我正在尝试配置 serilog 以写入多个文件，但没有任何运气。 使用此配置，它只写入第二个文件？
{
"AllowedHosts": "*",
"Serilog": {
"Using": [ "Serilog.Sinks.File" ],
"MinimumLevel": "Debug",
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "c:\\temp\\audit-.log",
"rollingInterval": "Day",
"restrictedToMinimumLevel": "Information"
}
},
{
"Name": "File",
"Args": {
"path": "c:\\temp\\error-.log",
"rollingInterval": "Day",
"restrictedToMinimumLevel": "Error"
}
}
]
}
}
或者有什么方法可以将许多记录器加载到具有来自 appsettings.json 的不同配置的软件中。像这样的吗？
var errorLogConfiguration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
.AddEnvironmentVariables()
.Build();
_log = new LoggerConfiguration()
.ReadFrom
.Configuration(errorLogConfiguration)
.CreateLogger();
我找到了解决方案。为 appsettings.json、ErrorLog 和 AuditLog 创建了单独的部分。
"ErrorLog": {
"Using": [ "Serilog.Sinks.File" ],
"MinimumLevel": "Debug",
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "c:\\temp\\error-.log",
"rollingInterval": "Day",
"restrictedToMinimumLevel": "Error"
}
}
]
},
"AuditLog": {
"Using": [ "Serilog.Sinks.File" ],
"MinimumLevel": "Debug",
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "c:\\temp\\audit-.log",
"rollingInterval": "Day",
"restrictedToMinimumLevel": "Information"
}
}
]
}
现在我可以创建 2 个独立的记录器：
var errorLogConfiguration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
.AddEnvironmentVariables()
.Build();
var errorSection = errorLogConfiguration.GetSection("ErrorLog");
var auditSection = errorLogConfiguration.GetSection("AuditLog");
_log = new LoggerConfiguration()
.ReadFrom
.ConfigurationSection(errorSection)
.CreateLogger();
_auditLog = new LoggerConfiguration()
.ReadFrom
.ConfigurationSection(auditSection)
.CreateLogger();
哪个更适合我的需要。
由于 Serilog 和任何接收器的简单文档而苦苦挣扎了几天之后，这最终对我有用，无需创建任何单独的记录器：
"Serilog": {
"Using": [ "Serilog.Sinks.Async" ],
"MinimumLevel": "Verbose",
"Enrich": [ "FromLogContext", "WithDemystifiedStackTraces" ],
"WriteTo:Information": {
"Name": "Async",
"Args": {
"Configure": [
{
"Name": "RollingFile",
"Args": {
"RestrictedToMinimumLevel": "Information",
"Formatter": "FOOINC.API.Configuration.Logging.CustomRenderedCompactJsonFormatter, FOOINC.API.Configuration",
"PathFormat": "_logs\\info\\info-log.json"
}
}
]
}
},
"WriteTo:Error": {
"Name": "Async",
"Args": {
"Configure": [
{
"Name": "RollingFile",
"Args": {
"RestrictedToMinimumLevel": "Error",
"Formatter": "FOOINC.API.Configuration.Logging.CustomRenderedCompactJsonFormatter, FOOINC.API.Configuration",
"PathFormat": "_logs\\errors\\error-log.json"
}
}
]
}
}
}
希望这对任何人都有帮助！！
我的发现是经过一段时间的错误、重试并由于缺乏有关 Serilog 的文档而几乎放弃。他们在 GitHub 上有足迹：https://github.com/serilog/serilog-filters-expressions/issues/27。几乎每个线程都会得出相同的结论：您必须创建一个 SUBLOGGER。这是我的实现。对于此实现，您需要以下插件：
Serilog 异步
"Serilog": {
"Using": [ "Serilog.Sinks.File" ],
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"System": "Warning"
}
},
"WriteTo:Information": { //this name here can be changed
"Name": "Logger", //this name here is essential
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByIncludingOnly",
"Args": {
"expression": "@Level = 'Information'"
}
}
],
"WriteTo": [
{
"Name": "Async", //i use async plugin from serilog
"Args": {
"configure": [
{
"Name": "File",
"Args": {
"path": "Logs/Log_.txt",
"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog",
"rollingInterval": "Day",
"retainedFileCountLimit": 7
}
}
]
}
}
]
}
}
},
通过配置文件进行记录器设置的文档很少。任何人都可以帮忙 - 只是使用记录器设置的示例。在示例中 - 所有日志都写入一个sample.txt。记录对某个 API / api/health 的调用 - 在单独的文件中，并且不包含在 example.txt 中。示例广告 - IMyLogger - 写入单独的 SampleMy.txt。您可以添加多个部分，并按不同的条件划分日志。最好将本地日志记录级别设置为最低，它们将被全局级别覆盖。全局过滤器将排除来自所有子记录器的日志（我不使用它）。 PS抱歉英语不好）

我从我发现的博客中得到了一个很酷的解决方案。它确实表现得很有魅力。如果发生任何问题请告诉我。我还与大家分享博客https://www.techrepository.in/blog/posts/writing-logs-to- Different-files-serilog-asp-net-core。另外，为了过滤日志，您需要使用 Serilog.Eexpressions nuget 包。 希望你能从这里得到你想要的东西
"Serilog": {
"Using": [ "Serilog.Sinks.File", "Serilog.Expressions" ],
"MinimumLevel": {
"Default": "Debug"
},
"WriteTo": [
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByIncludingOnly",
"Args": {
"expression": "@l = 'Error' or @l = 'Fatal' or @l = 'Warning'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "../logs/error_.log",
"outputTemplate": "{Timestamp:o} [{Level:u3}] ({SourceContext}) {Message}{NewLine}{Exception}",
"rollingInterval": "Day"
}
}
]
}
}
},
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByIncludingOnly",
"Args": {
"expression": "@l = 'Information' or @l = 'Debug'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "../logs/debug_.log",
"outputTemplate": "{Timestamp:o} [{Level:u3}] ({SourceContext}) {Message}{NewLine}{Exception}",
"rollingInterval": "Day"
}
}
]
}
}
}
]},
第 1 步：安装所需的软件包
确保您安装了必要的 Serilog 软件包。您将需要：
SerilogSerilog.Sinks.FileSerilog.Expressions
说明：
SerilogUsingMinimumLevelWriteToErrorFatalWarningerror_.logInformationDebugdebug_.logFilterWriteTo我对这个问题做了一些测试。好消息是您的配置有效。您的错误文件可能未创建，因为没有记录错误。
Serilog 将在第一条消息记录到该文件时创建日志文件。如果您运行这个简单的程序并（取消）注释错误记录，您可以确认这一点。
class Program
{
static void Main(string[] args)
{
var errorLogConfiguration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("settings.json", optional: false, reloadOnChange: true)
.Build();
var log = new LoggerConfiguration()
.ReadFrom
.Configuration(errorLogConfiguration)
.CreateLogger();
log.Warning("Warning");
log.Error("Error");
}
}
