PathLatencyApp Service

This chapter describes the Cisco DCNM web services' API methods for the PathLatencyApp service.

Information About PathLatencyApp Service

This interface defines all the APIs exposed by the PathLatencyApp service facade.

createPathLatencySession

Creates one or more PathLatencySession objects.

Parameters
