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
Direction Description
161 UDP SolarWinds Job Engine Outbound The port used for sending and receiving SNMP information.
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 http://192.168.0.3:8080.

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 the Main Polling Engine to the Additional Web Server, and from the Additional Web Server to the Main Polling Engine.

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
53 UDP SolarWinds High Availability Service outbound Used when failing over with a virtual hostname to update the virtual hostname's DNS entry and for periodic monitoring.
135 TCP SolarWinds High Availability Service bidirectional Used to remotely manage services including DHCP server or DNS server.
4369 TCP RabbitMQ bidirectional TCP ports 4369 and 25672 must be open between the main and secondary servers to allow RabbitMQ clustering between the two servers. These ports exchange EPMD and Erlang distribution protocol messages for RabbbitMQ. They do not need to be open in additional polling engine pools.
5671 TCP

SolarWinds High Availability

bidirectional Port 5671 must be open into the HA pool with the main Orion server from all Orion servers.
17777 TCP SolarWinds installer bidirectional Used when installing the standby server software. You can close this port after installation.
25672 TCP RabbitMQ bidirectional TCP ports 4369 and 25672 must be open between the main and secondary servers to allow RabbitMQ clustering between the two servers. These ports exchange EPMD and Erlang distribution protocol messages for RabbbitMQ. They do not need to be open in additional polling engine pools.

Network Atlas

Port

Service/Process Direction

Description

17777 TCP SolarWinds Information Service Bidirectional Remote instances of Network Atlas require TCP on port 17777 to either the SolarWinds NPM or the SolarWinds EOC server.

Nutanix ports

Port Protocol Service/Process Direction Description Encryption
22 SSH SolarWinds Job Engine v2 Outbound The port used for Nutanix hardware health monitoring.

Inbound

(DCE/RPC Locator service) Microsoft EPMAP. This port must be open on the target computer for remote deployment.

WMI is only needed for deploying the agent to a Windows server with the Add Node or Add Agent wizard. If you do not want to open WMI ports required for software deployment, you can use another deployment method for the Agent.

WMI also uses any random TCP port greater than 1024. See WMI portocalypse on THWACK.
