3 User groups


User groups allow to group users both for organizational purposes and for assigning permissions to data. Permissions to monitoring data of host groups are assigned to user groups, not individual users.

It may often make sense to separate what information is available for one group of users and what - for another. This can be accomplished by grouping users and then assigning varied permissions to host groups.

A user can belong to any amount of groups.


To configure a user group:

  • Go to Administration → User groups
  • Click on Create user group (or on the group name to edit an existing group)
  • Edit group attributes in the form

The User group tab contains general group attributes:

Parameter Description
Group name Unique group name.
Users The In group block contains a listing of the members of this group.
To add users to the group select them in the Other groups block and click on <<.
Frontend access How the users of the group are authenticated.
System default - use default authentication
Internal - use Zabbix authentication. Ignored if HTTP authentication is set
Disabled - access to Zabbix GUI is forbidden
Enabled Status of user group and group members.
Checked - user group and users are enabled
Unchecked - user group and users are disabled
Debug mode Mark this checkbox to activate debug mode for the users.

The Permissions tab allows you to specify user group access to host group (and thereby host) data:

Current permissions to host groups are displayed in the Permissions block.

If current permissions of the host group are inherited by all nested host groups, that is indicated by the including subgroups text in the parenthesis after the host group name.

You may change the level of access to a host group:

  • Read-write - read-write access to a host group;
  • Read - read-only access to a host group;
  • Deny - access to a host group denied;
  • None - no permissions are set.

Use the selection field below to select host groups and the level of access to them (note that selecting None will remove host group from the list if the group is already in the list). If you wish to include nested host groups, mark the Include subgroups checkbox. This field is auto-complete so starting to type the name of a host group will offer a dropdown of matching groups. If you wish to see all host groups, click on Select.

Note that it is possible for Zabbix Super Admin users in host group configuration to enforce the same level of permissions to the nested host groups as the parent host group.

Host access from several user groups

A user may belong to any number of user groups. These groups may have different access permissions to hosts.

Therefore, it is important to know what hosts an unprivileged user will be able to access as a result. For example, let us consider how access to host X (in Hostgroup 1) will be affected in various situations for a user who is in user groups A and B.

  • If Group A has only Read access to Hostgroup 1, but Group B Read-write access to Hostgroup 1, the user will get Read-write access to 'X'.

“Read-write” permissions have precedence over “Read” permissions starting with Zabbix 2.2.

  • In the same scenario as above, if 'X' is simultaneously also in Hostgroup 2 that is denied to Group A or B, access to 'X' will be unavailable, despite a Read-write access to Hostgroup 1.
  • If Group A has no permissions defined and Group B has a Read-write access to Hostgroup 1, the user will get Read-write access to 'X'.
  • If Group A has Deny access to Hostgroup 1 and Group B has a Read-write access to Hostgroup 1, the user will get access to 'X' denied.

Other details

  • An Admin level user with Read-write access to a host will not be able to link/unlink templates, if he has no access to the Templates group. With Read access to Templates group he will be able to link/unlink templates to the host, however, will not see any templates in the template list and will not be able to operate with templates in other places.
  • An Admin level user with Read access to a host will not see the host in the configuration section host list; however, the host triggers will be accessible in IT service configuration.
  • Any non-Zabbix Super Admin user (including 'guest') can see network maps as long as the map is empty or has only images. When hosts, host groups or triggers are added to the map, permissions are respected. The same applies to screens and slideshows as well. The users, regardless of permissions, will see any objects that are not directly or indirectly linked to hosts.
  • Zabbix server will not send notifications to users defined as action operation recipients if access to the concerned host is explicitly "denied" or if there are no rights defined to the host.
