New features

Between your current release family and Xanadu, new features were introduced for Health Log Analytics.


Release	Release notes
Vancouver	Use MID Server clusters for failover protection Ensure continuous log streaming by using MID Server clusters. If the MID Server that a puller data input runs on fails, its tasks are moved to the next available MID Server in the cluster. Mute unimportant alerts for all components of an Application Service Stop Health Log Analytics from generating an alert for all components of an application service by muting the alert metric. Test your data input mapping script on more log samples Expand the number of log samples used for testing your Data Input Mapping JavaScript function up to a maximum of 5,000 samples. View the outcome of your data input mapping script See the outcome of your data input mapping script on log samples, log sources, and source types on the Data Input Mapping form. Get notified on relevant pages when data has stopped streaming Display a notification on the Data Input page, the Data Input Mapping page, and the Streaming Sources page when the AI engine is down and data has stopped streaming.
Washington DC	Scale Health Log Analytics to support increased log ingestion Stream log data to Health Log Analytics in a scalable, more stable way by using the advanced ServiceNow infrastructure. The new architecture leverages queueing technology in IT Operations Management Cloud Services for authentication and log ingestion. The Health Log Analytics AI engine has been enhanced to scale dynamically in response to increased log ingestion by your organization. You can switch to the new infrastructure by submitting a scaling request through the Now Support catalog or via your ServiceNow account manager.
Xanadu	Enjoy a significantly faster log streaming rate with the Lighting gRPC client for MID Server communication with the ServiceNow instance Increase log streaming speeds to Health Log Analytics by up to six times through the Lightning gRPC client, which enhances MID Server communication with your ServiceNow instance. Note that the Lightning gRPC client requires manual configuration to activate. Stream system logs from Glide to Health Log Analytics 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.
