MetroLog stops logging when a few exceptions occurred

@basprins its hard to tell what might be the problem, but can you try these options. Sometime the file is locked and not released and other process cannot access it .

streamingFileTarget.IncludeLogger = true; this should create a different file for each logger and you will find which logger is not working...

Also, what i notice is if you have any Dependency injection or different projects where you are using the logger, then make sure you initialize the logger in each project.

Also worth trouble shooting if the configuration code is executed when the logger tries to log..?

Try those let us know if you go any further

@MMalikKhan that's very helpful commenting! Thanks a lot for that.

I left our machine in production for a day, and I can at least confirm that loggings is continued when a day is passed (and thus a new log file is created). So your suggestion of a file lock issue makes sense.

I will start with creating a file per logger, and when I learn more I will share it here.

Thanks again !

I added the "includelogger" in order to see which logs do continue to run. I made a copy of the directory listing, which indeed shows that a few loggers have stopped logging:

36bb0\LocalState\MetroLogs> ls | sort LastWriteTime -Descending

Directory: \\minwinpc\c$\Data\Users\DefaultAccount\AppData\Local\Packages\Durocan_ns7r26fq36bb0\LocalState\MetroLog

As you can see these three stop logging around 21:29

An (user handled) exception occurred at that time (the server connection failed, which recovered later). No sure why that would cause any trouble. The catch is nothing special either, just log and handle the exception....

You mentioned two other points:
Also, what i notice is if you have any Dependency injection or different projects where you are using the logger, then make sure you initialize the logger in each project.

Also worth trouble shooting if the configuration code is executed when the logger tries to log..?

Can you elaborate on both? How do I initialize the logger in another project (other than LogManagerFactory.GetLogger)? And how exactly do I see if configuration code is executed when the logger tries to log?

Hope you can clarify a few parts for me, or maybe you have other ideas that might help me further.

Many thanks again.
