Map your application services using tags in the Service Mapping Workspace

 

Categorize and organize organization's configuration items and map them into application services using the Tag-based dashboard in the Service Mapping workspace.

Before you begin

• Verify that you have installed Service Mapping Plus version 1.16.3, which is required to access tag-based mapping in the Service Mapping workspace. For more information, see Install Service Mapping Plus.
• Review and analyze your organization’s tag usage, making a list of all tags and their purposes. Use the Key Value [cmdb_key_value] table to see the tags in the Configuration Management Database (CMDB).
• Use Tag Governance to optimize tag application in your organization. See Tag Governance for more information.
• Assign tags to configuration items (CIs) that you want to include in application services.
• Run Discovery to horizontally discover CIs. Discovery populates the CMDB with the CI data, including tags. For more information about discovery tag-based discovery for the Service Mapping workspace, see Tag-based discovery for the Service Mapping Workspace.

Role required: service_mapping_admin

 

Procedure

1. Navigate to Workspaces > Service Mapping, then select the Tag-based Service Mapping icon  from the navigation pane.
2. Select Create service maps.
3. Either select an existing tag category or create a new tag category.

Tag category option	Action
Select an existing tag category	Start entering the category name in the search field. Select the tag category from the list. Select Define the tag values and enter values for the selected category.
Create a new tag category	Create a new tag category by selecting Create a new tag category. Enter the tag category name. Enter values for the tag keys in the Tags field.

4. Save the tag category and values by selecting Save.

Note: To save the tag categories in a service family so you can return later to complete the mapping process, select Save and exit at any time.

5. Search for potential services matching the tag categories by selecting Find candidates.
6. Review the list of tag-based service candidates by selecting Map selected candidates when you have chosen your preferred candidates.
7. When prompted, enter a unique name for the tag-based service family.
8. Select Save and map.

Result

A tag-based application service and tag-based service family have been created.

 

 

Service Mapping Workspace

 

The Service Mapping workspace provides a central location to streamline the process of mapping your application services. Use the visualizations and reports to analyze, monitor, and update your resources, create application services, and manage your service mapping tasks efficiently.

Access

Navigate to Workspaces > Service Mapping.

Key features and capabilities

• Machine Learning (ML) readiness - Confirm that your Machine Learning environment is prepared before you start to map application services.
• Detailed service maps - Drill down for detailed information on service maps across various categories.
• Automated Service Suggestions - Leverage Automated Service Suggestions to evaluate suggested application service candidates, using them to create application services or enhance existing ones.
• Improved resource utilization - Use unmapped servers linked to an application service candidate to create application services.
• Tag-based service mapping - Use the Tag-based mapping dashboard to map your organization's configuration items (CIs) into application services.

Important:

Access to tag-based service mapping in the Service Mapping workspace requires the installation of Service Mapping Plus version 1.16.3. For more information, see Install Service Mapping Plus.

Key Metrics

Mapped application services

The number of application services previously mapped. Select to view specific information about these services such as operational status and business criticality.

ML-powered candidates

The number of application service candidates identified using the Automated Service Suggestions feature.

Note: Starting with Service Mapping Plus version 1.16.3, the filtering process has been updated to include only the most relevant candidates, excluding any ignored or irrelevant ones. This enhancement requires the installation of ITOM Content Service.

Mapped servers

The number of servers currently linked to an application service. Select to view information such as operational status and owner.

Reports

Select the relevant section of each report to view more detailed information.

Title	Type	Source table	Description
Service maps by operation type	Bar report	Mapped Application Service [cmdb_ci_service_discovered]	A bar report that presents the mapped application services grouped by operation type.
Service maps by creation method	Pie report	Mapped Application Service [cmdb_ci_service_discovered]	A pie report that presents the mapped application services grouped by creation method.
Service maps by criticality	Bar report	Mapped Application Service [cmdb_ci_service_discovered]	A bar report that presents the mapped application services grouped by the level of criticality.
Unmapped servers Note: This view is applicable to users with Service Mapping Plus versions earlier than 1.16.3.	Bar report	Server [cmdb_ci_server] Service Configuration Item Association [svc_ci_assoc] Application service candidate [sa_ml_application_service_candidate]	A bar report that presents unmapped servers that have been matched to an application service candidate as well as those servers with no candidate. Select Unmapped servers with candidate to view servers you can use to create an application service. For more information, see Create an application service for unmapped servers.
Unmapped servers Note: This view is available starting with Service Mapping Plus version 1.16.3.	Bar report	Server [cmdb_ci_server] Service Configuration Item Association [svc_ci_assoc] Application service candidate [sa_ml_application_service_candidate]	A bar report that presents the number of unmapped servers, divided into two categories: Unmapped servers without candidate - servers that have been matched to an application service candidate. Unmapped servers with relevant candidate - servers that have no candidate. Note: Starting with Service Mapping Plus version 1.16.3, the filtering process has been updated to include only the most relevant candidates, excluding any ignored or irrelevant ones. This enhancement requires the installation of ITOM Content Service.

Additional components

Populate data

You can select this button to refresh the page and update the displayed information to reflect the most recent data.

Search for server

You can locate a specific server using this field by entering the server name to see a list of options. Selecting the server you want from the list, and then Search, takes you to the Mapped Server page. Select the server name for more detailed information.

Tag-based service mapping

Select the Tag-based service mapping icon  to access the Tag-based service mapping dashboard. Here you can categorize and map your organizaton's on-prem and cloud resources into application services. For more information, see Tag-based mapping in the Service Mapping Workspace.

Application service readiness dashboard

Select the Application service readiness icon  to access the Application service readiness dashboard.

Use this dashboard to ensure you have enabled Predictive Intelligence, verify Machine Learning readiness, and confirm that your data has been trained.

For more information about application readiness, see Application service readiness dashboard in configurable workspace.
