Hi Sasidhar,

• From the shared error "The remote server returned an error: (407) Proxy Authentication Required", looks like there is any proxy configured on the Machine level or instrumented application level or network level and your proxy needs credentials.
  Could you please verify and configure proxy in the config.xml  for the communication between Agent and controller. You can find more information related to this in Proxy Element section link below 
  https://docs.appdynamics.com/display/PRO45/.NET+Agent+Configuration+Properties
  For example - 
  

  <controller host="mycontroller.example.com">
    <application name="MyDotNetApplicaition"/>
   <proxy host="myproxy.example.com"port="3128"enabled="true">
       <authentication enabled="true"user_name="MyProxyUser"password="password"domain="mydomain.com"/>
     </proxy>
  </controller>

  After configuring the proxy configuration. You would need to restart the Agent coordinator service and then restart the IIS/instrumented application services. After that apply the load and then check the behavior.
  
  

Thanks

Please do not share the config file here as this community platform. As Satyam suggested please modify the config.xml to include

<proxy host="myproxy.example.com"port="3128"enabled="true">
     <authentication enabled="true"user_name="MyProxyUser"password="password"domain="mydomain.com"/>
   </proxy>

Thanks,

we have already added those line in config for the previous installation istelf.

but , we are not able to see the data getting generated.

[Raunak.Mohanty]

The error in the logs suggests that you have not provided proxy authentication information or the provided info is not correct. Can you please double check with your Network Team?

If you have access to the support system, please create a ticket directly.  Otherwise, let us know so that we can share a SFTP location to get the logs from you.

Thanks,
