Ports required by Orion Platform features
Additional Polling Engines
Additional Polling Engines have the same port requirements as the Main Polling Engine. The following ports are the minimum required for an Additional Polling Engine to ensure the most basic functions.
| Port |
Proto- col |
Service/ Process |

| 162 | UDP | SolarWinds Trap Service | Inbound | The port used for receiving trap messages. |
|
1433 |
TCP |
SolarWinds Collector Service |
Outbound | The port used for communication between the APE and the Orion database. |
| 1434 | UDP | SQL Browse Service | Outbound | The port used for communication with the SQL Server Browser Service to determine how to communicate with certain non-standard SQL Server installations. Required only if your SQL Server is configured to use dynamic ports. |
| 1801 | TCP | Message Queuing WCF | Bidirectional | The port used for MSMQ messaging from the Main Polling Engine to the Additional Polling Engine. |
|
5671 |
TCP |
RabbitMQ | Outbound |
The port used for SSL-encrypted RabbitMQ messaging from the Main Polling Engine to the Additional Polling Engine. |
|
17777 |
TCP |
SolarWinds Information Service |
Bidirectional |
The port used for communication between the Additional Polling Engine and the Main Polling Engine. |
Additional Web Servers
| Port | Protocol | Service/Process | Direction | Description |
|---|---|---|---|---|
|
80 |
TCP |
World Wide Web Publishing Service | Inbound |
Default additional web server port. Open the port to enable communication from your computers to the Orion Web Console. If you specify any port other than 80, you must include that port in the URL used to access the web console. For example, if you specify an IP address of 192.168.0.3 and port 8080, the URL used to access the web console is |
| 443 | TCP | IIS | Inbound | The default port for https binding. |
|
1433 |
TCP |
SolarWinds Information Service | Outbound |
The port used for communication between the SolarWinds server and the SQL Server. Open the port from your Orion Web Console to the SQL Server. |
| 1801 | TCP | Message queuing | Outbound | The port used for MSMQ messaging from the Additional Web Server to the Main Polling Engine. |
| 5671 | TCP | RabbitMQ | Outbound |
The port used for SSL-encrypted RabbitMQ messaging from the Additional Web Server to the Main Polling Engine. |
|
17777 |
TCP |
SolarWinds Information Service | Outbound |
Orion module traffic. Open the port to enable communication from all polling engines (both Main or Additional) to the Additional Web Server, and from the Additional Web Server to polling engines. |
Container monitoring
| Port | Protocol | Service/Process | Direction | Description | Encryption |
|---|---|---|---|---|---|
| 17778 | HTTPS and TCP | SolarWinds Information Service (SWIS) | Bidirectional | Communication between the SWIS API and container orchestrators. | SSL |
| 17799 | HTTPS | SolarWinds Cortex | Bidirectional | Communication between the Cortex REST API and container orchestrators. |
Additional container monitoring port requirements for orchestrators include:
- For Docker and Docker Swarm:
- 4043: Container port (internal Docker communication)
- 6784: Report status (internal Docker communication)
- For Kubernetes (K8s) and Microsoft Azure Kubernetes (AKS):
- 4043: Target port/Container port (internal Docker communication)
- 30043: Node port (internal Docker communication)
- For Apache Mesos:
- 4043: Mesos master server port (internal Mesos communication)
- 8080: Deployment service (internal Mesos communication)
High Availability
| Port | Protocol | Service/Process | Direction | Description |
|---|---|---|---|---|
