• 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.

New features and improvements in SolarWinds Observability Self-Hosted Essentials

The following features are exclusive to customers with a SolarWinds Observability Self-Hosted license.

Technical Preview: AI Agent

The AI Agent continues as a Technical Preview in this release.

• Added support for virtual entities, including clusters, hosts, and virtual machines.

• Added support for application templates.

• User interface updates:

  • Added a send button.

  • Added character count to show the limit when chatting with the agent.

  • Added suggested prompts after opening the AI chat window and after each response.

• Added the ability to analyze historical performance metrics, not only the current state.

Enhanced cloud entities support

Microsoft Azure

• Added support for Azure Table Storage, providing visibility into Azure cloud services and underlying infrastructure.

• Added support for Azure Virtual WAN, enabling monitoring connectivity across branches, VNets, and hybrid environments.

• Added an Azure service cost details page with flexible filtering and detailed breakdowns by subscription, services, and resources.

Amazon Web Services (AWS)

• Added support for AWS Elastic Beanstalk, enabling monitoring of entire application environments and improving visibility into autoscaling behavior and application performance.

• Added support for AWS Transit Gateways, providing insight into gateway health, utilization, and capacity planning for central network hubs.

• Added an AWS service cost details page with key performance indicators, time-series views, and filtering by service, region, resource, and tags.

Google Cloud Platform (GCP)

• Added support for Google Kubernetes Engine (GKE), including clusters, nodes, and workloads, aligned with other entities.

• Added GCP Cloud Routers with visibility into BGP session state, route quotas, dropped routes, flapping and control-plane health.

• Added GCP service cost details page with flexible filtering, time‑based trends, forecasts, and optimization insights.

Alerting Engine – Condition-based suppression

Extended the alerting engine with a native Suppress Condition that applies to all alerts, allowing child alerts to be automatically muted when a related parent object is unhealthy. For example, interface or BGP peer alerts can be prevented from firing when the parent node is down. Suppressed alerts are still recorded for visibility and reporting, but trigger/reset actions and escalations are skipped, reducing alert noise from cascading failures across the environment.

Support for Azure VNets

Extends IPAM capabilities to include Azure Virtual Networks (VNets) and their associated subnets, and IP addresses of monitored VMs.

This feature enables unified visibility and management of both on-premises and Azure cloud network address spaces, bridging hybrid environments in a single interface.

Option to clear old, orphaned DHCP scopes and DNS zones

Contains an option to clear old, orphaned DHCP scopes and DNS zones to improve network hygiene and operational efficiency. By providing a built-in cleanup feature that enables network administrators to easily remove outdated and unused DHCP scopes and DNS zones, IPAM can accurately reflect the current network state.

Updates to the Manage Subnets & IP Addresses interface

Applied the following updates to the Manage Subnets & IP Addresses pane:

• Extended the Advanced Search types.

• Added 256 pages as an option in the pagination drop-down list.

• Improved the scroll bar on the left pane.

• Updated the move function so a recent destination can be reused.

Improved compound search function

The LA search bar has been enhanced to support compound text queries using logical operators.

Updated Last XX logs entries widget

The Last XX logs entries widget has been updated for improved log filtering and analysis. This includes tag-based enhancements and improved filtering behavior.

SD-WAN: Support for on-premises Fortinet FortiManagers

Extended SD-WAN monitoring for on-premises FortiManager deployments. This release adds API-based visibility into orchestrators, edge devices, and WAN uplinks, with support for on-premises authentication methods.

Extreme Networks switch monitoring

Extended Layer 2 and Layer 3 monitoring and hardware health visibility for Extreme switches. SolarWinds Observability Self-Hosted now collects additional L2/L3 data (MAC, VLAN, STP, routing) and adds a vendor-specific hardware health poller to monitor chassis temperature, fans, and power supply status on supported Extreme models.

Cisco modular hardware health

Improved hardware health monitoring for Cisco chassis. This release adds visibility into line cards, power supplies, and fan trays, including reset reasons and last status changes.

