Orion Platform 2018.2 Hotfix 3 includes WPM 2.2.2 hotfix 1 and is available on the SolarWinds Customer Portal for existing WPM 2.2.2 customers.  

For new installations of WPM 2.2.2, the SolarWinds Orion Installer includes this hotfix and earlier Orion Platform 2018.2 hotfixes.

Fixed issues

This hotfix addresses the following WPM issues. See Orion hotfix release notes for a list of fixed issues for other Orion Platform products in the hotfix bundle.









To avoid retaining excess cookies that could extend playback time or cause playback to fail, WPM worker processes delete cookies after playback.






Code was updated to resolve entities and prevent alerts such as "An issue on an object you are monitoring occurred at ${N=Alerting;M=AlertTriggerTime;F=DateTime}".





The WPM Playback Player Proxy service restarts after upgrading from WPM 2.2.1 to WPM 2.2.2. Previously, missing DLL files caused exception errors.


Apply this hotfix to an existing installation of WPM 2.2.2 running on Orion Platform 2018.2.


Install this hotfix on the Orion server (the main polling engine), on any additional polling engines or web servers, and High Availability (HA) servers.

  1. Use an administrator account to log into the server that hosts your SolarWinds Orion installation, also known as the Orion server.
  2. Log into the SolarWinds Customer Portal and download the Latest Hotfix Installer (Offline) for Orion Platform 2018.2 HF3 that includes WPM v2.2.2 Hotfix 1.
  3. Run the installation file, and follow the instructions in the installation wizard.

After applying this fix, the fixed issues outlined in this article should no longer occur.

Install the hotfix with SolarWinds High Availability

Use these instructions to install the hotfix with SolarWinds HA.

The HA pool must be disabled to begin installation. If you install prior to disabling, the pool is automatically disabled.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to disable.
  3. Toggle High Availability to Off.
  4. Install the hotfix on the primary server in the pool.
  5. Install the hotfix on the secondary server in the pool.
  6. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  7. Select the pool you want to enable and toggle High Availability to On.

The Orion Web Console verifies all SolarWinds product versions match across the HA pair before enabling. If you receive errors, check your product versions.

You may need to recreate the HA pool. For details, see Set up an HA pool.


You may need to run the Configuration wizard manually after uninstalling the hotfix.

  1. Use an administrator account to log into the Orion server.
  2. Run the Orion Service Manager, click Shutdown Everything, and close the Orion Service Manager.
  3. Navigate to Control Panel > Programs > Programs and Features > View installed updates.

  4. Select "Orion Platform 2018.2 HF3 - includes WPM v2.2.2 HF1 - Hot Fix 1", click Uninstall, and complete the uninstallation wizard.
