I have problems to exclude healthchecks from serilog files.
Serilog.Filters.Expressions are installed and the StatusCode=200 line will be filtered.
appsettings:
"Serilog": { "MinimumLevel": { "Default": "Verbose", "Override": { "Microsoft": "Information", "Microsoft.EntityFrameworkCore": "Warning", "AspNetCore.HealthChecks.UI": "Warning", "HealthChecks": "Warning", "System": "Warning" } }, "Using": ["Serilog.Filters.Expressions"], "Filter": [ { "Name": "ByExcluding", "Args": { "expression": "EndsWith(RequestPath, '/healthcheck') and StatusCode=200" } } ], "WriteTo": [ { "Name": "Async", "Args": { "configure": [ { "Name": "File", "Args": { "path": "C:/Logs/MyApi/log.txt", "rollingInterval": "Day", "retainedFileCountLimit": 7, "buffered": true } } ] } } ] }
3.Programm
public class Program
{
public static int Main(string[] args)
{
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.Enrich.FromLogContext()
.WriteTo.Console()
.CreateLogger();
try
{
Log.Information("Starting web host");
CreateWebHostBuilder(args).Build().Run();
return 0;
}
catch (Exception ex)
{ Log.Fatal(ex, "Host terminated unexpectedly");
return 1;
}
finally
{
Log.CloseAndFlush();
}
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSerilog((hostingContext, loggerConfiguration) =>
{
loggerConfiguration.Enrich.FromLogContext()
.WriteTo.Elasticsearch()
.ReadFrom.Configuration(hostingContext.Configuration);
Log.Information("App started");
});
The logs changed from
2020-11-04 23:59:44.128 +01:00 [INF] Request starting HTTP/1.1 GET https://servicesp-rbg.company.com/MyApi/healthcheck 2020-11-04 23:59:44.128 +01:00 [INF] Request finished in 0.211ms 200 text/plain
to
2020-11-06 14:27:32.787 +01:00 [INF] Request starting HTTP/1.1 GET https://servicesp-rbg.company.com/My.Api/healthcheck
so the statuscode=200 filter is working but not the RequestPath 'healthcheck'.
