IADLXPerformanceMonitoringServices

Navigation: ADLX SDK References → ADLX Interfaces → Performance Monitoring

The IADLXPerformanceMonitoringServices interface provides methods to configure the performance monitoring functionality and to obtain the performance data.

InterfaceId:	IADLXPerformanceMonitoringServices
Smart Pointer Interface Name:	IADLXPerformanceMonitoringServicesPtr
Inherits:	IADLXInterface
Inherited By:	N/A

The IADLXPerformanceMonitoringServices interface provides:

The configuration for the performance metric sampling.
The methods to start and stop the performance metric sampling.
Access to the data from the performance metric buffer.
