NTA 4.4 System Requirements

 

Updated October 5, 2018

Supports: NTA 4.4

SolarWinds NTA requires:

  • Appropriate SolarWinds NPM version hosted on the same server.
  • The NTA Flow Storage database account requires the ALTER ANY CONNECTION permission in order to schedule and optimize the daily database maintenance task. This ensures that SolarWinds minimizes the performance impact of the maintenance task, and maintains the overall performance of the database. For information on commands to use to grant privileges to specific users, see the NTA Flow Storage database requirements section.
  • Microsoft SQL Server 2016 SP1 or later instance for the Flow Storage database.

Polling engine requirements

The following requirements ensure the scalability benefits of SolarWinds NTA:

Type Requirements
Operating system

64-bit operating system: Microsoft Windows Server 2012 and later

If you have more than one polling engine, make sure they are all installed on 64-bit operating systems.

Deprecation notice: Although you can install Orion Platform 2018.2 products on Windows Server 2012 and 2012 R2, mainstream support for these versions is ending and they will not be supported on future Orion Platform versions. SolarWinds strongly recommends that you upgrade to Microsoft Windows Server 2016 or later at your earliest convenience.

SolarWinds NPM

Version 12.3

Databases

Microsoft SQL Server 2012 and later for Orion SQL database.

Deprecation notice: Although you can use SQL Server 2012 with Orion Platform 2018.2 products, this version is deprecated and will not be supported on future versions of the Orion Platform. SolarWinds strongly recommends that you upgrade to Microsoft SQL Server 2016, 2017, or later at your earliest convenience.

The NTA Flow Storage database is where SolarWinds NTA stores your flow data. The NTA Flow Storage database requires a Microsoft SQL Server 2016 SP1 or later instance.

A connection to Orion SQL database is required because CBQoS data and some additional low level details are still stored in Orion SQL database.

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 or NTA Flow Storage Database 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 or NTA Flow Storage Database 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 2008 R2 SP1.
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.

Virtual machine requirements

SolarWinds NTA may be installed on VMware Virtual Machines and Microsoft Virtual Servers if the following conditions are met in your virtual environment:

SolarWinds NPM uses SNMP to monitor your network. SNMP traffic is generally assigned low priority, and thus you can experience gaps in monitoring data.

SQL server requirements

Multiple SolarWinds Orion server installations using the same database are not supported.

If you install on a virtual machine, you must maintain your SQL Server database on a separate, physical drive.

NTA Flow Storage database requirements

  • See What are the hardware recommendations for the NTA 4.4 SQL Flow Storage database for more information.
  • NTA requires SQL Server 2016 SP1 or later to run the NTA Flow Storage database.

    Deploying the NTA Flow Storage database on SQL Server 2016 SP1 Express is not recommended in a production environment due to performance and other limitations. For more information about SQL server Express, see Editions and supported features of SQL Server 2016 (© 2017 Microsoft, available at https://docs.microsoft.com, obtained on February 20th, 2018).

  • The NTA Flow Storage database account requires the ALTER ANY CONNECTION permission in order to schedule and optimize the daily database maintenance task. This ensures that SolarWinds minimizes the performance impact of the maintenance task, and maintains the overall performance of the database. Using SQL Management Studio, run the following command:

    USE master

    GRANT ALTER ANY CONNECTION TO <grantee> [ AS <grantor> ]

Orion database requirements

The following table lists software and hardware requirements for your SolarWinds Orion database server using SolarWinds NPM license levels.

Requirements SL100, SL250, SL500 SL2000 SLX

SQL server

SolarWinds supports Express, Standard, or Enterprise versions of the following:

  • SQL Server 2012, 2012 SP1, 2012 SP2, or 2012 SP3
  • SQL Server 2014 or 2014 SP1
  • SQL Server 2016
  • SQL Server 2017

SolarWinds strongly recommends using the 64-bit version of SQL Server.

  • Due to latency effects, SolarWinds does not recommend installing your SQL Server and your Orion server or additional polling engine in different locations across a WAN. For more information, see Install SolarWinds software and SolarWinds database (SQL Server) across a WAN.
  • You can set the database recovery model to Full Recovery if you use Always On Availability. SolarWinds recommends Simple database recovery mode to ensure best performance.

SQL Server collation

  • English with collation setting SQL_Latin1_General_CP1_CI_AS
  • German with collation setting German_PhoneBook_CI_AS
  • Japanese with collation setting Japanese_CI_AS
  • Simplified Chinese with collation setting Chinese_PRC_CI_AS

We support CI database on an CS SQL Server.

We do not support case-sensitive databases.

SolarWinds recommends the following configuration:

  • A hardware RAID Controller with a battery backed-up write back cache
  • Disk Subsystem 1 Array 1: 2x 146 GB 15K disks RAID 1 (mirroring) for the OS
  • Disc Subsystem 2 Array 2: 2x 146 GB 15K disks RAID 1 (Pagefile + Extra Storage)
  • Disk Subsystem 3 Array 3: with 6x 15k 146 GB or 300 GB disks configured in a RAID 1+0 array for your SQL MDF and FILEGROUPS.
  • Disk Subsystem 4 Array 4: with 4x 15k 146 GB or 300 GB disks configured in a RAID 1+0 array for your SQL LDF Transaction LOG file
  • Disk Subsystem 5 Array 5: with 4x 15k 146 GB or 300 GB disks configured in a RAID 1+0 array for your tempdb data file
  • Disk Subsystem 6 Array 6: with 4x 15k 146 GB or 300 GB disks configured in a RAID 0 array for your tempdb log file
  • Due to intense I/O requirements, a RAID 1+0 drive is strongly recommended for the SolarWinds database, data, and log files with a dedicated drive for the server operating system and tempdb files.
  • Other RAID configurations can negatively affect your SQL Server's performance.
  • Mirrored drives for the OS and RAID 1+0 for database data files are recommended.
  • Solid state drives (SSD) are recommended for all components.

Per Windows standards, some common files may need to be installed on the same drive as your server operating system. You may want to move or expand the Windows or SQL temporary directories.
