NetFlow Traffic Analyzer 4.2.3 Release Notes

 

 

Last updated: September 13, 2017

These release notes describe the new features, improvements, and fixed issues in NetFlow Traffic Analyzer 4.2.3. They also provide information about upgrades and describe workarounds for known issues.

For NTA environment requirements, see NTA 4.2.3 System Requirements.

Starting with NTA 4.2, the NTA Flow Storage Database is no longer supported on additional pollers and additional websites, and needs to be installed on a dedicated server. This includes NTA versions 4.2.1 through 4.2.3.

New features and improvements

Read this section for descriptions of the new features and improvements NTA offers in this release, or compare NTA 4.2.3 with previous releases of NTA.

NTA 4.2.3 is an Orion Platform product, and it runs on Orion Platform 2017.3.

Windows Authentication for SQL

Secure the connection between your Orion server and your SQL server

Increase your security compliance by using Windows authentication for both day-to-day data storage and retrieval between your Orion server and your SQL server and during the initial setup of your database server in the Configuration Wizard. 

Do not use a Windows account with a password policy applied.

You can also enable SSL directly in the Configuration Wizard to encrypt the information exchanged between your Orion server or additional polling engines and your SQL server, independent of SSL settings on your SQL server.

SSL must be configured on your SQL server to utilize this feature.

SolarWinds Orion Installer

Use the SolarWinds Orion Installer to install and upgrade one or more Orion Platform products simultaneously in your environment. When installing new products into an existing Orion environment, the Orion Installer verifies compatibility between the product versions and notifies you if additional steps are needed. The Orion Installer also supports upgrades from older versions of the software with a generated upgrade path, merging the capabilities of the Product Upgrade Advisor into the installer.

  • .NET 4.6 is required to use the new installer and will be downloaded when you run the installer. Do not stop the installation after installing .NET 4.6 due to compatibility issues with older versions of SolarWinds software. A reboot may be required after installing .NET.
  • To eliminate compatibility issues, all required Orion Platform products are upgraded when you complete the Orion Installer. 

The installer:

  • Installs or upgrades all products from a single screen. You do not need to download files for each product.
  • Provides an easy-to-follow install path when required. If you upgrade from an older product version, the installer provides upgrade paths custom-made for your current environment so you can complete complex upgrades and installations with ease.
  • Runs preflight checks to ensure your environment specifications match the system requirements for selected product installs. If changes are needed, the installer provides guidance for required versions.
  • Automatically starts the Configuration Wizard as needed after product installs to complete database and configuration tasks.

Do not use the SolarWinds Orion Installer to upgrade a remote NTA Flow Storage Database. For more information on upgrading a remote NTA Flow Storage Database, see this article.

Multi-subnet High Availability

Distribute HA pool members to different subnets in this new update to SolarWinds High Availability for near instantaneous, automated failover to a secondary server on a different subnet. Create an HA pool , update your secondary server, and activate HA in your current Orion environment just as easily as before. 

» Read more about multi-subnet High Availability (DR)

PerfStack

Get both broad and in-depth visibility into your environment by correlating disparate data points across your infrastructure, including on-premise, cloud, and hybrid environments, in easy-to-read charts.

This version of PerfStack™ includes:

  • Real-Time Polling at approximately one second intervals for selected metrics.
  • Increased the number of supported metrics and products
  • View the data behind supported charts with the Data Explorer.
  • Drag and drop entities to the chart area.
  • Open an analysis project directly from an entity with common metrics already added.
  • Go to the details page for an entity from the Performance Analysis dashboard.

Other improvements

  • Deploy Orion agents to Raspberry Pi (Raspbian version 8.0 on ARMv6 or ARMv7 processors, 32-bit). If you upgrade to this version, you can install any Linux agent plug-ins on Rasberry Pi devices.
  • Improved memory performance.

This version changes the system requirements. .NET 4.6.2 is required and Windows Server 2008 and SQL Server 2008 are no longer supported for installations. 

New customer installation

For information about installing NTA 4.2.3 see the NTA Getting Started Guide.

Before you upgrade!

If you are upgrading from a previous version, be aware of the following considerations:

  • When upgrading to NTA 4.2.3, if you added a site binding to a host name before you upgrade, you must bind the Orion Web Console to a fully qualified domain name (FQDN). See this article.
  • When upgrading to NTA 4.2.3 with custom menus, you can not see the Performance Dashboard link in the menu. For details, see this article.
  • After NTA 4.2.2, future releases will no longer support Windows OS 2008 and 2008 R2 and Microsoft SQL Server 2008 R2. SolarWinds recommends that you upgrade to Windows Server 2012, 2012 R2, or 2016 at your earliest convenience. For more information, see Deprecation notices notices.
  • Always use the Product Upgrade Advisor to build your upgrade path.
  • See the NTA Upgrade Guide for more detail.

How to upgrade

If you are upgrading from a previous version, use the following resources to plan and implement your upgrade:

  • Use the new SolarWinds Orion Installer to upgrade one or more Orion Platform products simultaneously in your environment. For more information, see SolarWinds Feature: SolarWinds Orion Installer.
  • Use the Product Upgrade Advisor to determine your upgrade path. Based on your current environment and versions, the Product Upgrade Advisor provides an ordered list of how to proceed with the upgrade.
  • If you are upgrading:
  • When you are ready, download the upgrade package from the SolarWinds Customer Portal.
