note When working with NT services your account must have the appropriate privileges described in the User Permissions topic.



Attaching to your service


To use Performance Validator with NT Services you need to link a small library to your application and call two functions in the library.



The NT Service API


The NT Service API is provided to enable Performance Validator to work with services.


The API works just as well with normal applications, and the same considerations outlined here also apply generally.


When the NT Service API is used, source code symbols are acquired in the stub and sent to the Performance Validator user interface.



Monitoring the service


When working with Performance Validator and services using the NT Service API you don't start the service using Performance Validator.


Instead, you start the service the way you normally start the service - e.g. with the service control manager.


The code that you have embedded into your service then contacts Performance Validator, which you should have running before starting the service.


Once you've exercised your service and stopped it, Performance Validator will show the usual performance statistics.



Examples and help


We provide some Example Service Source Code to demonstrate how to embed the service code into your service.
