metrics-apiserver json logs

[naseemkullah]

    > I'm very sorry @JorTurFer - I was looking at logs from the `keda-operator-metrics-apiserver` deployment. It seems that only has a level setting as opposed to the operator having level, format, and timeEncoding.

Our logs for keda-operator are correctly being emitted as JSON 🤦

That said, I'd like to have the metrics-apiserver log in json format as well, primarily because all info logs are emitted to stderr and those show up as error logs in our logging system. Could this functionality please be added?

Hi,
What KEDA version are you using?

[naseemkullah]

Hi Jorge, 2.9.1

[JorTurFer]

I have reviewed and you are right, all the logs are sent to stderr :( You can disable this behaviour removing the -logtostderr=true from the deployment arguments.
Maybe we should review this in the future @kedacore/keda-core-contributors , something like -stderrthreshold=ERROR could be enough

Hi there, this is still an issue in 2.10.1. metrics server has a different logging settings than the other two binaries, as visible in the docs of helm: https://github.com/kedacore/charts/blob/main/keda/README.md. This doesn't allow users to enable json logs or set a logging level using words (like debug or info).

Are there any plans to change this? It's hard to tell from the issue history.

[JorTurFer]

AFAIK, there isn't work in progress in this direction, but if you have an idea and you are willing to contribute, you can do it :)

I just want to contribute .

[JorTurFer]

There isn't any wip about this, so the stage is yours 😄

json logging would be great!

BTW Why is this issue closed?

[omBratteng]

Would love JSON logs so that they can be properly parsed in places like Google Cloud Logs Explorer.
