I have two loggers with Serilog and they save to different files. I want to create the loggers through the appsettings.json as opposed to code.
When I create my loggers through the Startup.cs configuration, I get a much more specific log and I prefer to have it that way as it's much clearer and will allow others to check the logs and understand what's going on without needing much technical knowledge. However, I want to apply this to the appsettings so that I can migrate the code to any other project that I may use.
FYI: I don't want to override the log level.
For example, with code I create my loggers like so:
Log.Logger = new LoggerConfiguration()
.WriteTo.ColoredConsole()
.WriteTo.Logger(lc => lc
.Filter.ByExcluding(Matching.FromSource("Microsoft"))
.WriteTo.File("Serilogs/Program_log_.txt", rollingInterval: RollingInterval.Day)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information))
.WriteTo.Logger(lc => lc
.Filter.ByIncludingOnly(Matching.FromSource("Microsoft"))
.WriteTo.File("Serilogs/ServerTrace_log_.txt", rollingInterval: RollingInterval.Day)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information))
.CreateLogger();
This generates the two separate outputs that I like the formatting of:
File 1: Readable, custom logs:
2019-01-18 11:18:09.873 +00:00 [INF] //Some custom log information
2019-01-18 11:18:09.875 +00:00 [INF] //Some more custom log information
File 2: Stack trace, server information:
2019-01-18 11:17:56.378 +00:00 [INF] User profile is available. Using '//A path' as key repository and Windows DPAPI to encrypt keys at rest.

When I do it by using the JSON appsettings it looks like so:
"Serilog": {
"Using": [
"Serilog.Sinks.File",
"Serilog.Filters.Expressions",
"Serilog.Settings.Configuration"
],
"WriteTo": [
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByIncluding",
"Args": {
"expression": "SourceContext = 'Microsoft'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "./Serilogs/server_logs_.log",
"rollingInterval": "Day"
}
}
]
}
}
},
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByExcluding",
"Args": {
"expression": "SourceContext = 'Microsoft.AspNetCore.Hosting.Internal.WebHost'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "./Serilogs/program_logs_.log",
"rollingInterval": "Day"
}
}
]
}
}
}
]
}
And this generates the two files.
File 1: Readable, custom logs:

So, by applying what feels the same technique, the outcome of the results are different as File 1 now contains more action information and File 2 contains the stack plus the custom log information although I want them completely separate.
