7.22.0 System Monitor Release Notes - 1 October 2025

Release Details

LogRhythm System Monitor Agents for Windows require the Microsoft .NET Framework 4.7.2+ or .NET Core 8. 

• Before upgrading your System Monitor Agent .NET Framework 4 agent (installed pre-7.21), confirm that .NET Framework 4.7.2 or higher is installed.

• For information on determining which .NET version is installed, see Determine which .NET Framework versions are installed - .NET Framework.

• If an older version of .NET Framework 4 is installed, install .NET Framework 4.7.2 or higher and reboot your system during a planned maintenance window. Upgrading a .NET Framework 4 agent when the version of .NET Framework is older than 4.7.2 will trigger a reboot.

• Upgrading existing .NET Framework 4 System Monitor Agents to .NET Core 8 (7.21 or later) should not require a reboot, but should be done during a planned maintenance window.

New Features

O365 Beat

A new O365 Beat has been added to the Open Collector, replacing the API collection previously done through the System Monitor Agent. This new beat will address some issues that were experienced when using API collection for the O365 Management Activity log source.

For more information, refer to O365 Beat.

Resolved Issues & Enhancements

.NET Agent Upgrade Packages Issue

System Monitor Agent version 7.22 comes with a new .NET 8 agent update package to address an issue with agent upgrades. This package includes all of the following necessary files for the update:

• windowsdesktop-runtime-8.0.18-win-x64/86.exe

• LRSystemMonitor_64_7.22.0.2033.exe

• LRAgentUpdate.exe

• Property.xml 

This fix simplifies upgrades for users on version 7.22 agents moving to a newer/future version (like the eventual 7.23 .NET 8 agent). If you are on an older version of System Monitor Agent (7.21 or earlier), this fix is not available, and you will need to follow the special instructions below.

1. Run the upgrade packages for System Monitor Agent version 7.22.0.1035 (.NET 4) from any previous versions.
