New features and improvements in SolarWinds Platform

Feature Adoption

The Feature Adoption section in My Deployment helps you enable and expand the use of key product features now includes suggestions for:

  • Gaining deeper insights into virtualization

  • Monitoring virtual servers

  • Monitoring storage arrays

  • Identifying unknown traffic

  • Monitoring configurations

  • Monitoring DNS and DHCP servers

  • Monitoring call quality

  • Monitoring configuration policies

Alerting

All Active Alerts page has been updated to the new framework. You can customize columns or edit the query used to build the table with custom entries.

Integrations

ServiceNow integration now supports OAuth based authentication.

SolarWinds Platform now integrates with SolarWinds Incident Response (earlier known as Squadcast). In this version, the integration is unidirectional - alerts from SolarWinds Platform are forwarded to SolarWinds Incident Response. Any acknowledgments on the incident response side are not reflected in SolarWinds Platform. Users can do additional correlation and suppress alerts using their Incident Response instance.

Maps

This release introduces several enhancements to map editing and management, making it easier to customize and work with Intelligent Maps.

  • Users can bulk edit multiple connections at once.

  • Users can import Network Atlas maps with linked backgrounds into Intelligent Maps.

  • Users must confirm that they want to remove a custom topology item before it is removed.

  • Users can see an icon and color indicator for text that contains hyperlinks.

  • Users can see hotkeys for actions in the More menu.

  • Users can hide autogenerated topology connections on maps.

Custom banners

Users can define customized in-product banners shown at the top of each page in the web console. These banners can be used for the following purposes:

  • Notification of scheduled upgrades

  • Classification of government data

  • Identification of deployments when multiple instances are deployed for a single customer

  • Notification of a known issue or outage

My Dashboards menu collapsed by default

For new installations, My Dashboards menu is set to the collapsed view. This provides a cleaner and easier to navigate experience for customers.

PerfStack metrics format change

PerfStack metrics now have a short, user-friendly unit format to simplify reading and understanding PerfStack charts. This helps with translating large numbers into more readable language, such as using kb, Mb, Gb instead of bytes.

Node status indicates polling issues

Node status now exposes any problem with failing WMI, WinRM, or SNMP polling when ICMP connection is working, including credential issues.

Updated MAC OUI data

The MAC OUI data has been updated to provide more accurate vendor details when analyzing MAC addresses in the SolarWinds Platform.

New features and improvements in SolarWinds Observability Self-Hosted Essentials

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

Network Routing Insights

Users can view routing paths across Layer 2 and Layer 3 by correlating metrics and integrating routing relationships such as next-hop, peer, interface, and VRF. Users can:

  • See how routes are resolved and identify the interfaces carrying them and their associated VRFs.

  • Analyze peer relationships by linking peer status to route and interface health to detect instability and flapping.

  • View port-channel membership and understand its relationship to all child interfaces.

  • Map VLANs and VRFs to routing and forwarding tables for better context and troubleshooting.

Virtualization

  • Added monitoring datastore performance metrics, VM disk and snapshot details for Proxmox VE environments.

  • Credential management for Proxmox VE has been improved.

Additional updates

  • Added new pollers for monitoring port channels.

  • Network Discovery in All Settings menu replaced with a link to Discovery Central.

  • Added a new widget for switch stacks, Switch Stack Member Ports.

Kea DHCP

Added Kea DHCP reservation support.

New widget

All nodes with Log Analyzer enabled now feature a widget displaying recent log events from that node in the nodes dashboard. This data is filterable by log type and severity.

Support for Juniper SwitchStacks

Users can monitor and detect stack membership changes, ring failures, and hardware faults on Juniper Switch stack.

CUCM support

Added support for Cisco Unified Communications Manager CUCM v15.x.

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.

Risk Analysis now includes exploitability score

  • Users can get more accurate risk scores for supported nodes with exploitability insights based on real-world likelihood.

  • Users can assess vulnerability risk more effectively using EPSS (Exploit Prediction Scoring System) integration, which provides probability-based exploit estimates.

SCM can now compare node configurations of two servers

SCM can now display differences in configuration files between two SCM nodes and can check configuration drifts between the two servers. For example, it can check the settings of multiple nodes in the same cluster/HA or check differences between staging and production environments.

New features and improvements in SolarWinds Observability Self-Hosted Enterprise Scale

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

Known issues

Upgrades fail when the Configuration Wizard attempts up create or update a configuration file

In some environments, the Configuration Wizard fails when attempting to create or update the sw.web.compression.config file.

Resolution or workaround: This issue will be fixed in a future release. Until then, complete these steps:

  1. Open the following file in a text editor:

    C:\ProgramData\SolarWinds\sw.web.compression.config

  2. Update the contents of this file to the following:

    <?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="sw.web.compression" type="SolarWinds.Orion.Core.Common.Configuration.WebCompressionSection, SolarWinds.Orion.Configuration" />
    </configSections>
    <sw.web.compression>
        <settings>
            <add name="" level="4" enable="True" install="True" />
            <add name="static" level="9" />
            <add name="dynamic" />
            <add name="dynamic.IIS6" enable="False" />
        </settings>
    </sw.web.compression>
</configuration>

  3. Save the file and rerun the configuration wizard.

The Last XX Audit Events widget does not load all events

After an upgrade to 2025.4, the Last XX Audit Events widget does not load events that occurred before the upgrade.

Resolution or workaround: You can use a custom table widget instead of the standard Last XX Audit Events widget.

This issue will be fixed in a future release.

URL-based filters in modern dashboards stopped working

Modern dashboards no longer recognize URL-based filters unless a global filter is explicitly configured on the dashboard.

Resolution or workaround: Use global filters. See Global filters on modern dashboards.

Cisco IPv6 reservation

Due to vendor limitations, Cisco IPv6 does not support IP reservations or static bindings and has not been implemented into IPAM.

Resolution or workaround: There is no workaround at the moment. SolarWinds is working to resolve this issue in a future release.

Some Azure accounts fail to poll Azure VMs

For some Azure accounts, attempts to poll Azure VMs fail, and errors such as the following are found in the logs:

ERROR SolarWinds.VIM.CloudMonitoring.Pollers.Azure.AccountAutomonitoringPoller - Unable to get azure VMs.

DEBUG SolarWinds.Orion.Pollers.Framework.PollersJob.PollersJobBase - Poller finished, Configuration- PollerType=N.Cloud.AccountAutomonitoring.Azure, NetObjectID=CVA:9, Result- PollResult:Failed

WARN SolarWinds.Orion.Pollers.Framework.PollersJob.PollersJobBase - Poller failed - ResultError: ErrorCode=10000, ErrorMessage=Azure account automonitoring poller has failed with unexpected error. This may be a temporary issue. Please try again in a few seconds.

Resolution or workaround: This issue will be fixed in a future release.

Upgrades fail because the Configuration Wizard encounters a database configuration error

During an upgrade, the Configuration Wizard might fail during the database configuration phase. The following error is displayed:

Error while executing script - The index 'IX_NetFlowAddressToResolveLowPriority_Timestamp' is dependent on column 'Reason'. ALTER TABLE DROP COLUMN Reason failed because one or more objects access this column.

Resolution or workaround: Follow the steps in the Support article Error during Configuration Wizard: “The index 'IX_NetFlowAddressToResolveLowPriority_Timestamp' is dependent on column 'Reason'”.

This issue will be fixed in a future release.
