supplying an
ExpressionTemplatefor that argument, from https://github.com/serilog/serilog-expressions, will allow you to customize the JSON in whatever way you require
(examples are currently thin on the ground, but should be enough in the Serilog.Expressions readme to get you started)
if you were keen to implement it in your own app, you could do it in two parts
- create some marker type
class FromContext { }
Destructure.AsScalar<FromContext>()
- create
class RemoveFromContextEnricher: ILogEventEnricherthat removes any property with a scalar value of typeFromContext
Enrich.With<RemoveFromContextEnricher>as the first enricher
log.Information("{Alpha} bit of {Bravo} before {Charlie}", "A", new FromContext(), "details");
I think that will do it; there may be other ways to make it work :-)
@nblumhardt Hey! I really appreciate you sharing this!
What got me started down this path is that I had taken the time to integrate Serilog with SimpleInjector, using this solution so that SimpleInjector could ensure a Serilog context was established as a "unit of work" for each CQRS command I process. The intent is that any plugin in my plugin-architecture will create log entries that already have the name of the plugin mentioned in each log entry (and available as one of the properties). I got it all working, but discovered that simply having the "ForContext" set correctly for each plugin...didn't mean that I could cleanly integrate that into the text of the log entries.

@nblumhardt Thank you so much, Nicholas. Worked like a charm 👍 BTW, what do you think about sink developers like us taking the build system in another direction? We use GitHub Actions to build everything open source now, why entering the build system in our sink feels like entering another world. I can see advantages in all sinks using the same overall tech stack and scripts, though. What do you think?
@nblumhardt are you able to offer advice on porting from Serilog.Filters.Expressions to Serilog.Expressions for the RAW API as I noticed the former is now deprecated.
I was try but no events comes from.
.MinimumLevel.Override("Microsoft.Data.SqlClient.EventSource", LogEventLevel.Verbose)
@warrenbuckley I think this is the method you want:
have been giving some thought lately to the names of built-in props -
@l vs @Level etc. - would you use a hook point to switch back to the earlier names, if we add one, or do you prefer the shorter ones
?
@nblumhardt If we end up moving the sink to our organization (hadn't heard that was on the table), I'm pretty sure we want to move to GitHub Actions then. The important thing around moving sinks out of the Serilog org is that we would still have a NuGet API key to be able to publish this with a
Serilog.Sinks.* prefix on NuGet 👍 I would definitely prefer having more control over the repository.

How can I use Enrich property with structured data logging?
var sensorInput = new { Latitude = 25, Longitude = 134 };
Log.Information(" Processing {@SensorInput} for {ProcessName}", sensorInput);
gives me: System.IndexOutOfRangeException: Index was outside the bounds of the array. at Microsoft.Extensions.Logging.LogValuesFormatter.GetValue(Object[] values, Int32 index)Log.Information(" Processing {@SensorInput}", sensorInput);
and
Log.Information(" Processing for {ProcessName}");
Works good.I have an odd problem though. In an AspNetCore app the following code in CreateHostBuilder appears in KibanaLog.Information("Starting app");
But the following code in a method on my controller does notLog.Information("Requested data");
Does anyone have any idea why?
Any ideas how I can achieve my goal to add ServiceBus.Message.CorrelationId to my logs automatically using Enrich.With?

In ETW there is a concept of publish subscribe where if there is no listener to an event then the logging code has almost no performance effect on the application. The listener can be separate from the application too. From my quick read Serilog doesn't have the same concept, there is an event processor integrated into the application that will send the event to sinks. Am I correct?
@varunkumarmnnit I'd say this is not a common ask, nor necessarily a good idea - if you compress the file folder you can achieve similar compression. I'd be more concerned about having logs in a central location etc - i.e. the log files for me are just a temporary landing zone on the way to being forwarded to a log store etc. Finally, I'd say the best place to ask things like this is StackOverflow.com - there's a much higher level of traffic, and anyone that's going to have time to help you here will also be looking at questions tagged

Hi there. I need to log the json of some objects such that the json can be copied and used as input to an api. But I need it to be proper json, and specifically what I would get if I used Newtonsoft.Json.JsonConvert.SerializeObject. Serializing this way takes into account Newtonsoft attributes on property names like JsonProperty (which you can use to change the property's name) and JsonIgnore. (which you can use to omit the property from the serialized string). Right now I log this way (below) to achieve this, but I would prefer to make some sort of serilog extension instead. I was thinking maybe I could do it with a DestructuringPolicy? Anyway I'd appreciate any advice.
_logger.LogInformation($"{nameof(my Object)}:{Newtonsoft.Json.JsonConvert.SerializeObject(myObject)}");
_logger.LogInformation($"{nameof(my Object)}:{Newtonsoft.Json.JsonConvert.SerializeObject(myObject)}");
In a perfect world I would love to be able to just use a different destructuring token, say "#" to indicate I want the "myObject" to be serialized this way. So I could choose "@" or "#" as needed. But I would settle for having this sort of serialization be the default for a sink.
It looks like this but I which it'd be the reverse:
