NTA 4.2.2 Release Notes

Last updated: March 14, 2017

These release notes for NTA 4.2.2 describe the new features, improvements, and fixed issues in this release. They also provide information about upgrades and describe work-arounds for known issues.

For NTA environment requirements, see NTA 4.2.2 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 and 4.2.2.

New features and improvements

Read this section for descriptions of the new features and improvements NTA offers in this release, or compare NTA 4.2.2 with previous releases of NTA.

NTA 4.2.2 is an Orion Platform product, and it runs on Orion Platform 2017.1.

Performance Analysis charts

Use the Performance Analysis (PerfStack™) dashboard to get both broad and in-depth visibility into your  environment by correlating disparate historical data points across your infrastructure, including on-premise, cloud, and hybrid environments in easy to read charts. Click My Dashboards > Home > Performance Analysis to get started correlating and analyzing data collected by your SolarWinds Orion solution to troubleshoot issues, identify root causes of intermittent issues, and make data-driven decisions on infrastructure changes.

Native SSL support for the Orion Web Console

Seamlessly bind SSL certificates to the Orion Web Console and enable HTTPS connections using the Configuration Wizard. The Configuration Wizard scans the Orion server for valid SSL certificates that you can choose for the binding, or you can generate a self-signed certificate on the fly.

Other improvements

  • Use the Critical node status to trigger an alert or filter data in a report. 
  • Set a custom node status to Critical or Warning using an alert action. 
  • Use the Web-based SSH client when FIPS is enabled.

New customer installation

For information about installing NTA 4.2.2, see the NTA Administrator Guide.

Before you upgrade!

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

  • When upgrading to NTA 4.2.2, 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 4.2.2 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. NTA 4.2.2 currently supports these versions. SolarWinds recommends that you upgrade to Windows Server 2012, 2012 R2, or 2016 at your earliest convenience. For more information, see End of support notices.
  • Always use the Product Upgrade Advisor to build your upgrade path.
  • Always upgrade NPM first. NPM includes platform features to support all Orion products. See the NPM Upgrade Guide for more detail.
  • 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 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.
  • Use the multiple products upgrade guide for upgrading NTA and other modules (NPM, SAM, NCM, etc.). Each guide includes checklists and instructions to help you plan and execute your upgrade.
