Monitoring a service


Monitoring a service works for:


native services

.Net services

mixed mode services.


Native Services


If you are working with native services you must use the NT Service API in your service as well as using the Monitor a service method below.


.Net Services


Memory Validator won't attach until some .Net code is executed.


If there is native code being called prior to the .Net code, Memory Validator won't monitor that code, only the native code called after the first .Net code that is called.


To monitor any native code called prior to your .Net code, use the NT Service API.


note When working with Memory Validator and services, you still start the service the way you normally do - e.g. with the service control manager.


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


To start monitoring a service:


menu Launch menu instructionStep Services instructionStep Monitor a service... instructionStep shows the Monitor a service dialog below


Or use the shortcut


 b_f6  Monitor a service



The monitor a service dialog


First ensure the service is installed, but not running.


Set the service to monitor, choose whether to start collecting data right away, and click OK.





Service to monitor instructionStep type or Browse to set the service name to monitor


OK instructionStep waits for the service to start before injecting into it


Start the service in the normal manner, e.g. from the control panel, the command line or programmatically.



Data collection


Type of data collection instructionStep Are you only interested in Native data, .Net data or both Native data and .Net data?


Native Only instructionStep Ignore all .Net data in the target application.


.Net Only instructionStep Ignore all Native data in the target application.


Mixed Mode instructionStep Collect both Native and .Net data from the target application


This setting cannot be changed after the application is launched


Collect data from application instructionStep If it's the startup procedure you want to validate, obviously start collecting data from launch.


Depending on your application, and what you want to validate, you may want to start collecting data immediately, or do it later.


If your program has a complex start-up procedure, initialising lots of data, it may be much faster not to collect data until the program has launched.


seeAlsoSee the section on controlling data collection for how to turn collection on and off after launch.
