How can I determine the quality of service in WCF?

Question

I want to determine the following QoS Attribute of my service:

1. Response Time
2. Reliability
3. Availability

I will be creating an application that will select a service based on the mentioned attribute.

Answer 1

Some or all of these attributes could be gleaned from switching on diagnostics for the service, but as this is likely to hurt performance, you may alternatively want to consider writing a few custom performance counters for your application.
