How to access the REMOTE_ADDR property in nlog.config in an asp.net web service?

Question

I have a asp.net web service application (asmx). NLog has been configured on the project. I want to add the caller's ip address in the logfile. I need to access the REMOTE_ADDR property from within the nlog config file. This is what I tried.

<target name="file" xsi:type="File"
          layout="${longdate} ${logger} ${callsite} ${asp-request:item=REMOTE_ADDR} ${message}"
          fileName="${basedir}/logs/${shortdate}.log" />

the renderer ${asp-request:item=REMOTE_ADDR} should have done the trick. But nothing happens. What am I missing?

Note : I have added reference to the NLog.Extended.dll to the project.

Any help would be appreciated, please.

Answer 1

You've probably worked it out by now, but the code you were looking for is:

${aspnet-request:serverVariable=remote_addr}

Answer 2

As a side note using:

${ aspnet-request:serverVariable = remote_addr }

Produced the following error:

LayoutRenderer cannot be found: 'aspnet-request'

You have to install NLog.Web to make this work.
