title: Using Performance Counters to monitor WCF Service
body: <p>I have a requirement to monitor the average time it takes a WCF web service to process a service request. Researching on-line I see that one way is to use performance counters. I activated the counters using the web services' web.config file using:</p>
  
  <pre><code>&lt;system.serviceModel&gt;
    &lt;diagnostics performanceCounters="All" /&gt;
  &lt;/system.serviceModel&gt;
  </code></pre>
  
  <p>I can now view the relevant data in real time using perfmon (6.1.7600). 
  How can I create and output these values to a rolling log file that appends the information to the bottom? I've tried using perfmon but can't seem to find the option?</p>
