VWLOG
Instead of creating an error log configuration file, you can configure Vector logging by specifying the VWLOG environment variable before Vector is started.
The following results in INFO-level logging that is written to the file /tmp/vectorwise.log:
Linux:
export VWLOG="default=info:file,filename=/tmp/vectorwise.log,file=timestamp:showlevel:flush:pid"
Windows:
SET VWLOG="default=info:file,filename=C:\temp\vectorwise.log,file=timestamp:showlevel:flush:pid"
