You can expect to see the following Velocity operating system processes on any machine running a Linux operating system.

  • ArcGIS Velocity Enterprise Control Plane

  • ArcGIS Velocity Enterprise Feeds

  • ArcGIS Velocity Enterprise Gateway

  • ArcGIS Velocity Enterprise Metrics

  • ArcGIS Velocity Enterprise Real-Time Analytics

  • ArcGIS Velocity Enterprise Stream Server

User-created feeds, real-time analytics, and stream services operate within the Feeds, Real-Time Analytics, and Stream Server services. Turning off these services stop those items.

The Gateway service serves as the real-time messaging mechanism of the Velocity system. The Control Plane service is what controls the web app and orchestrates the configuration of the site. The remaining Metrics service is used to curate item and resource utilization metrics.

When performing any type of system maintenance, it is recommended to stop all six services to effectively shut down Velocity. This can be achieved from the Windows services pane. These services can be started in any order.
