@awygle it can be well worth asking on SO with some details about use case (and posting a link back here in case someone happens to know). That and trying https://getseq.net ;)
@JinendraGhodke Hi! https://github.com/destructurama/attributed might be what you're looking for (or be able to be modified for it). HTH!
Trying to use Web.Config AppSettings
If course, i could use ForContext(nameof(MyClass)), but ForContext<Type>() is nicer :-)
Hey guys, I'm using appsettings.json style configuration for serilog, and was wondering what the json looks like (assuming it exists?) for doing assembly based changes of the minimum log level. I found a property called "overrides" but i didn't see in the documentation if this is actually how to do it, but what i tried did not work.
was hoping for something like this:
"Serilog": {
"MinimumLevel": "Debug",
"Overrides": [
{"System": "Warning"},
{"Microsoft": "Warning"}
]
}public class LoggerFactory : ILoggerFactory
{
Func<string> headerFactory = () => "date time;logtype;environment;ShipTracker build version;test case description;status";
public Serilog.Core.Logger Create()
{
var logger = new LoggerConfiguration()
.WriteTo.File(new CustomCsvLogging(), $"C:\\Dev\\Logs\\shiptracker-ui-{DateTime.Now}log.csv", hooks: new HeaderWriter(headerFactory))
// .ReadFrom.AppSettings()
.CreateLogger();
return logger;
}
}
my
CustomCsvLogging() is public class CustomCsvLogging: ITextFormatter
{
public void Format(LogEvent logEvent, TextWriter output)
{
output.Write(logEvent.Timestamp.ToString("dd-MM-yyyy H:mm"));
output.Write(";");
output.Write(logEvent.Level);
output.Write(";");
output.Write(logEvent.Properties[Configuration.Config.SynergyEnvironment]);
output.Write(";");
output.Write(logEvent.Properties["KEY"]); //App Build version
output.Write(";");
output.Write(logEvent.Properties["KEY"]); //test case description
output.Write(";");
output.Write(logEvent.Properties["KEY"]); //test status
output.WriteLine();
}
}
I want to know
output.Write(logEvent.Properties["KEY"]); for the header mentioned above and how to write values

FYI found it:

}
}
}

@apoorvup_twitter this might be a good one for Stack Overflow, there's a bit much detail to cover in chat format; I'll keep an eye on the
serilog tag and try to help out if I spot it
I have a question for you. I would like create a filter by class like we can have with "Override": {
"Microsoft": "Information",
"Microsoft": "Information",
@apoorvup_twitter firstly, I'd figure out what you want to do - use serilog, or raw code
If you're not very familiar with Serilog, I'd just write raw code like the answer suggests
If not, you're essentially writing a custom sink
At which point I'd have to ask: why?
I'd be looking to use getseq.net and/or use some low tech thing like opening the files in VS Code
Half the problem on your SO thread is that you havent truly answered any of the above
Your far more likely to get places out there, than atting folks here unfortunately

(I do appreciate you went to the trouble of writing on SO first and linking here and don't mind helping a bit - this is simply a matter of finding someone that has done what you want that has time - I have never felt motivated to write a custom sink outside of a test scenario)
I had a basic serilog logger in place that writes to an txt file. I wanted to extend the functionality by using custom sync and write few data as mentioned in the SO problem
ok, now we're talking...
I'd say you need to go look at custom sinks and simply write the thing - it'll be well worth the learning experience
CustomSync are not helping as I am a begineer
I unfortunately don't have time now to drill in, sorry
Help me once you feel free.
but I dont want to set too high expectations for a what is a watercooler channel for folks generally ineterested in serilog - ultimately your question is ideally progressed on stack overflow
I hope someone can help with this. I'm logging to elastic search in my dotnet core application but keep getting this exception

Hi all :wave: ... found some time to look at the staged logger initialization problem and put together: https://github.com/nblumhardt/serilog-reload - all feedback and sanity checking welcome (the code's still a proof-of-concept)
