New Vulnerability Dashboard and Risk scorecard

This release introduces a new vulnerability and risk dashboard, available for Hybrid Cloud Observability Advanced users. View vulnerability and risk severity, determined by imported CVE information from CVEs based on CVSS v3. Schedule CVE data imports, and match CVE information to individual nodes. See calculated risk scores for individual monitored nodes and an aggregated risk scored for your environment.

Platform Connect supports more device types

Platform Connect now supports sending information for more device types to SolarWinds Observability, including application and virtualization.

Greater visibility for simplified SD-WAN monitoring

Real-time Tunnel and WAN metrics like service provider, packet loss, latency, and jitter are now available for use in dashboard widgets and PerfStack for Meraki, VeloCloud, and Viptela SDWAN devices.

Anomaly Based Alerts improvements

Anomaly Based Alerts now includes a new visual representation of the normal operating range (NOR) of a device’s metrics. The entity detail page contains NOR charts for every observed metric present for the entity that is triggering an Anomaly-Based Alert.

You can now define anomaly-based alerts for virtualization entities. See the list of supported entities with their metrics below:















AlertStack improvements

AlertStack is now available under the “Alerts and Activities” menu.

The AlertStack cluster detail page now supports filtering of occurrences together with maps. Occurrences can be filtered based on the Status and Element Type. Accordingly, the map nodes reflect this filtering as well.

AlertStack now supports creation of incidents in SolarWinds Service Desk (SSD) for AlertStack clusters. This action can be done for clusters in open or suspended states only.

Case number Description
01189602, 01296329, 01268284

In deployments with additional polling engines (APEs), attempting to integrate the SolarWinds Platform with DPA would install the DPA Business Layer on the APE. This caused problems with the DPA integration, including:

  • Application relationships added on the Manage Client Application Relationships page were automatically removed.

  • Integration fails with the message There was an error when trying to enable the integration with the DPA server: Establishing federation with jSWIS failed.

  • Attempting to add a DPA server returns the message Cannot find a DPA server at this address or port. Check your DPA server details and network connection.

01231016 When custom properties used in alerts are created in a different SolarWinds Platform product, the associated column in the All Active Alerts page in EOC is not blank.

When you run a report that queries the SolarWinds log database, the results of the query are shown instead, not the message Query is not valid.


In a large, complex environment, network configuration management jobs and inventory jobs run as expected.


Network configuration management jobs no longer make unnecessary APE license checks, which were causing the jobs to run slowly.

00837847, 01358148, 01426785

Inventory collection was updated to prevent database blocks, which were affecting performance.

01352472 If you run a job that saves the results of a policy report to a file, and the file name includes a macro, the macro is parsed correctly and the report's content and formatting are accurate.
01336072 When SolarWinds high availability (HA) is deployed, a network configuration search performed after a failover includes all configs. The search is not limited to only the most recently downloaded configs.

A vulnerability that could expose a password has been fixed.


A misspelled word in INFO messages in the NCM.Collector.Jobs_[*].log file has been corrected.


The Config Details page shows the downloaded time based on the SolarWinds Platform time zone, not UTC time.

01288735, 01387785

When an inventory job retrieves a large Flash Size value, it records the value correctly and no longer returns the following error:

Arithmetic overflow error converting expression to data type int.


Real Time Change Notification works as expected when the IP address provided to it is not the primary IP address for the node.*

01428683, 01330623, 01349629

In 2023.2, the default timeout value for SWJobEngineWorker2x64.exe was increased from 20 minutes to 2 hours. In deployments with a large number of jobs that did not finish before the 2-hour timeout, memory usage increased significantly. To prevent this issue, the default timeout value has been decreased to 20 minutes.

01295129, 01350421, 01428125

When the SolarWinds Platform is configured to use Windows authentication, running interface percentile traffic reports no longer returns an error.


If an interface name includes special characters, the special characters are no longer escaped on the Interfaces with High Percent Usage (no paging) resource. This behavior was preventing database maintenance from running as scheduled.


The load time for the Interface Availability widget has been significantly decreased.

01349629, 01362966

By default, network discovery enables all pollers on a device. So, if a topology poller is disabled on the List Resources or Manage Pollers page, it is enabled again when network discovery runs. A new advanced configuration option is available to enable you to override this default behavior. If do not want certain topology pollers to be enabled when network discovery runs:

  1. Open the Advanced Configuration options page by pasting the following into your browser URL field after the hostname or IP address:


  2. Under Topology, locate the PollersDiscoveryBlackList field.

  3. Enter a comma-separated list of topology pollers that should not be enabled when network discovery runs.

01348970, 01350142, 01361854, 01362953, 01420814, 01430172

Out-of-the-box Switch Stack alerts can be copied and edited, and they are triggered as expected.

01235174, 01401553

Universal Device Poller gauges load without errors and performance is improved.


If application data is corrupted, the Manage Applications and Service Ports page no longer attempts to list the applications. Corrupt data does not prevent the page from opening with the following message:

Unexpected Website Error
Sequence contains no elements

Additionally, a daily maintenance task detects and removes any corrupt application data.