Updated ignored monitor types for F5 devices

The default ignored monitor types for F5 devices were updated to include additional, less commonly used monitor types. This reduces the number of API requests sent to F5 devices during each polling cycle.

To change which monitor types are ignored, update the value for IgnoredMonitorTypes in the F5 section of Centralized Settings. See Access the Advanced Configuration settings.

If you customized the value before upgrading, your existing values are preserved.

Delete credentials or unlink credentials from nodes

In VNQM Credentials Manager settings, you can delete credentials or unlink credentials from a node without deleting the credentials.

New features and improvements in SolarWinds Observability Self-Hosted Advanced

Customers with a SolarWinds Observability Self-Hosted Advanced license receive all Essentials updates, plus the following features exclusive to Advanced customers.

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
01982486, 02016697	The User Inventory Results view no longer displays inaccurate results and data duplication.	UDT
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
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
OO-57477	On the Node Details page, when you click Service Control Manager and attempt to start, restart, or stop any service, the action no longer fails with an error such as the following: Service "serviceName" with status "Stopped" can't be started because - "Unknown (-1)"	SAM
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	An issue was resolved that caused the Configuration Wizard to fail during upgrades with the following message: System.ServiceModel.EndpointNotFoundException: There was no endpoint listening	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
02009097	When the friendly name of a DHCP scope includes a backslash (\) character, the Manage Subnets page no longer fails to load with a JSON parsing error. Previously, scanning a server with such a scope and navigating to Discovered Subnets caused the right panel to hang and become unresponsive.	IPAM
01987300, 02071868	An issue that caused inaccurate End of Sales dates was resolved.	NCM
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
02046715	F5 LTM virtual server polling has been corrected so that the VirtualIPAddress / IPAddressIndex relationship is updated whenever the virtual IP (VIP) address changes, even when it was initially empty. This ensures that SolarWinds Observability Self-Hosted always uses the current VIP when correlating F5 virtual servers, which prevents missed or incorrect alerts when VIPs are reconfigured.	NPM
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
02045468, 02076938	SD-WAN tunnel processing failures on Cisco Viptela Orchestrator devices were resolved. The issue was caused by duplicate tunnels in the device response (same tunnel, different destination port). Tunnel handling has been updated to include the port in the peer name, so duplicate entries no longer trigger the error An item with the same key has already been added, and all Viptela tunnel data is polled and displayed correctly.	NPM
N/A	You can now change the number of rows displayed on the new All Active Alerts page.	Platform
02072551, 02086603	An invalid or incorrectly formatted IP address for a node no longer prevents the VNQM business layer from starting with errors such as: ERROR SolarWinds.BusinessLayerHost.PluginInstanceAppDomain - Plugin "VNQM Business Layer" failed to start. System.FormatException: An invalid IP address was specified.	VNQM
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
02054680	Database Diagnostics were extended to include the new FortiGate firewall tunnel and virtual-domain tables or views, so diagnostics bundles now reliably capture configuration and metric data for FortiGate firewall devices without errors.	NPM
00335342	The DNS Records Mismatch widget no longer incorrectly flags IPv6 reverse DNS entries as mismatches on multi-homed hosts configured with both IPv4 and IPv6 addresses.	IPAM
02085164	When an ICMP Path Jitter operation is created and the source is a Cisco node, the timeout value is no longer set to 0, preventing the probe from polling.	VNQM
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
02032093	SolarWinds Observability Self-Hosted is now able to collect and connect associated VLAN information for Arista switches.	NPM
01991663, 02058791	Advanced search and Manage Subnets performance has been improved. Database index optimizations have significantly reduced query execution times in large environments. Customers experiencing search query timeouts due to high custom property counts or large IP node datasets should see a significant improvement after upgrading.	IPAM
02094703	Azure Virtual Network Gateways monitoring now continues to collect and store data even when some gateways do not have a Public IP address configured, preventing gaps in Azure gateway visibility caused by failed polling in these cases.	NPM
02099780, 02106827, 02107003	The MIB browser works with SNMPv3 nodes and correctly displays the OID.	NPM
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.	Platform

Installation or upgrade

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" />
