I am trying to capture the host / server's ipaddress within a .NET Core 2.0 application. The $machinename variable captures the server's name but how do you capture the server's IP address? The name is meaningless to my team but IP address is critical.

Lets say you have a static IP-address, then you can do this:



var localIpAddress = LookupIpAddress(); // See https://stackoverflow.com/a/50386894/193178
NLog.GlobalDiagnosticsContext.Set("LocalIpAddress", localIpAddress);


Then you can use it target layout like this:



layout="$longdate|$level|$logger|$message|$gdc=LocalIpAddress"


If your IP-address sometimes are changing, then you can setup a background-thread/timer to refresh the NLog-GDC-value.

  • Not right now. You are welcome to create a pullrequest (github.com/NLog/NLog/pulls). Maybe based on the API-call System.Net.Dns.GetHostAddresses() where it tries to prioritize Ipv4 and ignores loopback. See also: docs.microsoft.com/en-us/dotnet/api/…
