旧答案(不含
我在MVC5应用程序中使用Serilog和Serilog.Exceptions进行结构化日志记录。
我想从& Exception"的值中删除堆栈跟踪。日志中的字段。我知道我在RollingFile接收器中使用new JsonFormatter()，因此异常对象，例如ex，被格式化为ex.ToString()，整个对象被原样写入。
我使用new DestructuringOptionsBuilder().WithDefaultDestructurers()在"ExceptionDetails"中显示堆栈跟踪
是否可能只看到异常的名称作为" exception "字段的日志，而不是整个堆栈跟踪和其他细节作为ex.ToString()，而写到JSON文件接收器?
下面是我的异常日志:
{

}
这是我的Logger类:
public class Logger
{
private static readonly ILogger logger;
static Logger()
{
logger = new LoggerConfiguration()
.Enrich.WithUserName(anonymousUsername: "Not Authenticated")
.Enrich.FromLogContext()
.Enrich.With(new ThreadEnrich())
.Enrich.WithCaller()
.Enrich.WithMachineName()
.Enrich.WithHttpRequestId()
.Enrich.WithHttpRequestNumber()
.Enrich.WithHttpRequestClientHostIP()
.Enrich.WithHttpRequestType()
.Enrich.WithHttpRequestRawUrl()
.Enrich.WithMvcRouteData()
.Enrich.WithExceptionDetails(
new DestructuringOptionsBuilder()
.WithDefaultDestructurers())
.Enrich.WithDemystifiedStackTraces()
.WriteTo.RollingFile(new JsonFormatter(),
HttpContext.Current.Server.MapPath($"~/logs/log-.json"),
LogEventLevel.Debug,
fileSizeLimitBytes: 655360)
.CreateLogger();
}
public static void LogInformation(string info, object[] data = null)
{
logger.Information(info, data);
}
public static void LogDebug(string debug, object[] data = null)
{
logger.Debug(debug, data);
}
public static void LogWarning(string warning, object[] data = null, Exception e = null)
{
logger.Warning(e, warning, data);
}
public static void LogError(Exception e, string error, object[] data = null)
{
logger.Error(e, error, data);
}
}
任何关于我的Logger课程的建议也欢迎。
无论存在什么日志属性，"formatter "Serilog如何将标准日志信息(包括异常)转换为文本。
为了摆脱冗余，你需要使用JsonFormatter以外的东西。
如果您使用Serilog.Expressions，那么使用ExpressionTemplate很容易做到这一点。Serilog.Sinks.File的示例用法(其他接收器类似):
const string logTemplate = "{ { Timestamp: @t, Message: @m, Level: @l, Exception: ExceptionDetail, ..Rest() } }n";
Log.Logger = new LoggerConfiguration()
.Enrich.WithExceptionDetails()
.WriteTo.File(new ExpressionTemplate(logTemplate), "app.log")
.CreateLogger();
旧答案(不含Serilog.Expressions):
这是我使用的一个格式化器，它只是移动了&;exceptiondetails &;
namespace Serilog.Exceptions.Formatting;
using System.IO;
using Serilog.Events;
using Serilog.Exceptions.Core;
using Serilog.Formatting;
using Serilog.Formatting.Json;
/// <summary>
/// A JSON text formatter using structured properties for exceptions.
/// </summary>
/// <remarks>
/// Avoids the redundancy of <see cref="JsonFormatter"/> when used with <see cref="ExceptionEnricher"/>.
/// </remarks>
public class StructuredExceptionFormatter : ITextFormatter
{
private readonly string rootName;
private readonly JsonValueFormatter valueFormatter = new(typeTagName: null);
/// <summary>
/// Initializes a new instance of the <see cref="StructuredExceptionFormatter"/> class.
/// </summary>
/// <param name="rootName">The root name used by the enricher, if different from the default.</param>
public StructuredExceptionFormatter(string? rootName = null)
{
this.rootName = rootName ?? new DestructuringOptionsBuilder().RootName;
}
public void Format(LogEvent logEvent, TextWriter output)
{
output.Write("{"Timestamp":"");
output.Write(logEvent.Timestamp.UtcDateTime.ToString("O"));
output.Write("","Message":");
var message = logEvent.MessageTemplate.Render(logEvent.Properties);
JsonValueFormatter.WriteQuotedJsonString(message, output);
output.Write(","Level":"");
output.Write(logEvent.Level);
output.Write('"');
var propCount = logEvent.Properties.Count;
if (logEvent.Properties.TryGetValue(this.rootName, out var exceptionProperty))
{
output.Write(","Exception":");
this.valueFormatter.Format(exceptionProperty, output);
propCount--;
}
if (propCount > 0)
{
output.Write(","Properties":{");
var comma = false;
foreach (var property in logEvent.Properties)
{
if (property.Key == this.rootName)
{
continue;
}
if (comma)
{
output.Write(',');
}
else
{
comma = true;
}
JsonValueFormatter.WriteQuotedJsonString(property.Key, output);
output.Write(':');
this.valueFormatter.Format(property.Value, output);
}
output.Write("}");
}
output.WriteLine('}');
}
}
它将显示你的异常如下:

我研究了一下，我认为你应该检查一下Serilog过滤器。例如，您可以过滤事件字段、源，甚至过滤具有特定值的数据。你可以通过在你的日志配置代码或JSON文件中配置相应的过滤器来做到这一点。
