How can I dynamically set a "logLevel" variable used during logging?

[kurtkanaskie]

I want to control logging levels (e.g. INFO, ERROR, DEBUG) interactively such that I can change them on the fly and have my logging policy (JavaScript) add additional content to the log messages. I want this to happen in a "timely" manner.

I'm setting the "logLevel" value in a KVM per proxy. I know from docs that the KVM cache is not cleared when updating the KVM in the UI or management API.

So, there are a few options:

1. Set the "ExpiryTimeInSecs" to a low enough value to be "timely" (e.g. 30), and change the value in the UI or Management API, but there is a tradeoff on performance.
2. Use a special built API proxy that uses the KVM policy to PUT the value as suggested here, but that seems contrived.

What other options are there?

Use KVM,

Keep interval small.

Validate your concerns about "tradeoff on performance" in practice.

I'll bet it won't be extravagant.
