File Logging

[alexrohozneanu]

Does OPA support logging in files on disk alongside file rotation and retention?

Hi @alexrohozneanu!

We don't have native support for logging to a file in OPA.

Generally in Cloud Native environments logging to a file is discouraged, testing my knowledge here a bit but I think the ideas grew out of things like the 12 factor app: https://12factor.net/logs.

Is there a reason you need to have a log file stored on OPA's host?

Thanks for the response, @charlieegan3!

In my case I run OPA on a windows machine, and I don't want to use Docker for that due to performance issues, I run it as a standalone process.

I would like to have log files on the OPA's host for testing purposes, I want to aggregate once in a while the decisions that were made, based on the policies that I defined, to see if they need improvements or not.

Ok cool, I suppose in this case it might make sense to enable console decision logging and then just redirect the stderr and stdout to the file you need.

Yeah...I was a little lazy to do that 😂 that's why I asked. Thank you!

No problem, sorry to not have a better option for you!
