  • Total number of machine agents and containers reporting to a single Controller is 30,000.
  • Total number of app agents reporting to a single Controller is 100,000.
  • Monitored servers are considered stale 30 days after they go offline. They are purged from the Controller database when that time limit is reached.
  • Docker Visibility is supported on Linux only. 


  • It is good practice to check the server frequently to make sure it has the latest Windows updates installed. WMI (Windows Management Instrumentation) updates are especially important , because because the agent uses WMI to collect Server Visibility metrics.
  • The monitored server should have at least 4 cores or multiple CPUs. WMI processes can be highly resource-intensive, especially on Windows Server 2012.
  • If you do not have a Server Visibility license, or if you want to collect Basic metrics only, configure the agent to use the JavaHardwareMonitor extension.
  • The Windows Machine Agent uses the following extensions by default:
    • JavaHardwareMonitor (for Basic metrics)
    • ServerMonitoring (for Server Visibility metrics)
  • The HardwareMonitor extension is not recommended on Windows.
  • If you do not have a Server Visibility license, or you want to collect Basic metrics only, Server Visibility should not be enabled on the agent.
  • If you want to enable Server Visibility on a Windows server with a .NET APM agent installed, you must enable .NET Compatibility Mode on both the Controller and the Standalone Machine Agent.
