我无法让EventType功能在Serilog中正常工作,就像关于here的博客一样。
我正在使用以下Nuget软件包:
首先,我创建了一个 EventTypeEnricher :
public class EventTypeEnricher : ILogEventEnricher
{
public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
{
var crypto = new SimpleCrypto.PBKDF2();
var hash = crypto.Compute(logEvent.MessageTemplate.Text);
var numericHash = BitConverter.ToUInt32(Encoding.UTF8.GetBytes(hash), 0);
var eventId = propertyFactory.CreateProperty("EventType", numericHash);
logEvent.AddPropertyIfAbsent(eventId);
}
}
这似乎可行(稍后会详细介绍,但是在该方法的结尾,可以观察到在 EventId 变量中添加了 EventType 值的属性调试时)。
我创建了一个扩展方法,该方法添加了该浓缩器:
public static LoggerConfiguration WithEventType(this LoggerEnrichmentConfiguration enrichmentConfiguration)
{
if (enrichmentConfiguration == null) throw new ArgumentNullException(nameof(enrichmentConfiguration));
return enrichmentConfiguration.With<EventTypeEnricher>();
}
然后在配置Logger时使用它:
Log.Logger = new LoggerConfiguration()
.Enrich.WithEventType()
.ReadFrom.Configuration(configuration)
.CreateLogger();
我要这样写错误:
logger.Write(LogEventLevel.Error,
contextFeature.Error,
MessageTemplates.LogEntryDetailMessageTemplate,
new LogEntryDetail
{
Exception = contextFeature.Error,
Message = "Bad Stuff",
Timestamp = DateTime.UtcNow,
MessageTemplate = MessageTemplates.LogEntryDetailMessageTemplate,
Severity = LogEventLevel.Error
});
我的Serilog应用程序设置部分如下:
"Serilog": {
"Using": [ "Serilog.Sinks.File", "Serilog.Sinks.MSSqlServer", "MyAssembly" ],
"Enrich": [ "EventTypeEnricher" ],
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"System": "Warning"
}
},
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "Logs//Errorlog.log",
"fileSizeLimitBytes": 1073741824,
"retainedFileCountLimit": 30,
"rollingInterval": "Day",
"rollOnFileSizeLimit": true
},
"restrictedToMinimumLevel": "Verbose"
},
{
"Name": "MSSqlServer",
"Args": {
"connectionString": "Data Source=(local);Initial Catalog=ADb;User Id=Serilog;Password=securepwd;",
"tableName": "ErrorLogs",
"autoCreateSqlTable": false,
"period": 30,
"columnOptionsSection": {
"disableTriggers": true,
"clusteredColumnstoreIndex": false,
"primaryKeyColumnName": "Id",
"addStandardColumns": [ "LogEvent" ],
"removeStandardColumns": [ "Properties" ],
"additionalColumns": [
{
"ColumnName": "EventType",
"DataType": "int",
"AllowNull": true
}
],
"id": { "nonClusteredIndex": true },
"level": {
"columnName": "Level",
"storeAsEnum": false
},
"timeStamp": {
"columnName": "Timestamp",
"convertToUtc": true
},
"logEvent": {
"excludeAdditionalProperties": true,
"excludeStandardColumns": true
},
"message": { "columnName": "Message" },
"exception": { "columnName": "Exception" },
"messageTemplate": { "columnName": "MessageTemplate" }
}
},
"restrictedToMinimumLevel": "Verbose"
}
]
}
我的数据库表如下:
CREATE TABLE [dbo].[ErrorLogs](
[Id] [bigint] IDENTITY(1,1) NOT NULL,
[EventType] [int] NULL,
[Message] [nvarchar](max) NULL,
[MessageTemplate] [nvarchar](max) NULL,
[Level] [nvarchar](128) NULL,
[TimeStamp] [datetime] NOT NULL,
[Exception] [nvarchar](max) NULL,
[Properties] [nvarchar](max) NULL,
[LogEvent] [nvarchar](max) NULL,
CONSTRAINT [PK_ErrorLogs] PRIMARY KEY NONCLUSTERED
尽管自定义浓缩器中的代码正在运行,但数据库中的EventType列始终为空。
它也不会写入文件接收器。
任何人都可以看到我在做错或丢失的事情吗?

更新至Serilog.Sinks.MSSqlServer预发行版本5.1.3-dev-00232
解决了此问题,因为当前稳定版本未读取所有columnOptionsSection
部分
Install-Package Serilog.Sinks.MSSqlServer -Version 5.1.3-dev-00232
以下更新的配置将解决您的问题,因为您错过了EventType
字段的表映射

记录器配置如下
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration)
.CreateLogger();
