Suppress nil value error in application insight scaler

[kia69028]

Proposal

Hi team,

I would like to have the option to suppress the error of reading nil value as reading 0 in using application insights.

Use-Case

My use case is as follows:

I have a metric which only logs when there are incoming requests to the service. During the period of no requests, there will be no metrics. This caused the issue that over a time span with no activity, I am reading nil value over that metric, and this will put the scaled object into fallback (which I do not want) and flood the keda operator logs with error logs.

It would be great if there is an option to ignore the nil value error.

Is this a feature you are interested in implementing yourself?

No

Anything else?

Hi @kia69028
In prometheus Scaler, we have an option to treat nil as zero (returning 0 when nil is returned). Could this be enough for your use case?

Hi @JorTurFer

Thank you for your replay. I saw that option in prometheus Scaler, and yes this is exactly what I want.
However, the issue is that I am using azure application insight scaler, which does not support this feature at the moment.
Therefore, I would want to know if there is any work around possible in azure application insight scaler.

Thank you!

IMHO it is not, but we are open to contributions. It's quite easy task, you can take inspiration from the Prom scaler.
