I’m using Serilog’s file sink for logging in a .NET 8 application. I have configured the file sink to roll over when the file size limit is reached, but the naming convention is problematic for my use case. Here’s my current configuration:
.WriteTo.File(
path: "C:/Logs/MyApp.log",
fileSizeLimitBytes: 5242880, // 5 MB
rollOnFileSizeLimit: true,
retainedFileCountLimit: 5
);
With this setup, the log files are named as MyApp.log
, MyApp_001.log
, MyApp_002.log
, etc. However, the file without a numeric suffix is not the most recent file. For example, after some logging activity, the files might look like this:
- MyApp.log – older logs
- MyApp_001.log – older logs
- MyApp_002.log – older logs
- MyApp_003.log – most recent logs
I need the most recent log file to always be named MyApp.log
so that I can provide direct links to the latest log without having to adjust for a rolling numeric suffix. How can I configure Serilog to reverse the naming convention, so the current log file remains without a suffix and older log files are the ones that get numerically suffixed upon rolling?
