Show full answer Show less ## Key Features * **Improved Log Streaming Performance:** The Lightning gRPC client introduced in Xanadu can increase log streaming speeds up to six times by enhancing MID Server communication with your ServiceNow instance. Activation requires manual configuration. * **Glide System Logs Streaming:** Stream system log messages directly from the Glide Syslog table to HLA's AI engine (Occultus) using a dedicated data input that operates without a MID Server. * **Integrations Launchpad Enhancements (Yokohama):** Version 36.0.19 introduces a unified interface to easily configure log data integrations for multiple sources, including Splunk TCP/UDP, Splunk Poller, MID Server, Apache Kafka, Microsoft Azure Log Analytics, REST API, and Amazon Data Firehose. * **Amazon Data Firehose Integration:** Enables real-time log data streaming from various sources into ITOM Gateway's collector service, bypassing MID Server requirements. * **Dedicated Data Inputs for High-Volume Tools:** Simplify ingestion of large log volumes by integrating with Cribl and Edge Delta tools through specific data inputs designed for these platforms. * **Splunk Data Handling:** Two new methods improve Splunk integration---polling data input for regular data pulls, facilitating consistent workflows with minimal stakeholder effort, and enhanced data input for ingesting preprocessed, structured Splunk data. * **Alert Description Generation:** Now Assist can be used to generate descriptive information for Health Log Analytics alerts, improving alert context and response. ## Key Changes * **Alert Grouping Model Updated:** The previous component-based alert grouping has been deprecated and replaced by a streamlined two-tier model that groups alerts from Log Analytics into single alerts. This enhances alert visibility and simplifies correlation by aligning alerts with service-level anomalies rather than individual hosts. * **Renaming of Data Input:** The Glide Syslog data input has been renamed to ServiceNow System Logs data input for clearer identification. ## Upgrade Preparation and Activation * **Pre- and Post-Upgrade Tasks:** Review and complete necessary upgrade tasks before moving to Yokohama to ensure a smooth transition. * **Installation:** Health Log Analytics must be requested and installed via the ServiceNow Store. This applies to both Xanadu and Yokohama releases. * **Browser and Localization:** No changes in browser requirements. Supported languages remain US English, UK English, French, German, Italian, Japanese, and Spanish, with US English as the default. ## Important Notes * No features or functionality were removed or deprecated specifically between Xanadu and Yokohama, aside from the alert grouping model change. * The Lightning gRPC client requires manual activation to achieve faster log streaming. * The Integrations Launchpad significantly simplifies log data connector management, enabling faster deployment and integration of multiple log sources. By understanding these enhancements and changes, ServiceNow customers can leverage the improved performance, integration capabilities, and streamlined alert management introduced through the upgrade to Yokohama, thereby enhancing their operational insight and efficiency in managing log data.

Note that the Lightning gRPC client requires manual configuration to activate. [Stream system logs from Glide to Health Log Analytics](https://www.servicenow.com/docs/access?context=hla-data-input-glide-syslog&family=xanadu&ft:locale=en-US) : Use the Glide Syslog data input to stream log messages from the System Log table (Glide Syslog) in Glide to the Health Log Analytics AI engine (Occultus). Note: Only a single Glide Syslog data input can exist in the system. This data input doesn't run on a MID Server. | | Yokohama | [Configure log data integrations from the Integrations Launchpad](https://www.servicenow.com/docs/access?context=hla-data-input-setup-integrations&family=yokohama&ft:locale=en-US) : Starting in version 36.0.19, benefit from additional log data integrations for Splunk TCP/UDP, Splunk Poller, MID Server, Apache Kafka, Microsoft Azure Log Analytics, and REST API that can be easily set up through the Integrations Launchpad. [Set up an Amazon Data Firehose integration for real-time log data streaming from multiple sources](https://www.servicenow.com/docs/access?context=il-connector-hla-firehose&family=yokohama&ft:locale=en-US) : Starting in version 36.0.19, leverage an integration for streaming log data from Amazon Data Firehose directly to the collector service in ITOM Gateway, where it is queued and then processed by Health Log Analytics. This integration doesn't run on a MID Server and can be configured from the Integrations Launchpad. [Integrate with log data connectors from the Integrations Launchpad](https://www.servicenow.com/docs/access?context=hla-data-input-setup-integrations&family=yokohama&ft:locale=en-US) : Take advantage of the Integrations Launchpad's unified interface for convenient integration with log data connectors that feed raw log data from external sources into your instance. You set up log data connectors for HLA from the Event Management Integrations Launchpad in Service Operations Workspace for ITOM. In this release, the Integrations Launchpad enables integration with the following connectors: Elasticsearch, ServiceNow System Logs, UDP, and TCP. [Use Cribl and Edge Delta data inputs to streamline HLA data ingestion with tools handling large log volumes](https://www.servicenow.com/docs/access?context=hla-data-input-setup-manual&family=yokohama&ft:locale=en-US) : Use dedicated data inputs to facilitate data ingestion from Cribl or Edge Delta when using these tools to handle large volumes of log data from multiple sources before sending it to HLA. [Pull data from Splunk regularly using the Splunk Polling data input](https://www.servicenow.com/docs/access?context=hla-data-input-splunk-polling&family=yokohama&ft:locale=en-US) : Make your data workflows more consistent and productive by fetching data consistently over time using the Splunk Polling data input, which sends recurring queries (polls) to Splunk. Handling most configurations on the HLA side means you need minimal additional stakeholder involvement, which enables swift integration with your existing Splunk setup. This enhancement accelerates proofs of concept (POCs) and enables faster iterations using real data. [Use your Splunk data input to ingest preprocessed data from Splunk](https://www.servicenow.com/docs/access?context=hla-data-input-splunk&family=yokohama&ft:locale=en-US) : Ingest data from Splunk in a preprocessed, structured format using your existing Splunk data input. | [ ] ## Changes Between your current release family and Yokohama, some changes were made to existing Health Log Analytics features. {#dfrn3-healthloganalytics-summary__entry__14} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | [Component-based alert grouping is deprecated](https://www.servicenow.com/docs/access?context=hla-op-log-analytics-alert-types&family=yokohama&ft:locale=en-US) : Starting in version 36.0.19, the adoption of a streamlined two-tier alert model, Log Analytics Group to Single Alert, has replaced component-based alert groups, which have been removed. This model aligns alert representation with the service-level anomalies identified by Health Log Analytics, rather than individual host CIs. The update improves alert visibility, simplifies correlation, and enhances overall alert management efficiency. [ServiceNow System Logs data input](https://www.servicenow.com/docs/access?context=hla-data-input-glide-syslog&family=yokohama&ft:locale=en-US) : The Glide Syslog data input has been renamed ServiceNow System Logs data input. | [ ] ## Removed Between your current release family and Yokohama, some Health Log Analytics features or functionality were removed. {#dfrn3-healthloganalytics-summary__entry__20} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | No updates for this release. | [ ] ## Deprecations Between your current release family and Yokohama, some Health Log Analytics features or functionality were deprecated. {#dfrn3-healthloganalytics-summary__entry__26} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | No updates for this release. | [ ] ## Activation information Review information on how to activate Health Log Analytics. {#dfrn3-healthloganalytics-summary__entry__32} | Release | Release notes | |-|-| | Xanadu | Install Health Log Analytics by requesting it from the ServiceNow Store.
