need to implement the logging in my custom solution.

Hi All,

I am working on  a application that has following components.

1. WCF web service.
2. Custom Ribbon action that invokes the web service using ajax framework.
3. Event receiver on item updated event that invokes the web service.
4. Silverlight Webpart that invokes the web service and displays the data.
5. Feature event receiver. 

Solution has been developed that is ready to be pushed to production. for diagnosis purpose i am want to implement the logging so that if there is any problem in production i can enable it and diagnose the problem.

As per my understanding.

1. Logging can't be implemented in Silverlight WebPart and Ribbon Custom Action technically.
2. For feature event receiver i suppose best option would be ULS logging.
3. For Web service i can use the microsoft enterprise libarary block for logging.
4. Event receiver that triggers on item updated event, i suppose i have two options, either use enterprise library block or use ULS.

in our production farm we have 3 front end servers so i suppose in both cases (ULS and enterprise library block) logs will be span on all the front end servers. i suppose reading the logs on all the front end server might be a night mare in production. 

i am not able to suggest myself what should be the best approach.  could you people would be provide me your suggestions.
