| Manual CI Inclusions / Exclusions \[svc\_manual\_ci\_exclusions\_inclusions.list\] | Contains CI classes included or excluded from application services during population of manual or dynamic application services. Service population happens when- Manually adding CIs to an application service - Converting a business service to an application service - Creating or updating an application service using APIs - Manually updating an application service with changes from the CMDB Note: The Manual CI Exclusions/Inclusions [svc_manual_ci_exclusions_inclusions] table doesn't include CIs added using traversal rules. In the base system, the following CI classes are excluded:
CIs of any CI class that is not configured for exclusion in this table can be added to application services. Note: In the CMDB hierarchy, a class derives the included/excluded setting from its closest ancestor. If a class has its own explicit setting, it overrides the derived setting. This table supports the functionality that was earlier supported using the following deprecated property: sa.mapping.user.manual.citype.blacklist. |
Properties installed
To access application services properties, navigate to All > Configuration > Application Services > Properties. The role required for modifying property values, is app_service_admin.
If Service Mapping is deployed, see Properties installed with Service Mapping for additional application service properties.
Note: To open the System Properties [sys_properties] table, enter sys_properties.list in the navigation filter.
| Property | Usage |
|---|---|
| The sys\_id of the default relation type to be added between source and target when adding CI manually to application service sa.it\_service.manual\_ci\_rel\_type | - Type: string - Default value: 5599a965c0a8010e00da3b58b113d70e \(Depends on::Used by\) - Learn more: Manually add CIs to an application service |
| Coefficient of aggregation interval. 0 value means no aggregation is performed on history timeline. The purpose of this property is to decrease number of changes in history timeline by increasing the interval allowed between changes sa.history.aggr\_interval\_coef | - Type: integer - Default value: 1 |
| Sync Service Mapping operations with Service Modeling sa.service\_modeling.use | - Type: true\|false - Default value: true |
| Enable limitation of application service maps drawing by number of nodes and edges. sa.map.LIMIT\_MAX\_GRAPH\_SIZE | Limit the number of nodes and edges on application service maps. - Type: true\|false - Default value: true Setting this property to false may reduce performance in maps of large services. |
| Maximal number of displayable nodes on application service map. Maps with larger values will not be displayed. sa.map.MAX\_NODES\_FOR\_LAYOUT | The max number of nodes displayed on an application service map. If the number of nodes exceeds the specified number, the map does not appear and an error message appears. - Type: integer - Default value: 5000 |
| Global flag to allow or disable spanning tree view for maps. true \(default\) - allows but not forces spanning tree view on maps. sa.map.ALLOW\_SPANNING\_TREE\_VIEW | Enable spanning tree view for application service maps. - Type: true\|false - Default value: true |

| Limit of amount of services that displayed on Services Tree on maps. Then this limit reached, Services Tree will be blocked. sa.service\_tree.MAX\_ITEMS\_TO\_DISPLAY | - Type: integer - Default value: 7000 |
| Maximal amount of connection properties to be shown at once when connection line selected on service map. If selected line contains more connections than defined here, then properties panel will have notification about cut-off connections. sa.map.max\_connections\_in\_properties\_panel | - Type: integer - Default value: 50 |
| Enable grouping of CIs on map. sa.map.enable\_auto\_grouping | - Type: true\|false - Default value: true |
| Minimal number of CIs on a map to apply CI grouping. Relevant only if CI grouping is enabled on the map. The following CIs are not counted: discovered clusters, internal CIs inside inclusion boxes, entry points, error nodes, host CIs or CIs that are not hosted on other CIs. sa.map.min\_nodes\_for\_auto\_grouping | - Type: integer - Default value: 10 |
| Render full labels on CIs on map. Applicable to all CI labels \(CI name, host name, cluster label, etc.\) Enabling this will disable labels truncation, and labels will most probably overlap with other map elements. Not applicable to network/storage path maps. sncCommonMap.RENDER\_FULL\_LABELS | The default value of disabled, means none.- Type: choice list - Default value: Disabled - Other possible values: - Exported PDF only: pdf - Map and PDF views: all |
| Maximal width of CI node labels in pixels. Relevant for any kind of labels \(CI name, host name, cluster label etc.\) This size also modifies horizontal space between CI elements. Applied to map view and exported PDF view. Not applicable to network/storage path maps. sncCommonMap.NODE\_LABEL\_WIDTH |
