New features and improvements in NCM

There were no features or improvements added for NCM 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.

Fixed customer issues

01887898

Declarative Pipeline YAML parsing now correctly loads YAML definitions on systems using the Turkish locale by using an updated YAML parser, so configuration files are parsed without errors in this regional setting.

 Platform
01894020, 01945929, 02088770

World Map management now saves manual map changes correctly on German-language installations, without showing SWIS query errors.

 Platform
01915281 The performance of modern dashboard table widgets with horizontal threshold bars has been improved. Platform
01909120 When a SQL-based alert is triggered for a large number of nodes, the alert is triggered successfully and does not affect the performance of the Web Console. Platform
02021566

An issue that caused the Configuration Wizard to fail with the following error was fixed:

Invalid object name 'Ctx_C_Orion_NetMan_CloudMonitoring_VirtualNetwork'

Platform
01962578

SCP settings that include a path that ends with a backslash (\) are no longer recognized as valid by NCM. Paths that end with a backslash cause NCM config download jobs to fail.

 NCM
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
01976650 Running an inventory scan no longer generates database errors such as primary key violations, null values, and arithmetic overflows. NCM
02041303

When you create an alert, the trigger condition no longer includes the option Instance of NCM Node because this option failed to display all nodes. Instead, use the option Instance of Node in the trigger condition.

 NCM
02036053 When the Agent Management Service (AMS) is monitoring high availability pool tables, AMS no longer returns information about pools that are disabled. Platform
02040483

When you filter nodes displayed in an NCM chart, using a filter that includes custom property values no longer results in the following error:

Incorrect query condition

NCM
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
02059145 The Web Console Event Log displays events in local time instead of UTC, even when the SQL Server is in a different time zone. Platform
02032695, 02043746, 02072558

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
01987300, 02071868 An issue that caused inaccurate End of Sales dates was resolved. NCM
02077323

 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

Discovery and report scheduling now correctly run advanced schedules from the specified Starting On date and time, instead of delaying the first run by an extra interval.

 Platform
N/A

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
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
02045539 To prevent issues with the device template wizard in large environments, the size limit for POST requests made through the wizard has been increased. NCM
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

When a user attempts to open the custom property editor from the legacy Manage Nodes view, the custom property editor now opens as expected instead of intermittently logging the user out and displaying the login dialog.

 Platform
01931015, 02039092, 02093123

By default, the GET/POST alert action performs a header validation that can fail if the authorization header is not in the standard format. If this occurs, the centralized setting SendHttpRequestTokenHeaderValidation can be used to disable the header validation.
