EOC runs on the SolarWinds Platform (self-hosted). EOC release notes include the updates from the SolarWinds Platform (self-hosted).

New features and improvements in EOC

New EOC summary and alerting pages

EOC now offers new summary and alerting pages.

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.

Installation or upgrade

When planning your SolarWinds Platform deployment, keep in mind that EOC must be installed on a separate server from other products running on the SolarWinds Platform.

For new SolarWinds Platform deployments, download the installation file from the product page on https://www.solarwinds.com or from the Customer Portal. For more information, see Get the installer.

To activate your product in an existing SolarWinds Platform deployment, use the License Manager.

For upgrades, go to Settings > My Deployment to initiate the upgrade. The SolarWinds Installer upgrades your entire deployment (all SolarWinds Platform products and any scalability engines).

For more information, see the SolarWinds Platform Product Installation and Upgrade Guide.

For supported upgrade paths, see Upgrade an existing deployment.

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:

Open the following file in a text editor:

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

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>

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.
