Log Files Names Mapping using variables

You can use variables to define the log file path and files names in the FastTransfer_settings.json In the WriteTo array you can use a Map like that :

{
  "WriteTo": [
      {
        "Name": "Console",
        "Args": {
          "outputTemplate": "{Timestamp:yyyy-MM-ddTHH:mm:ss.fff zzz} -|- {Application} -|- {runid} -|- {Level:u12} -|- {fulltargetname} -|- {Message}{NewLine}{Exception}"
        }
      },
      {
        "Name": "Map",
        "Args": {
          "keyPropertyName": "TraceId",
          "defaultKey": "no-trace",
          "to": [
            {
              "Name": "File",
              "Args": {
                "path": "/logs/{logdate}/{sourcedatabase}/{sourcetable}/FastTransfer-log-{filename}-{logtimestamp}-{traceid}.json",
                "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact",
                "rollingInterval": "Infinite",
                "shared": false,
                "encoding": "utf-8",
                "retainedFileCountLimit": 100
              }
            }
          ]
        }
      }
    ]
}

The available variables to customize log path or log filename are :

Variable Name	Description
{logdate}	Current date in yyyy-MM-dd format
{logtimestamp}	Timestamp of the log entry
{sourcedatabase}	Name of the source database
{sourceschema}	Name of the source schema
{sourcetable}	Name of the source table
{filename}	Name of the file being processed
{runid}	Run identifier provided in the command line
{traceid}	Unique identifier generate at runtime
