Layout ILogger scopes (ILogger.BeginScope) ?

v1.0.0-rtm-alpha5

Hi,

Is there any way I can render ILogger scopes (ILogger.BeginScope) in the NLog layout configuration for dotnetcore?

Thanks!

Hey! could you give an example?

Hi, see https://docs.microsoft.com/en-us/aspnet/core/fundamentals/logging in section "Log scopes", example from link:

public IActionResult GetById(string id)
{
    TodoItem item;
    using (_logger.BeginScope("Message attached to logs created in the using block"))
    {
        _logger.LogInformation(LoggingEvents.GET_ITEM, "Getting item {ID}", id);
        item = _todoRepository.Find(id);
        if (item == null)
        {
            _logger.LogWarning(LoggingEvents.GET_ITEM_NOTFOUND, "GetById({ID}) NOT FOUND", id);
            return NotFound();
        }
    }
    return new ObjectResult(item);
}

I assume your question has been answered, if not, let us know!

@304NotModified is there any additional config needed to make this work?

What I have so far:

• a call to UseNLog()
• an nlog target that has ${ndc} in its layout
• code that does ILogger.BeginScope(string)

But my output has empty strings where the ndc should be.

${ndc} was pre-1.0 of NLog.Extensions.Logging

It should be ${ndlc} now. - https://github.com/NLog/NLog/wiki/Ndlc-Layout-Renderer

See also some examples in the unit tests

${mdlc} is also described in the wiki:
