我正在尝试配置serilog以写入多个文件，没有任何运气。 使用这种配置，它只是写入第二个文件吗？
{
"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appsettings.json中具有不同配置的软件中。像这样吗？
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();

经过一段时间的错误后，由于缺乏有关Serilog的文档，我的发现重试并几乎放弃了。他们在GitHub上工作：https://github.com/serilog/serilog-filters-expressions/issues/27。几乎每个线程都会得出与必须创建SUBLOGGER相同的结论。这是我的实现。为此，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
}
}
]
}
}
]
}
}
},

我找到了解决方案。为appsettings.json，ErrorLog和AuditLog创建了单独的部分。
ash现在我可以创建2个单独的记录器：
bash哪个更适合我的需求。

我对此问题进行了一些测试。好消息是您的配置有效。您的错误文件可能未创建，因为未记录任何错误。
当第一条消息记录到该文件时，Serilog将创建日志文件。如果您运行此简单程序并取消注释错误记录，则可以确认这一点。
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");
}
}

关于通过配置文件进行的记录器设置的文档很少。任何人都可以帮忙-这只是使用记录仪设置的一个示例。在示例中-所有日志都写在一个sample.txt中。在一个单独的文件中登录某个API / api / health的调用，并且不包含在sample.txt中。还有一个示例广告-IMyLogger-写入单独的SampleMy.txt。您可以添加许多部分，然后按不同条件划分日志。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。全局过滤器将从所有子记录器中排除日志（我不使用它）。 PS对不起，英语不好）

由于简单的Serilog文档和任何接收器而苦苦挣扎了几天，这终于对我有用，而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"
}
}
]
}
}
}
希望这可以帮助任何人！
