The Monitoring Agent for Windows gathers data when requested to satisfy a workspace refresh, situation sampling of attributes, or historical data collection. All attributes in the attribute groups that make up a workspace or situation are gathered at that time. The default refresh/sampling intervals were chosen so that the agent does not put a significant load on the system as it gathers the data.
Most of the attributes gathered by the Monitoring Agent for Windows come from Performance Monitors (Perfmon). A few Application Programming Interfaces (API) and Windows Management Instrumentations (WMI) are used.
