Disable debug logging of Quartz.Net in an ASP.NET Core app

Question

Using Quartz.Net 3.1.3 with an ASP.NET Core app using Serilog and I'm trying to disable debug logging of quartz because it spams the logs in a production environment.

I'm setting the following in appsettings.json:

"Logging": {
    "LogLevel": {
      "System": "Warning",
      "Microsoft": "Warning",
      "MyCompanyNameSpace": "Information",
      "Quartz": "Warning"
    }
},

but I can still see that is logging:

2021-11-02 09:49:34.025 +02:00 [DBG] Calling Execute on job MyCompany.SyncJobGroup.SyncJobA
2021-11-02 09:49:34.154 +02:00 [DBG] Trigger instruction : DeleteTrigger
2021-11-02 09:49:34.154 +02:00 [DBG] Deleting trigger

How can I disable it?

You can see a specific case of the same being done here: https://stackoverflow.com/questions/877217/turn-off-debug-logging-in-quartz-net/7973019 — T. Nielsen, Nov 02 '21 at 08:36

The solution has two parts:

1.The following Serilog configuration is missing from appsettings.json to define the correct logging level for Quartz:

https://groups.google.com/forum/#!topic/quartznet/Cjco_Ob9yrM

"MinimumLevel": {
  "Default": "Debug",
  "Override": {
    "Microsoft": "Warning",
    "System": "Warning",
    "Quartz": "Warning"
  }
},

The configuration of "Quartz": "Warning" suppressed the Debug "Batch acquisition" messages from being logged.

And

2 - The invocation of both the SerilogLogger.Reconfigure and SerilogLogger.RefineConfiguration methods was completely unnecessary. I removed this. It was overwriting the config from point 1) above. All Serilog configuration should take place in my appsettings.
