  • 0

I have a self-hosted WCF service and I’m trying to enable performance counters, so I have added this to the web.config file :

<system.serviceModel>
  <diagnostics performanceCounters="All" />
  ...

After running my service and making sure that it is running, I then open perfmon.exe and try to add the performance counters. However there’s nothing shown in the “Instances of selected object” box.

my app.config:

<?xml version="1.0"?>
<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
        <listeners>
          <add type="System.Diagnostics.DefaultTraceListener" name="Default">
            <filter type="" />
          </add>
        </listeners>
      </source>
    </sources>
  </system.diagnostics>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
  <system.serviceModel>
    <diagnostics wmiProviderEnabled="true" performanceCounters="All">
      <messageLogging logMalformedMessages="false" logMessagesAtServiceLevel="false"
        logMessagesAtTransportLevel="false" />
    </diagnostics>
    <bindings>
      <ws2007HttpBinding>
        <binding name="soapBinding" maxReceivedMessageSize="1073741824">
          <readerQuotas maxStringContentLength="1073741824" maxArrayLength="1073741824" />
          <security mode="Message">
            <transport clientCredentialType="Windows" proxyCredentialType="None" realm=""/>
            <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" />
          </security>
        </binding>
      </ws2007HttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="defaultBehavior" name="SoapService">

          binding="ws2007HttpBinding" bindingConfiguration="soapBinding" name=""
          contract="ISoapService" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>

            <add baseAddress="http://localhost/SoapService/" />
          </baseAddresses>

      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="defaultBehavior">
          <serviceAuthorization impersonateCallerForAllOperations="false" />
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

Why does perfmon not show up any instances running?

btw, if the app.config doesn’t highlight for you running .NET v4

    Don’t know if it is still valid but let me try an answer.

    There are many things you should check :

    • You are targetting .net 4. Some counters will be in ServiceModelXXX 4.0.0.0.
    • Sometimes, you need to reinstall WCF counter. Visit this post for the command line.
    • Counters Instances do not exist until there is a first call (if not using appfabric autostart)
    • Your account should have the require permission : Performance Monitor/Log User
