CMDB groups

A CMDB group is a collection of CIs that lets you apply CI actions collectively to all the CIs that are members in the group.

For example, a CMDB CI Lifecycle Management API can use a CMDB group scriptable API to retrieve the group's list of CIs, and then apply a CI Lifecycle Management action collectively to all the CIs. You can also use a CMDB group with the Dynamic CI Group service population method, to populate an application service.

Group types

You can configure a CMDB group with one of the following group types:

Default

Basic group type which you can populate by manually adding CIs, saved queries, and encoded queries.

Health

Sets CMDB Health to monitor the health of the group CIs and aggregate health results for the group as a whole in the CMDB group view dashboard. For example, you can monitor health only for CIs in a specific location.

You can populate this type of group only by encoded queries. Dynamic filters are not supported when populating this type of CMDB groups.

CMDB Workspace

Custom class group which is used as follows:

• Appears in the Management view in the CMDB Workspace store app.

• Used in the Search and Explore view in the Service Graph Workspace store app. When the Service Graph Workspace - Content store app isn't installed, then CMDB group definitions in which type is CMDB Workspace, are used to structure the navigation panel in the Explore tab.

  For more information, see Explore and Search view in Service Graph Workspace.

Can be populated only by encoded queries.

Create and populate a CMDB group

Depending on the group type, you can populate a CMDB group by manually adding individual CIs, selecting saved CMDB queries, or building encoded queries in the CMDB group itself. The resulting CIs from each query are added as members to the group.

Roles required:

• To view CMDB groups: sn_cmdb_editor or itil
• To use in CMDB queries: cmdb_query_builder on top of sn_cmdb_editor or itil
• To manually add CIs: asset or sn_cmdb_editor

Also, to populate a CMDB group using a CMDB query, a saved CMDB query must exist.

The system property glide.cmdb.group.max_ci_limit determines the maximum number of CIs that a CMDB group can contain (by default 10,000). Once the specified limit is reached, CIs can't be added to the group unless you increase the value of that property.

      Dynamic filters aren't supported for CMDB health-type groups, even though it's possible to add them in a condition clause.

      Field	Description
      Class	Class for which the encoded query applies to.
      CI Overview Condition	Filter that is used in the calculation for the CI Overview chart in CMDB Workspace. Applies only if the sn_cmdb_ws.ci_overview.enable_simple_condition system property is set to true (false by default). Improves performance by yielding less results when there is a large amount of data in an environment that hasn't migrated to CSDM. This condition isn't used when selecting Show All CI.
      Condition	Filters the CIs that are included in the group. Used if CI Overview Condition isn't applicable.

   3. Select Submit.

If the CMDB group is based on a CMDB query, then the query runs in real-time and displays the resulting CIs. If the query does not complete successfully due to timing out or for other reasons, then appropriate error messages are displayed.
