Sitecore experience commerce 9 – No Sitecore Commerce Engine log files?

Recently while working with Sitecore experience commerce 9, I’d encountered few issues. To resolve those issue, I need to check logs. While troubleshooting I have found that there were no Sitecore commerce engine log files in log folder. I’d recycle application pool and even restarted IIS but no luck. I’d started troubleshooting with config. json file located at C:\inetpub\wwwroot\CommerceAuthoring_Sc9\wwwroot\ and Bingo! I’d hit the nail right on the head. I’ve compared config.json with default Sitecore.Commerce.Engine config.json file and found out that logging configuration section was missing in config.json. I’ve added below configuration in config.json, given write access on log folder to NetworkService account and application pool identity user (CSFndRuntimeUser), restarted IIS and log files started updating in log folder. I’ve done similar steps for CommerceMinions, CommerceOps and CommerceShops websites.

"Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Information",
      "System": "Warning",
      "Microsoft": "Warning"
    },
    "ApplicationInsightsLoggingEnabled": false
  },
  "Serilog": {
    "Using":  ["Serilog.Sinks.Literate", "Serilog.Sinks.File"],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Information",
        "System": "Information"
      }
    },
    "FileSizeLimitBytes": 100000000
  }

Comments and suggestions are most welcome. Happy coding!
