Access logging

[tbonham]

Well issue #158 cover logging of request coming into YARP?

I'm just wondering if I need to do all the request logging myself or if YARP will handle it?

What fields do you want logged? Asp.Net already logs the protocol version, url, content-type, and length. It does not log all headers or body.

I was not aware of that. I'm just coming over to kestrel, I have always used IIS.

With my testing of kestrel, it isn't creating a log file. Is this another middle ware idea that I need to add?

I would like to be able to have a way to log the header for debugging reasons.

You need to turn the "Microsoft" logs up to "Information" to get request level logs.

The framework avoids bulk logging header as they may contain sensitive information like credentials. We recommend you log only the headers you care about in your own middleware.

@Tratcher Thank you for the documentation.

I reading the documentation. I think it going to take me sometime to get a log file the way I need it to be to log the traffic.

I thought it was going to be a little simpler than it is.

There's no log file like this built into Kestrel.
