I am trying to make a customized json log output using Serilog Expressions Format. I am using below template :
"template": "{{"Time": "{@t:yyyy-MM-ddTHH:mm:ss.fffffffzzz}", "Level": "{@l}", "Event": "{@m}" {#if TraceId is not null}(, "TraceId": "{@tr}" ){#end} "context": {@p} , "exception":"{@x}"}}n"
In this template every runs fine except when I have an exception logged, In that case due to multiline exceptions it is breaking the json. I have fixed it with an enricher
using Serilog.Core;
using Serilog.Events;
using System;
namespace CatalogService.Common.Enricher
{
public class CustomLogEnricher : ILogEventEnricher
{
public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
{
//Enrich Exception (single line)
if (logEvent?.Exception != null)
{
string? formattedException = logEvent.Exception.ToString().Replace(Environment.NewLine, "\n");
logEvent.RemovePropertyIfPresent("Exception");
logEvent.AddPropertyIfAbsent(propertyFactory.CreateProperty("Exception", formattedException));
}
}
}
}
Now this enricher pushes the exception in log @p, due to this either exception are repeated in both @p and @p[‘Exception’] Since I want this exception to be in root of the json.
Please help I need a simple log in following format:
{
"time": Timestamp,
"level": Level,
"event": Message(Rendered),
"exception": exception if any,
"context": @p (Rest of the properties)
}
I am expecting the json in following format:
{
"time": Timestamp,
"level": Level,
"event": Message(Rendered),
"exception": exception if any,
"context": @p (Rest of the properties)
}
I have tried using JsonFormat, CompactJsonFormat, Rendered Json Format but they don’t offer customization.
I have tried above Expression approach along with Enricher, which mostly works except for the exception appearing twice once in @p and then in @p[‘Exception’]
