host.update

Description

object host.update(object/array hosts)

This method allows to update existing hosts.

Parameters

(object/array) Host properties to be updated.

The hostid property must be defined for each host, all other properties are optional. Only the given properties will be updated, all others will remain unchanged.

Additionally to the standard host properties, the method accepts the following parameters.

Parameter Type Description
groups object/array Host groups to replace the current host groups the host belongs to.

The host groups must have the groupid property defined.
interfaces object/array Host interfaces to replace the current host interfaces.
inventory object Host inventory properties.
macros object/array User macros to replace the current user macros.
templates object/array Templates to replace the currently linked templates. Templates that are not passed are only unlinked.

The templates must have the templateid property defined.
templates_clear object/array Templates to unlink and clear from the host.

The templates must have the templateid property defined.

As opposed to the Zabbix frontend, when name is the same as host, updating host will not automatically update name. Both properties need to be updated explicitly.

Return values

(object) Returns an object containing the IDs of the updated hosts under the hostids property.
