New features and improvements in SolarWinds Platform

Feature Adoption

A new section in My Deployment that shows you how to enable and expand the usage of key features of your products.

High Availability repair

Users can run a repair on HA pools in the web console or via CLI. This resolves HA issues fast without the need to contact support. See Repair a HA pool, for more information.

Dark theme available for all modern dashboards

  See this video: SolarWinds Observability Self-Hosted 2025.4 - Dashboard Updates. /archive/sw-videos.htm?uuid=bl4yi829ey&title=SolarWinds Observability Self-Hosted 2025.4 - Dashboard Updates

Users can now switch to the dark theme without using the NOC mode. Each logged-in user can set their theme in their profile. See Dark theme for modern dashboards.

Modern dashboards

• A new modern dashboard widget, the Entity Drill-Down widget, has been introduced to group and drill down into different node and group entities. This brings functionality of the legacy All Nodes and All Groups widgets to modern dashboards. Users can simply select groupings with drop-down or different entity properties, without having to use custom query/SWQL to modify this widget.

• In KPI widgets, users can now synchronize font size when using multiple KPI tiles. The option is available when editing a KPI widget in the Scale Sync Configuration setting.

508 Compliance

Support for 508 compliance has been improved to ensure that the software is accessible to people with disabilities. The Login page and the main menu have been updated to better comply with this standard.

Recurring maintenance schedules

• Users can now specify a reason for placing entities in maintenance mode for both one-time and recurring jobs.

• Users can schedule multiple maintenance jobs for a single entity.

• Users can schedule maintenance windows for volumes.

• Users have a better visibility of upcoming maintenance windows:

  • A new Maintenance Windows widget has been added to node details pages.

  • The next maintenance window is displayed in the Node Details widget.

Intelligent Maps improvements

• Users can assign a single interface to a line.

• When users move labels, connections to shapes or entities are visible.

• Users can add or remove connection pills.

• Users can align objects in a new alignment menu with complete object alignment options.

• Users can add multiple labels for shapes.

• Users can edit line width for lines and connections.

• Users can use underlined text in text boxes and labels.

• Labels appear arranged around shape or entity instead of overlapping.

Additional updates

• Data collected by SolarWinds Platform agents during polling engine failover is now retained and stored after failover completes.

• Added support for real-time polling for Linux and AIX agents.

Fixed CVEs

At SolarWinds, we prioritize the swift resolution of CVEs to ensure the security and integrity of our software. In this release, we have successfully addressed the following CVEs.

Fixed customer issues

Case number	Description
01933770	*An issue that caused sporadic behavior when zooming in or out of some maps has been fixed.

01741880, 01939288	*A new centralized setting called LinuxFreeMemoryStrategyList allows users to define priorities for strategies that are used to calculate unused (free) memory and therefore overall memory utilization on a Linux server polled by SolarWinds Platform Agent nodes. For more information, see Advanced Options for Changing Memory Usage Calculation on Linux Agent Nodes.
01641350, 01920509	A passive agent that becomes stuck no longer prevents other passive agents from functioning correctly, which can cause nodes to be falsely reported as down.
01939127	When an HA failover occurs during an upgrade and the active main polling engine has been upgraded, the upgrade of the original main polling engine is no longer blocked.
01905733	Intelligent Maps on modern dashboards now support live updates.
01907591	When access points have an empty or null IP address API polling no longer fails for Arista Wireless Manager devices. Data for the devices is displayed, and errors such as the following are not written to the logs: Failed parse source value: for type: String
01839233	Syslog messages with more than approximately 1,500 characters are no longer truncated.
01891872, 01984074	Some Cisco devices, such as Cisco C1121-4P and Cisco FirePOWER 1140 Security Appliance, now show the model name instead of being identified as only 'Cisco'.
01839054	Recursion in Intelligent Maps is identified with the following message in the logs: Recursion: cannot add entity {entity.Id} because it's a member of {container.Id} container. However, recursion does not prevent updates to the container and the creation of valid relationships to other entities.
01829210, 01899647, 01923408, 01931362	Performance has been improved and issues that could cause the Web Console to stop responding or fail to load have been fixed.
01929172	Performance of preflight tests during Centralized Upgrades has been improved for large environments with many scalability engines. If communication issues between servers prevent the tests from completing, they timeout with a message instead of hanging.
N/A	The High Availability failover reason is now added to audit events.
00073130, 01913515	When a node belongs to more than one group, you can click Simulate or Execute to test an alert action on the node. The test no longer fails with the exception NetObjectData is null.

Installation or upgrade

Known issues

If you have SendTrustedIssuerList enabled, the Configuration wizard may fail

SolarWinds internal certification authorities are not stored in the system trusted certificate stores. When SendTrustedIssuerList is enabled, the system only allows client certificates signed by trusted certification authorities, causing the SolarWinds client certificate to be rejected.

The Configuration wizard may fail with the following message.

Failed to setup RabbitMQ for SolarWinds Platform

Resolution or workaround: Follow the instructions in the "Failed to setup RabbitMQ for SolarWinds Platform" when SendTrustedIssuerList registry key is enabled article.

Network Atlas map errors when rendered from the Custom List of All Maps widget

When you upgrade to 2025.4 and open a Network Atlas map from the Custom List of All Maps widget, an unexpected error while generating the map occurs.

Resolution or workaround: Switch the application pool from 32- to 64-bit mode. See How to Switch IIS Application Pool Between 32-bit and 64-bit Mode.
