What is a group?
The Group feature in OpManager helps the admin group devices or interfaces together for organized network management and to push bulk configurations easily throughout the product. Groups and subgroups can be used as a filter in Reports, Widget, Notification Profile, URL Templates, Downtime schedule, Alarm suppression, Device template, Interface template, Test credentials and Workflow. Groups are useful to view the average availability distribution of all the members in a group, automatically add members to a group on discovery and to configure threshold for a group of interfaces irrespective of the interface type.
What is a subgroup?
OpManager allows you to create subgroups within a group. Subgroups make bulk configuration and filtering of devices much more easier. You can create multiple subgroups and associate it with a parent group.
Consider two device groups - "Routers of model A" and "Routers of model B" in an organization. They can be collectively grouped under a parent group called "Routers".
Similarly two device groups - "Central Servers" and "Production servers" can be created and placed under a parent group called "Servers".
The two parent groups - "Routers" and "Servers" can be placed under a group "Network devices in India", which now becomes the parent group.
In Reports/Widgets, when "Network devices in India" group is selected, OpManager provides a detailed report of all the devices under the subgroups present under the parent group - "Network devices in India".
Similarly the subgroup feature can be used in any module where grouping is supported.
