If any entity type on the Kubernetes entities page is configured to require a filter to display data, the Kubernetes overview page now automatically requires a filter to display data.

This configuration prevents low responsiveness on both pages when they exceed the maximum number of metric time series (MTS) processed in a signal. See Configure a Kubernetes entity type to require a filter to display data.

The Metric Explorer enhances the Metric Finder UI by letting you search and explore metrics by entity or metric name.

The tool also supports filtering by dimensions and population percentage to assess monitoring coverage before creating charts or detectors. See Search and explore data with the Metric Explorer.

Related Content between Infrastructure Monitoring and Application Performance Monitoring now auto-populates on APM views for all OpenTelemetry users.

Configuring the SignalFx exporter in the Splunk Distribution of the OpenTelemetry Collector is no longer required to enable Related Content on APM views. No action is required if you previously enabled Related Content using the SignalFx exporter.

You can use Related Content to understand correlations between data and navigate between different monitoring views. To enable Related Content between APM and Infrastructure Monitoring, see Enable Splunk APM to Infrastructure Monitoring correlation and Configure the Collector to enable Related Content for Infra and APM.

Monitor runtime metrics for Java and .NET service instances in the service view. See View instances related to your service.

Create a business transaction rule that excludes traces from being grouped as business transactions. See Configure business transaction rules.

The Queries tab now includes a Stored Procedures subtab which displays the reusable, named database objects of type "procedure". This tab is only available for Oracle Database and Microsoft SQL Server. See Queries.

Drag-select a region on most charts and then select Zoom in.

On each database platform instance navigator, see alerts associated with that instance.

Splunk RUM Android agent 2.3.0 includes the following updates:

• The navigation detection module supports activating manual and automatic instrumentation at the same time to track both built-in and custom events. See Track navigation events automatically and Track navigation events manually.

• The navigation detection module supports Jetpack Compose navigation tracking and a new NavigationEventProcessor, which transforms or suppresses Jetpack Compose navigation events before emission. See Jetpack Compose navigation tracking and Navigation event processor.

• The new activity/fragment lifecycle module records activity and fragment lifecycle transitions and sends them as RUM lifecycle telemetry. This module is activated by default. See Activity/fragment lifecycle monitoring module and the data model.

Manage your RUM Monitoring MetricSets (MMS) and Troubleshooting MetricSets (TMS) with the following enhancements to the APM & RUM MetricSets page:

• View, pause, or edit default RUM MMS.

• Edit custom RUM MMS.

• Understand the cardinality of your RUM MMS and TMS with the Unique URL and App coverage columns.

See Manage RUM MetricSets.

In this release, all but 4 page-level Monitoring MetricSets (MMS) dimensions have been deactivated by default for new users. See Default Monitoring MetricSet dimensions.

For existing users, all page-level MMS dimensions have been deactivated except for the page-level MMS dimensions used in charts and detectors.

Splunk RUM URL grouping rules version 2 is now available. See Write rules for URL grouping.

• Splunk RUM Flutter agent

• Splunk RUM React Native agent

• Android metrics

• iOS Metrics

This release introduces active runtime attack detection alongside our existing vulnerability monitoring, allowing engineering and SRE teams to identify live threats and prioritize real risks. By leveraging your existing Splunk Distribution of OpenTelemetry, Secure Application delivers these insights with minimal friction, requiring no new security agents to deploy or manage. For key features see Introduction to Splunk Secure Application.
