomes possible to collect data in one request and parse the response as needed, without additional requests to devices. 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

lines in the Windows event log based on the specified parameters. Asynchronous single-OID SNMP requests A new get[OID] SNMP item has been added allowing to query for a single OID value asynchronously automatically executed on a monitored host upon some condition. web scenario - one or several HTTP requests to check the availability of a web site. frontend - the web interface provided with Zabbix. dashboard • connector manager - manager process for connectors • connector worker - process for handling requests from the connector manager • discovery manager - manager process for discovery of devices • discovery

improvements Ability to specify custom headers It is now possible to specify custom headers for HTTP requests in web monitoring: Custom headers are available on both the web scenario and scenario step levels has been added to the web scenario configuration form. 5.7 Optional SNMP bulk requests Bulk processing of SNMP requests was first introduced in Zabbix 2.2.3. While providing benefits in terms of reduced SNMP devices, it also encountered problems with a number of devices that did not respond to these requests as expected. As a result, SNMP bulk processing has been made optional in Zabbix 2.4.0. Enabled
