Splunk® Enterprise

Developing Views and Apps for Splunk Web

Splunk Enterprise version 9.0 will no longer be supported as of June 14, 2024. See the Splunk Software Support Policy for details. For information about upgrading to a supported version, see How to upgrade Splunk Enterprise.

API updates and migration advice

The custom visualizations API has been updated for the latest Splunk Enterprise software version.

If you used one of the previous versions of the API to build a custom visualization app, review the following versioned changes for details and migration requirements.

Changes to existing functionality require migration to support compatibility with the custom visualizations framework. Other updates add new functionality and migration is optional.

The Splunk Custom Visualization API does not support the base (search id="baseSearch" or post-process (search base="baseSearch") searches. Change these searches to inline searches to make them compatible. For more information see Overview of search types and uses in the Splunk Dashboards and Visualizations Manual.

Backwards compatibility

App code migrated to the newest API version is no longer compatible with the previous Splunk Enterprise software version. For published apps, use versioning to support separate compatibility with different Splunk Enterprise versions.


Migrating to 6.6

Changes to existing functionality

Software version 6.6 introduces a drilldown editor user interface for visualizations saved to dashboards.

The drilldown editor is available in dashboard edit mode. As of software version 6.6, the visualization Format menu no longer includes drilldown enablement and configuration settings for Splunk platform visualizations.

After saving a visualization to a dashboard, users can use the drilldown editor or Simple XML to configure drilldown behavior.

supports_drilldown

Support flag for drilldown editor availability in visualizations.conf
A new UI editor is available in Splunk Enterprise 6.6. This flag determines whether the editor is available for a visualization. Previous drilldown default behavior and configuration options in the Format menu might have changed. Remove any existing drilldown configuration options in the Format menu. Add the supports_drilldown flag to visualizations.conf and set it to true to provide the drilldown editor option in dashboards.
display.visualizations.custom.drilldown
