The Distributed Trace Server (DTS) is responsible for defining policies based on which logs will 
be collected from the Distributed Trace Agents (DTA) at run-time. The logging policies can be 
configured via a Logging Policy MIB which is owned by the DTS. At system-start default policies 
will be used which can then be customized at run-time via the MIB. 

The Distributed Trace Agent (DTA) is a linkable library that makes the DTSv available to clients. 
The DTAs manipulate normalized logging information according to the filter descriptions 
configured in the Logging Policy MIB. If the Logging Policy MIB has not been configured, 
acceptable defaults engage. When it is configured, the DTSv selectively forwards filter 
descriptions to the appropriate DTAs according to the information described in the MIB. For a 
detailed description of the DTA refer to the Distributed Tracing Service Programmer's Reference 
. 

The HPI Integration Service (HISv) is a service which is only used internally by other NCS 
services, in particular the AvSv and the SPSv. It provides an abstraction from the actual HPI 
implementation used in the system. In the case of the NCS this implementation is OpenHPI.

The HISv allows its clients to interact with the underlying HPI interface. The main tasks of HISv 
are:

z

Publishing HPI events using ESDv channels and formatting expected by subscribing clients

z

Executing HPI APIs on behalf of other NCS services

z

Making hardware inventory information available

z

Overseeing the maintenance and manipulation of the SAF HPI MIB objects

The HISv is made up of the following two components:

z

HPI Chassis Director

z

HPI Adaption Private Library

The HPI Chassis Director (HCD) is an NCS process which is linked to a SAF-compliant 
implementation of the SAF HPI library.
