Power BI Log Files

[guruprasathb]

There are quite few logs are generated by Power BI Services in the following folder (C:\Program Files\Microsoft Power BI Report Server\PBIRS\LogFiles). Is it possible to change the log file path? Thanks,

You can set it on the "C:\Program Files\Microsoft Power BI Report Server\PBIRS\RSHostingService\config.json" file, changing the properties bellow for each executable:
"Logger.path": "..\\LogFiles\\",
"Dumper.path": "..\\LogFiles\\",

Please create a safe copy of this file bofore any change.

I was not able to find any official documentation regarding to this procedure. That would be nice if someone can complement the answer with a reference.

Hi,

I tried changing the value in config.json file and restarted the service. But it still creating in C:\ only.

"Logger.path": "E:\\LogFiles\\",
            "Dumper.path": "E:\\LogFiles\\",

Kindly advice.

Thanks,

Just noted this property in config.json file but still no luck.

"restartOnChangesTo": "Dumper.flags,Dumper.path,Dumper.preventIfContains,listenerUrl,Logger.path"

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-lo...

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",
