Hi,

I'm seeing many errors for Diskstat Windows with the error message `Could not return any performance counter values for \\.\K: .Error: Incorrect function.`

I'm using Elastic Agent with Windows integration. My question is: Is there a way for me to add config (In kibana agent config) to ignore disk io stat for K-drive? This is a special device that does not support these metrics.

I don't see an option for "additional yaml" or similar

Many thanks!

Solved. Add these two types in the field `List of filesystem types to ignore`

- unavailable
- unknown

As options to the integration for system under: Collect metrics from System instances :

- System filesystem metrics
- System fsstat metrics
