Adding Device Groups

Device groups are created and managed from the Devices page:

To add a device group, go to Devices Tab | Add | Group from the top of the device tree. As shown (and discussed) next, the Add Device Group dialog box displays.

Name

The name will display in the device tree and will be used as a reference in reports and dashboards.

Note: Device group names cannot include the operators and comparison functions used in datapoint expressions, as listed in Datapoint Expressions.

Note: Additionally, device group names, as best practice, should not include the following filter reserved strings: :::, :, !::, !~, ~, >:, <=, !:, >, <. Use of these strings can cause errors when filtering on device groups within dashboard widgets or other functionalities that filter according to device groups.

Description

The description of the group will be displayed on hover in the device tree.  

Enable alerts

If alerting is enabled, alerts will be generated if a threshold is exceeded by any device datapoint in the group.  Disabling alerting allows data to be collected without alert generation.  Alerts can also be disabled at the device, datasource, and datapoint level.

Auto-assign devices

Automatically assign devices to this group based on device type, device group, device name or a custom query that utilizes LogicMonitor's AppliesTo scripting language. Devices currently in your account, as well as devices added to your account in the future, will be assigned to this dynamic group if they meet the specified criteria. You will need "Manage" rights at the root level in order to create a dynamic group. 

Note: Unlike when determining DataSource associations, the criteria that dynamically determines which devices are auto-assigned to a dynamic group (i.e. the AppliesTo script) can only evaluate properties of the host itself, not any inherited properties from those groups of which it is a member. This is to avoid circular referencing. For similar reasons, the systems.group property is also excluded from use in a dynamic group's AppliesTo script as the query itself could change the results of the query, potentially creating an endless loop.

Enable Network flow analysis for this group

Selecting this box will enable collection of Netflow data on all devices assigned to this group.

Parent group

Assign a parent group if the new group will be a subgroup.

Devices and collector

Manually assign devices that will appear in this group.  Cannot be used with auto-assign devices.

Properties

Properties defined at the Group level will automatically be inhereited by group members if properties are not assigned at the subgroup or member level.
