Serilog:如何进一步增强 appsettings.json 中的过滤器表达式? [英] Serilog: How do I further enhance a filter expression in appsettings.json?
问题描述
我有两个带有 Serilog 的记录器，它们保存到不同的文件中.我想通过 appsettings.json 而不是代码创建记录器.
I have two loggers with Serilog and they save to different files. I want to create the loggers through the appsettings.json as opposed to code.
当我通过 Startup.cs 配置创建我的记录器时，我得到了一个更具体的日志，我更喜欢这样，因为它更清晰，并允许其他人检查日志和无需太多技术知识即可了解正在发生的事情.但是，我想将其应用于 appsettings，以便我可以将代码迁移到我可能使用的任何其他项目.仅供参考:我不想覆盖日志级别.
When I create my loggers through the Startup.cs configuration, I get a much more specific log and I prefer to have it that way as it's much clearer and will allow others to check the logs and understand what's going on without needing much technical knowledge. However, I want to apply this to the appsettings so that I can migrate the code to any other project that I may use.
FYI: I don't want to override the log level.
例如，我使用代码创建记录器，如下所示:
For example, with code I create my loggers like so:
Log.Logger = new LoggerConfiguration()
.WriteTo.ColoredConsole()
.WriteTo.Logger(lc => lc
.Filter.ByExcluding(Matching.FromSource("Microsoft"))
.WriteTo.File("Serilogs/Program_log_.txt", rollingInterval: RollingInterval.Day)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information))
.WriteTo.Logger(lc => lc
.Filter.ByIncludingOnly(Matching.FromSource("Microsoft"))
.WriteTo.File("Serilogs/ServerTrace_log_.txt", rollingInterval: RollingInterval.Day)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information))
.CreateLogger();
这会生成我喜欢的两个单独的输出:文件 1:可读的自定义日志:
This generates the two separate outputs that I like the formatting of:
File 1: Readable, custom logs:
2019-01-18 11:18:09.873 +00:00 [INF] //Some custom log information
2019-01-18 11:18:09.875 +00:00 [INF] //Some more custom log information
File 2:堆栈跟踪，服务器信息:
File 2: Stack trace, server information:
2019-01-18 11:17:56.378 +00:00 [INF] User profile is available. Using '//A path' as key repository and Windows DPAPI to encrypt keys at rest.

当我使用 JSON appsettings 时，它看起来像这样:
When I do it by using the JSON appsettings it looks like so:
"Serilog": {
"Using": [
"Serilog.Sinks.File",
"Serilog.Filters.Expressions",
"Serilog.Settings.Configuration"
],
"WriteTo": [
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByIncluding",
"Args": {
"expression": "SourceContext = 'Microsoft'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "./Serilogs/server_logs_.log",
"rollingInterval": "Day"
}
}
]
}
}
},
{
"Name": "Logger",
"Args": {
"configureLogger": {
"Filter": [
{
"Name": "ByExcluding",
"Args": {
"expression": "SourceContext = 'Microsoft.AspNetCore.Hosting.Internal.WebHost'"
}
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "./Serilogs/program_logs_.log",
"rollingInterval": "Day"
}
}
]
}
}
}
]
}
这会生成两个文件.文件 1:可读的自定义日志:
And this generates the two files.
File 1: Readable, custom logs:

因此，通过应用感觉相同的技术，结果的结果是不同的，因为 File 1 现在包含更多动作信息，而 File 2 包含堆栈 加上自定义日志信息，尽管我希望它们完全分开.
So, by applying what feels the same technique, the outcome of the results are different as File 1 now contains more action information and File 2 contains the stack plus the custom log information although I want them completely separate.
推荐答案
我认为您的过滤器不太正确.
I think your filters are not quite right.
过滤器表达式应该是:
"expression": "SourceContext = 'Microsoft' or StartsWith(SourceContext, 'Microsoft.')"
(我猜你可以在没有最后一个点的情况下执行 StartsWith(SourceContext, 'Microsoft') ，但是对于像 MicrosoftOrIsItReally.MyNamespace 这样的命名空间，这可能无法正常运行)
(I guess you could just do StartsWith(SourceContext, 'Microsoft') without the last dot , but then that may not behave properly for namespaces like MicrosoftOrIsItReally.MyNamespace)
(在内部 Matching.ForSource 执行 SourceContext.StartsWith(..) 类型的过滤，如在源代码中)
(internally Matching.ForSource does a SourceContext.StartsWith(..) kind of filtering , as seen in the source)
要确认，您可能需要编辑文件接收器的 outputTemplate 以显示 SourceContext 属性并查看日志事件的来源.(默认为 "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}").您可以将其更改为 "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}]<{SourceContext}> {Message:lj}{NewLine}{Exception}" 以包含 SourceContext 属性.
To confirm it, you may want to edit the outputTemplate of your File sink to display the SourceContext property and see the origin of the log events. (the default is "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}") . You could change it to "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}]<{SourceContext}> {Message:lj}{NewLine}{Exception}" to include the SourceContext property.
顺便说一下，您有一个额外的、不需要的 "Using" 指令."Serilog.Settings.Configuration" 不是必需的
By the way, you have an extra, unneeded "Using" directive. The "Serilog.Settings.Configuration" is not necessary
