New features and improvements in SAM

There were no features or improvements added for SAM in this release.

New features and improvements in SolarWinds Platform

Discovery Central page

  • A new Discovery Central page provides a single, modern entry point for discovering and managing monitored environments.

  • Users get an overview of what is currently monitored and can discover additional resources from a centralized location.

  • The Discovery Central page is available from the Settings menu.

What's New page

The What's New page helps administrators quickly understand new features and important changes after upgrading. This page shows once for administrators after the first login following an upgrade. Later, it is available as a tab in the new Discovery Central page.

Simplified discovery wizards

  • Discovery wizards now focus on essential configuration steps and provide links to advanced workflows for more complex scenarios.

  • New maintenance frequency options align maintenance windows with real-world business cycles.

High Availability

  • Enlarged HA Pools table for improved readability.

  • Extended hover behavior across table cells shows pool member roles.

  • Automatic selection of standby members for manual failover in 1:1 HA pools.

  • Simplified and condensed page header.

Engine load balancing

High availability deployments benefit from improved engine load balancing, distributing workloads more evenly across engines to improve performance and reliability. See Balance load on additional polling engines in an HA pool.

Expanded Windows scheduling options

Administrators now have additional scheduling options for Windows-related activities, enabling greater flexibility for recurring events.

Additional updates

  • Agent communications now support TLS 1.3, enhancing security by using the latest industry‑standard encryption protocols for data in transit.

  • Several enhancements improve the experience of editing and managing Intelligent Maps.

  • Introduced SolarWinds Message Bus Service to replace RabbitMQ.

    • This release only upgrades smaller deployments (fewer than 300 nodes, fewer than 3 polling engines, and not using High Availability).

    • Larger deployments will upgrade to SolarWinds Message Bus in a future release.

  • Added support for group Managed Service Accounts (gMSA) for authentication between the SolarWinds Platform and the SQL Server. This reduces reliance on manual service accounts and passwords. Customers can switch to gMSA authentication in the Configuration wizard.

  • Users without administrator privileges but with node management permissions can now access the Manage Agents page and manage SolarWinds Platform Agents.

  • DirectLink accounts can no longer be assigned administrator or node-management permissions.

  • Added agent support for RHEL 10.

  • Modern dashboard table widgets can now replace empty values with Unknown.

  • Added a Nodes with polling issues report. The report shows all nodes with polling issues, including the node name, assigned engine, start time, error code, and error message.

Platform
01975626, 02037128 All types of widgets can be removed from custom modern dashboards, including previously non-removable system widgets such as wireless access point components, so you can fully customize dashboard layouts. Platform
01981326, 01997101 Extra spaces at the beginning or end of custom property values are now removed before the value is saved to the database, so a value with an extra space (for example, "One ") will no longer be seen as different from that value without the extra space (for example, "One"). Platform
01961282 The performance of an AIIM cleanup query has been improved to prevent excessive CPU and memory usage. Platform
00535994, 02025253 In the Manage Nodes table, adding the Polling Engine column no longer blocks certain actions such as polling now, unmanaging, or exporting custom properties. Platform
02049659 When an item on a World Map has an incorrect instance ID value (for example, two node IDs for the same value), the map no longer fails to render, even if the system logs a clear warning. Platform
01951065 When widget settings include an entire URL with the primary web server domain, clicking that widget from an additional web server redirects to the primary web server. However, users that are logged in are no longer prompted to log in again. Platform
02030565, 02041758, 02046997, 02045991, 02045994 The installer now performs a preflight check to validate that the .NET8 versions match. Mismatched minor version numbers can cause upgrades to fail or the console to become inaccessible. Platform
01934208

When a server monitored with WinRM over HTTPS uses a self-signed certificate, the hostname is resolved to the IP address. Therefore, the PowerShell component monitor no longer fails with the following error:

The SSL certificate contains a common name (CN) that does not match the hostname.

SAM
02036053 When the Agent Management Service (AMS) is monitoring high availability pool tables, AMS no longer returns information about pools that are disabled. Platform
02041234

The WinRM/WMI SelectCommand for AppInsight now returns only the properties requested in a query instead of all properties, significantly lowering memory usage for large result sets such as IIS file statistics collection.

