host.update

Description

object host.update(object/array hosts)

This method allows to update existing hosts.

This method is only available to Admin and Super admin user types. Permissions to call the method can be revoked in user role settings. See User roles for more information.

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.

Note, however, that updating the host technical name will also update the host's visible name (if not given or empty) by the host's technical name value.

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.
All host groups that are not listed in the request will be unlinked.

The host groups must have only the groupid property defined.
interfaces object/array Host interfaces to replace the current host interfaces.
All interfaces that are not listed in the request will be removed.
tags object/array Host tags to replace the current host tags.
All tags that are not listed in the request will be removed.
inventory object Host inventory properties.
macros object/array User macros to replace the current user macros.
All macros that are not listed in the request will be removed.
templates object/array Templates to replace the currently linked templates.
All templates that are not listed in the request will be only unlinked.

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

The templates must have only the templateid property defined.

As opposed to the Zabbix frontend, when name (visible host name) is the same as host (technical host name), updating host via API 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.
