Troubleshooting Connection Issues Between SolarWinds Platform and Azure Database

Reviewing the connection metrics reveals intermittent failures when the SolarWinds Platform attempts to connect to the Azure database named SolarWindsOrion. Azure’s “Deny Public Network Access” setting being enabled can cause failures. This setting restricts access to the database from public networks, requiring connections to use a Private Endpoint within the virtual network.

Overview

This article addresses connection problems observed between the SolarWinds Platform and an Azure SQL Database. Logs indicate multiple failed connection attempts, which can impact the platform’s ability to collect and process data effectively.

Product section

Orion Platform

Cause

The connection failures are caused by Azure SQL Database’s security configuration where “Deny Public Network Access” is set to Yes. This prevents the SolarWinds Platform from establishing a connection over the public internet, enforcing the use of private network endpoints for database access.

Resolution

To resolve these connection issues, ensure that the SolarWinds Platform connects to the Azure SQL Database using a Private Endpoint configured within your virtual network. Review and adjust your Azure SQL Database connectivity settings as needed. For more details, see Azure’s documentation on Deny Public Network Access and Private Endpoints:

Deny Public Network Access: https://docs.microsoft.com/azure/azure-sql/database/connectivity-settings#deny-public-network-access
Private Endpoint Setup: https://docs.microsoft.com/azure/sql-database/sql-database-private-endpoint-overview#how-to-set-up-private-link-for-azure-sql-database

If your configuration is correct and connection issues persist, it is recommended to open a support ticket with Microsoft for further assistance. (Source: https://docs.microsoft.com/azure/azure-sql/database/connectivity-settings#deny-public-network-access)