Platform
02049748 An issue was resolved that could cause the size of the folder containing queue files to increase significantly after an upgrade. Platform
02049748 Declarative Pipeline collector engine assignment now correctly loads entities on the appropriate polling engine when the engine assignment is defined on a parent entity rather than on the entity itself, preventing misloaded entities and related collector log errors in environments that use this configuration. Platform
02055264

Alert integrations now ensure that when SolarWinds Observability Self-Hosted is integrated with ServiceNow, alert reset status is correctly synchronized to ServiceNow, and the SolarWinds Incident Response alert action works end-to-end so you can select an SIR instance, create incidents from alerts, and track their status updates directly in the SolarWinds Platform.

Platform
02053174

If an alert configuration becomes corrupted in the database, the alerting service no longer fails with the following error:

ERROR SolarWinds.Alerting.Service.AlertingService - Unhandled exception caught by Alerting Service.

Platform

02064612

In Japanese and German environments, duplicated maps no longer show a different overall status than the original maps, even though they contain the same objects.

Platform
02043659

Network discovery deduplication controls now correctly honor the configuration that disables specific deduplication checks, allowing administrators to discover all intended nodes even when IP, MAC, or other deduplication rules are turned off.

Platform
02057090

When you add a Windows node using WMI and WinRM as the polling method, and then you turn off WinRM, attempting to reboot it from the node details page no longer fails.

SAM
02077323

Toolbar search fields now allow left and right arrow key movement inside the search box on affected pages, so you can move the text cursor with the keyboard as expected.

Platform
02071573

When a bulk update of Linux agents is performed and one or more agents does not have the .NET Framework installed, the update no longer fails.

Platform
02095727

Group and node status in the Web Console now stays consistent between the primary web server and additional web servers. Previously, the same object could show a different status (for example, Critical and OK) after the Configuration Wizard ran.

Platform
02056947

When an agent is assigned to an additional polling engine and automatic node creation is enabled, deploying the agent to the additional polling engine again after a failover to the primary polling engine no longer results in an error.

Platform
02068408

You can now change the number of rows displayed on the new All Active Alerts page.

Platform
02085101, 02086241

Discovery Ignore List now properly removes interfaces when you choose “Remove from Ignore List,” and those interfaces appear in scheduled discovery results again as expected.

Platform
02089347 When the IIS AppInsight cleanup and maintenance routines run, each polling engine processes requests only for the sites it polls, instead of all sites. This change prevents long wait times and blocking in the SolarWinds Observability Self-Hosted database. SAM
02094673

When a CMAN Kubernetes probe is collecting container data from a cluster that contains pods with a container status of null (the pod never had any containers), the probe no longer returns a NullReferenceException.

SAM
02080859

Node maintenance schedules now keep all node settings, such as credentials, intact when multiple schedules unmanage or remanage the same nodes at the same time. Previously, some settings could be cleared during these bulk actions.

Platform
02106984

The Platform Connect advanced setting HideIconToAllUsers can now be used to hide the icon for all users without causing the Core Business Layer service to fail at startup.

Platform
02096472, 02103051, 02096398

Known issues

Last updated: April 20, 2026

SAM RabbitMQ components after migration to SolarWinds Message Bus

After a deployment is migrated to SolarWinds Message Bus, customers who use SolarWinds Observability SAM templates that include RabbitMQ components may see those components reported as down. These components are no longer applicable after the migration and must be disabled manually in the SAM template. Automatic disabling of these components is not currently available.

Resolution or workaround: In the SolarWinds Platform Service Manager, confirm that the message bus is SolarWinds Message Bus. Once confirmed, disable RabbitMQ components (RabbitMQ Folder Size, RabbitMQ Service Monitor) in each affected SAM template.

HTTPS monitors fail after upgrade to 2026.2 RC1

After upgrading to 2026.2 RC1, HTTPS component monitors may fail with the message “The return code is different than expected.” Although the request returns 200 (OK) in earlier steps, the final HTTP status code is reported as null, causing the monitor to fail regardless of the actual response.

Resolution or workaround: On each polling engine, edit SolarWinds.APM.Probes.dll.config and set the HTTPS fallback setting to false. The default location of the file on polling engines is C:\ProgramFiles\SolarWinds\Orion\.

For HTTPS monitors that are assigned to agents, the same change will need to be made on the respective agent. The default location for this file on agents is C:\Program Files (x86)\SolarWinds\Agent\Plugins\APM.

Example:

<add key="HttpsProbeAllowFallbackToSpecificSecureSocketLayerProtocols" value="false" />
