Power BI Log Files

PBIRS does maintain backward compatibility with older versions of SSRS, so this will still work: https://docs.microsoft.com/en-us/sql/reporting-services/report-server/report-server-service-trace-log?view=sql-server-2017

Having said that, the config in config.json should overlay that legacy config.  One thing to note about the config.json is that it is hierarchical.  So if you'd like to configure all processes to log to the same directory, it's best to do it in the top level config section, and then you can override that setting at the per-process level if necessary.

As an example, here's the first few lines of a config.json file that sets all of the processes' loggers to the c:\temp\logs directory:

{
    "Config":
    {
        "Logger.path": "C:\\temp\\logs\\",
        "Dumper.path": "C:\\temp\\logs\\",
        "ASPort": "5132",
