Can you check library versions related to Serilog in the deployed application directory?
This library depends on Serilog.Sinks.Http
which is actually producing that file.
Hello @mantasaudickas
I am using serilog.sinks.logz.io7.2.0 version.
Serilog.Sinks.Http 8.0.0
I see.. but here you see what is referenced, but not what is deployed :)
Have you tried to enable Serilog diagnostics like described here: https://github.com/serilog/serilog/wiki/Debugging-and-Diagnostics ?
No, I didn't. Is it necessary for debugging?
Normally you can see if any internal errors are happening which helps to identify actual cause why logs are not sent to the server.
Ok, I am adding Serilog.Debugging.SelfLog.Enable(msg => Debug.WriteLine(msg));
at startup then deploy.
But where I can check these logs?
I think you should use:
var file = File.CreateText(...);
Serilog.Debugging.SelfLog.Enable(TextWriter.Synchronized(file));
Where you can specify path and file path where these logs should be written.
Debug.WriteLine does not log in release mode and in order to write something to file you need to do additional stuff like: https://stackoverflow.com/questions/7926577/writing-c-sharp-debug-output-to-txt-file
I found this logs inside file:
2023-05-05T08:35:52.0976470Z Received failed HTTP shipping result BadRequest: {"malformedLines":3,"oversizedLines":0,"successfulLines":97}
2023-05-05T08:35:54.5301179Z Received failed HTTP shipping result BadRequest: {"malformedLines":3,"oversizedLines":0,"successfulLines":97}
Maybe you can try to examine buffer file and try to identify which ones are malformed? Not sure how.. but maybe just by looking into you can find some special/invalid symbols used or smth..
I found a log file(Date.txt) which is not looked a like valid JSON file.
Is there any way to delete old log files (like bookmark and logs(date).text files from code)?
Log files are deleted based on retention settings: https://github.com/serilog-contrib/Serilog.Sinks.Logz.Io/blob/master/src/Serilog.Sinks.Logz.Io/LogzioSinkConfigurationExtensions.cs#L145
Library does not provide any explicit support to delete files. You probably can use some methods from here: https://learn.microsoft.com/en-us/dotnet/api/system.io.file?view=net-8.0
But be aware - you might loose your logs. And I think it is better to investigate what caused these issues instead of simply deleting files.
Btw, whole file is not a valid JSON - only log entry (line) should be a valid json.

I found one entry that is not a valid JSON in the whole record.
Ohk, Thank you for the quick reply.
Hello Team,
My application development logs are visible on the Logz.IO dashboard but in the case of Prod not. I have found one difference b/w both files below: (Additional XT text is there in the bookmark file)
Please let me know how to fix this issue my API is deployed on Azure App Services that's why I am unable to delete files there.
Thank You.
