I add DaskAutoscaller object and now I see a lot of Kubernetes events

[yovio-rca]

I've seen a lot of Timer 'daskautoscaler_adapt' succeeded events generated by DaskAutoscaller.

The events generated by kopf timer.

Is there a way to tune down this event logging?

I've had a look through the kopf docs and I can't see an obvious way to configure handler events. I've opened nolar/kopf#1170 to ask there

[yovio-rca]

Actually there is, look at this: https://kopf.readthedocs.io/en/stable/configuration/#logging-events

If somehow we can link up Environment variable to set these 2 settings, settings.posting.level and settings.posting.enabled, it will give us a way to configure the level as needed or disable it altogether.

I believe a minor change here:

dask-kubernetes/dask_kubernetes/operator/controller/controller.py

Line 283 in 75fe3b9

@kopf.on.startup()

Changing timer frequency probably not the best solution, too low, it will make AutoScaller not agile, too high causing lots of events.

In my opinion, we should just control which logging message goes to events. Normally events just for important stuff, so I'm okay with Warning and error only.

If user can control the level, it will be the best.

I'm surprised that kopf doesnt allow controlling settings from yaml file. If setting can be controlled by yaml file, we can have yaml filed mapped to configMap.

I raised this question to kopf team: nolar/kopf#1171

[jacobtomlinson]

Yeah good point. Thanks for pointing out the kopf docs page. I've opened #946 which allows setting these options via the Dask config system.
