Show full answer Show less ## Key Features * **Mapping and Integration with APM Data Sources:** Yokohama introduces the ability to create and manage mappings between CMDB Workspace services and connected application performance monitoring (APM) tools, including Dynatrace, New Relic, and starting from version 1.7.3, Datadog. This enables visibility into metrics from deep system entities such as databases and hosts, enhancing service health insights. * **Service Health Visibility:** The new Overview tab displays rate, error, and duration (RED) metrics from APM data, alongside related open alerts, incidents, and change requests from the CMDB to aid in root cause analysis and blast radius assessment. * **Extended Observability Metrics:** The Observability tab provides detailed health metrics and host/database metrics associated with services based on configured mappings, offering deeper diagnostic capabilities when issues are detected. * **Dashboard Customization and Domain Separation:** Since version 1.6.4, customers can customize dashboard templates for both Overview and Observability tabs and run Service Observability in separate domains for enhanced organizational control. * **Enhanced ServiceNow Workspace (SOW) Integration:** The Service Details page now includes both Service Reliability Management (SRM) and Service Observability metrics, consolidating reliability and observability information in one interface. * **Admin Center Enhancements:** Service Observability configuration and activation can now be managed by the Service Observability admin role directly in the Admin Center without requiring a system administrator, simplifying setup and management. * **Service Activation Simplification:** From version 1.6.4, there is no need to explicitly activate services; all supported CMDB service types are usable out of the box. ## Upgrade and Activation Considerations * **Pre- and Post-Upgrade Tasks:** Customers should review and complete any necessary tasks before and after upgrading to Yokohama to ensure a smooth transition. * **Installation:** Service Observability must be requested and installed from the ServiceNow Store. The Store also provides cumulative release notes and version history for reference. * **Additional Requirements:** For optimal functionality, an APM instance (Datadog, Dynatrace, or New Relic) should be installed and configured with an API key credential on the ServiceNow platform. ## Changes and Removals * No features or functionality were removed or deprecated between Xanadu and Yokohama releases. * The introduction of new tabs and admin capabilities marks significant enhancements but no backward-incompatible removals. ## Benefits for ServiceNow Customers * Connect operational teams and subject matter experts using critical signals from existing monitoring tools and ServiceNow, centralizing key observability data. * Increase agility and reliability by bridging workflows between monitoring and ITSM processes. * Calculate blast radius and reduce mean time to resolution (MTTR) by correlating changes across applications and infrastructure.