If a user without permission to view NetFlow data attempts to access a NetFlow page, permissions are evaluated and the Restricted page message is displayed before the page loads. The page is no longer loaded and then hidden, and attempts to refresh the page do not affect performance.


A change to the NetFlowInterfaceSources_Metadata table in the SolarWinds Platform database prevents deadlocks in environments with a large number of VMware devices.

01400259, 01419304, 01420644

If a deployment includes more than one application template with the same name, the Configuration Wizard no longer fails with the following error:

Database configuration failed: Error while executing script- Subquery returned more than 1 value.

01360008, 01379355, 01390806, 01399847, 01400259

The SolarWinds Platform Web Console no longer becomes unresponsive or stops functioning due to missing keys in the cloud monitoring resource file.


On the Node Details Summary page, when you click Real Time Event Viewer and then click the Message column for an event, the Message Details popup opens as expected.


When you add a node with Microsoft SQL Server 2022 deployed, AppInsight for SQL is discovered.

01290468, 01305182, 01317562, 01320352, 01320666

During upgrades data from old tables is migrated successfully and the obsolete tables are removed. In a previous version, incomplete data migration could cause issues such as:

  • The Configuration Wizard failed with the message Invalid object name 'APM_ComponentStatus_Hourly.

  • The SolarWinds Platform database size decreased significantly.

  • The Application Component Details page did not consistently display messages.

01183556, 01337907, 01353375, 01389703

If the Configuration Wizard fails during an upgrade, attempting to rerun the wizard no longer fails with the message Error while executing script- There is already an object named 'CLM_CloudJobSettings' in the database.


When a problem occurs with the API poller, the following message was improved to provide more information about the cause of the problem:

Index was outside the bounds of the array.

01142194, 01357225, 01438644

When a node is deleted or unmanaged, Application Dependency Mapping (ADM) polling does not continue for that node. In previous versions, continuing to poll a deleted or unmanaged node for ADM data caused the ADM_ProcessingQueue table to become very large.


Long status messages associated with an application monitor are displayed correctly after an upgrade.


Alerts on API Pollers that should be triggered when the response time exceeds a threshold are no longer triggered when the response time is below the threshold.


If ADM polling is disabled for the SolarWinds Platform, the node detail page does not display the Application Dependency Polling Enabled check box.

00990851, 01415486

If AppInsight for IIS runs for long periods, the APM_IisBb_Request_Detail table no longer grows without limits, causing performance issues.

01372348, 01384875

The CreateApplication verb in SWIS for the AppInsight for SQL template now works when you are using a remote node and database. Issues with credentials and connection testing have been resolved.


The default poll no longer fails when more than one array is in a Nimble cluster.


The Vserver Status widget and the Vservers on this Cluster widget now show the same Vserver capacity data.


The Ethernet Ports Used Over Time now shows data for the selected time period instead of only the data for the current day.


When a wireless node is discovered with UDT port monitoring enabled and devices from the node are added to the Watchlist, the Watchlist widget no longer displays type conversion errors such as:

Conversion failed when converting the nvarchar value 'Vanguard_WLC' to data type int.


The Port Details widget now displays the MAC address, IP address, or Hostname for all devices.

00570890, 00582046, 00717223

The All User Log Ins widget displays data about the currently open endpoint, not the first endpoint that was opened.

01314714, 01333769, 01351695, 01365630, 01365850, 01382555, 01398156, 01412701, 01420009, 01426518, 01436135

The Port Details widget displays IP addresses even if the VLAN port is not monitored.*

01308188, 01332779, 01380614, 01382170, 01396520, 01404094

When a node uses automatic private IP addressing (APIPA), the vendor and machine type are reported correctly.

01353982, 01401047

Database maintenance no longer fails with the following message:

SolarWinds.Data.DatabaseMaintenance.StandardTableHandlerDAL - Failed to execute procedure: VIM_dbm_Clusters_ComputeDiskDepletion System.Data.SqlClient.SqlException (0x80131904): Arithmetic overflow error converting expression to data type bigint.

Cursor is not open.


The bulk insert query no longer runs slowly and causes performance issues on the database.


The Calls by Region widgets display the correct data.

01348659, 01371344

IP SLA operations function correctly, and the ipsla.bussiness.layer log file no longer includes the message Violation of PRIMARY KEY constraint.

01238012, 01294332

The FTP server is no longer filled with failed files, and VoIP views displays call manager information correctly.


After a call manager is removed, any associated CDR files are no longer processed, which prevents putting an unnecessary load on the FTP server.

01373525, 01378655

Call managers are polled only by the assigned polling engine, not by all polling engines.


When CDR files for different call managers are stored in separate folders on the FTP server, CDR files for all call managers are processed. VNQM no longer ignores CDR files for all call managers except the last one added.

01435916, 01441340

Avaya Call Manager now shows the correct numbers of phones.*

01269194, 01439830

Avaya RTCP data is collected and displayed as expected. Logs no longer include errors associated with the UTC offset.*


A large number of CDR or CMR files on the FTP server no longer cause an out of memory exception.*

*This fix was added after the RC release.
