Configure source and jsonFormatter in appsettings.json

[agilenut]

I'd like to configure the source and a custom jsonFormatter, such as the CompactSplunkJsonFormatter, in appsettings.json. I've been able to do one or the other but not both. I'm assuming this is because the overloads that accept a jsonFormatter expect you to pass the source into the formatter instead of into the sink. Is there some kind of appsettings.json syntax to make this work? If not, is there some enhancement you can think of that would make this work?

I figured it out.

I had tried something like this earlier based on this documentation

{
    "Serilog": {
        "WriteTo": [{
            "Name": "EventCollector",
            "Args": {
                "splunkHost": "https://my-host.splunkcloud.com",
                "eventCollectorToken": "my-token",
                "jsonFormatter": {
                    "type": "Serilog.Sinks.Splunk.CompactSplunkJsonFormatter, Serilog.Sinks.Splunk",
                    "source": "my-source"
                } 
            }
        }]
    }
}

It turns out I had to update Serilog.Settings.Configuration to 3.3.0. I was using 3.1.0 because that is what was pulled in by Serilog.AspNetCore 4.1.0 (currently latest stable).

Maybe this helps someone else.
