NetFlow Traffic Analyzer 2020.2 System Requirements
Release date: June 4, 2020
What requirements are you looking for?
On-premise requirements for NTA
SolarWinds NTA requires an appropriate SolarWinds NPM version hosted on the same server. To deploy NTA locally, on a server, review the Multi-module system guidelines.
You cannot install Orion Platform products on the same server as SolarWinds Access Rights Manager (ARM).
NTA Flow Storage database requirements
NTA and Orion Platform use two SQL databases - the Orion database and the NTA SQL Flow Storage database. The Orion database stores SolarWinds Orion configuration data and all collected performance and syslog data. The NTA Flow Storage database is where SolarWinds NTA stores your flow data.
| Type | Recommendation |
|---|---|
| SQL server |
SolarWinds recommends using a single SQL server instance for both the NTA Flow Storage database and the Orion database.
SolarWinds supports Express, Standard, or Enterprise versions of the SQL server. |
| Sizing |
Hardware recommendations for the NTA SQL Flow Storage database For an example configuration, see User scenario: Recommended SQL server disk configuration. |
For more information on deploying the NTA SQL Flow Storage database in NTA 2020.2, see NTA 4.4 and Later Adoption: Frequently Asked Questions.
Orion database requirements
For a complete overview of requirements for deploying the Orion database in an environment with SolarWinds NTA, see the Multi-module system guidelines.
Port requirements
The following table lists ports that SolarWinds NetFlow Traffic Analyzer uses to communicate with other devices and servers.
| Port | Protocol | Service/Process | Direction | Description |
|---|---|---|---|---|
| 80 | TCP | World Wide Web Publishing Service | Bidirectional | Port used for web console and any other web servers. |
| 137 | UDP | NetBIOS | Outbound |
Port for outbound traffic if NetBIOS name resolution is turned on. When NTA is trying to resolve the NetBIOS names of servers in their conversations, you may find a large amount of outbound UDP 137 traffic from the NTA collector to a number of external addresses. You can confirm the traffic by using the Flow Navigator to match the outbound connections to existing conversations. This is normal behavior when NetBIOS is enabled. An easy way to demonstrate the behavior is to disable NetBIOS in NTA and watch all outbound connections terminate. |
| 161 |
UDP TCP |
SolarWinds Job Engine v2 | Outbound | Port used for sending and receiving SNMP information, including polling CBQoS-enabled devices. |
| 1433 | TCP |
SolarWinds NetFlow Service SolarWinds NetFlow Storage Service |
Outbound | Port used for communication between the NetFlow Service and the existing SQL server. |
|
1434 |
UDP |
SolarWinds NetFlow Service SolarWinds NetFlow Storage Service SQL Browse Service |
Outbound | The port used for communication between the NetFlow Service and the Orion database. This port is required only if your SQL Server is configured to use dynamic ports. |
| 2055 | UDP | SolarWinds NetFlow Service | Inbound | Port for receiving flows on any SolarWinds NTA collector. |
| 5671 | TCP | RabbitMQ | Bidirectional | Rabbit MQ messaging. |
| 17777 | TCP | SolarWinds Information Service | Bidirectional |
Port for sending and receiving traffic between SolarWinds NPM and other Orion Modules. Port used for communication between remote Flow Storage Database and NTA Main Poller. |
| 17778 | HTTPS and TCP | SolarWinds Information Service | Bidirectional | Open to access the SolarWinds Information Service API and agent communication. |
| 17791 | TCP | SolarWinds Agent | Bidirectional | Open for agent communication on any SolarWinds Orion server running Windows Server 2016. |
| Device-specific | Any port required by a specific device. |
For a complete list of the port requirements for the SolarWinds Orion server, see the Port Requirements document.
Cloud deployment
When deploying NTA in cloud, SolarWinds recommends using the native SQL service for the NTA SQL Flow Storage database. You can install the NTA SQL Flow Storage database onto the following:
- Microsoft Azure SQL Database
If you choose to build a new Azure SQL database instead of using the native SQL service, review the section Azure instances required for additional databases.
- Amazon Web Service with RDS

You should also review the following resources for the exact product requirements beyond these minimums.
