New features and improvements in WPM

WPM 2019.4.2 includes security enhancements and is signed with a new digital code-signing certificate.

To learn more about security enhancements, see the Orion Platform 2019.4.2 Release Notes.


New customer installation

To install WPM, review system requirements and use the SolarWinds Orion Installer, which you can download from the SolarWinds Customer Portal. See the Orion Platform Products Installation and Upgrade Guide to learn how to prepare your environment.

After installing WPM on the Orion server, you can deploy Web Transaction Recorders and WPM Players to remote systems to get an accurate sampling of your websites and services from the viewpoint of your end users. See the WPM Getting Started Guide for details.

How to upgrade

To prepare for the upgrade:

  1. Read these Release Notes.
  2. Confirm that all servers comply with WPM 2019.4 System Requirements.
  3. (Optional) Back up any custom code, such as modified SolarWinds .css files or added .js files.

In addition, note the following details:

To upgrade your entire Orion deployment, including all Orion Platform products and any scalability engines:

  1. Run the SolarWinds Orion Installer.

    Alternatively, click Settings > My Orion Deployment to upgrade from within the Orion Web Console.

  2. Update Web Transaction Recorders and WPM Players on remote systems. See the WPM Getting Started Guide.
  3. If you migrate the primary WPM application to a new server as part of an upgrade, update EngineIDs for SEUM agents.

Known issues

Return to top

Upgrading from Windows Vista to Windows 10 v.1607 or later on remote systems may overwrite WPM config files. If this occurs, backup (.BAK) files are created during WPM upgrades, available in C:\Program Files (x86)\SolarWinds\Orion\SEUM\Player.

WPM Recorders cannot count duration time on web pages with automated redirects. If steps recorded in the Deprecated WPM Recorder navigate to a web page with an automated redirect to another page, the time spent navigating to the first web page is not included in the overall duration time. Click here for a workaround.

WPM recordings that involve certificates may cause a WPM Player to crash on Windows Server 2016 Standard, Windows Server 2019 Standard, or Windows 10 v. 1607 or later. Click here for a workaround that adds the monitored page as a trusted site.

After upgrading from earlier WPM versions, unused SEUM-User accounts may remain and cause the WPM cache (Webcachev01.dat) to consume a large amount of disk space. Click here for steps to resolve the issue.
