SeriLog fileSizeLimitBytes属性asp.net核心

Question

We are using asp.net Core 1.1 and are using SeriLog to create log file within the application.

Now to control size of log file, I added attribute fileSizeLimitBytes

"Serilog": {
  "MinimumLevel": "Debug",
  "WriteTo": [
    {
      "Name": "RollingFile",
      "Args": {
        "pathFormat": "Logs/LogFileConf-{Date}-test.Log",
        "fileSizeLimitBytes": 500000
      }
    }
  ],
  "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
  "Properties": {
    "Application": "Sample",
    "Environment": "Test"
  }
},

In this case, writing to log file stopped and when I removed above attributes, writing to log file again started working

So I have added as follows "pathFormat": "Logs/LogFileConf-{Date}-test.Log", "fileSizeLimitBytes": 500000

I am not sure what I am missing here.

Project.json contains following reference.
"Serilog.Extensions.Logging": "1.2.0",
"Serilog.Sinks.RollingFile": "3.0.1",
"Serilog.Settings.Configuration": "2.1.0"

Can anybody help here to solve this issue?

Answer 1

Is your log file already > 500,000 bytes? That's not a high limit, so chances are the logging stops because the file is already above it.

See Serilog.Sinks.File 4.0+ if you are looking for roll-on-file-size.
