System Monitor Installation Guide

If you have DP or XM appliances that shipped with agent software components pre-installed, you can upgrade those agents to this release using the instructions in the System Monitor Update Guide.

System Requirements for System Monitors

LogRhythm System Monitor Agents for Windows require the Microsoft .NET Framework 4.7.2. 

Windows hosts running System Monitors prior to version 7.2.x may not have .NET Framework 4.7.2 installed. If your Windows host does not have .NET Framework 4.7.2 installed, we do not recommend using the System Monitor Package Manager automatic update option. Since installing .NET Framework 4.7.2 requires a system reboot, the automatic update process will be disrupted and the Package Manager will not complete the installation process.

Performance requirements may vary depending on log sources and features used.


  • Minimum - 4 vCPU
  • Recommended - 8 vCPU+


  • Minimum - 8GB
  • Recommended - 16GB+

Disk Space

  • 5GB for System Monitor installation and prerequisites
  • Recommended: at least 50 GB for log data storage
Log data is stored on the System Monitor host only if the connection to the Data Processor is lost. In this case, log data must be stored locally until a connection is reestablished. The amount of disk space required for log data will vary according to collected log volume and the frequency and duration of a lost connection. Dedicated or high-volume deployments will require additional storage.

Microsoft .NET Framework

LogRhythm System Monitor Agents for Windows require the Microsoft .NET Framework 4.7.2.


The LogRhythm SIEM provides three types of System Monitor Agent licenses: System Monitor Lite, System Monitor Pro, and System Monitor Collector. For more information, see System Monitor Functionality by License: Lite, Pro, and Collector.
