### Log sanitization
{{< feature-state for_k8s_version="v1.20" state="alpha" >}}
{{<warning >}}
Log sanitization might incur significant computation overhead and therefore should not be enabled in production.
{{< /warning >}}
The `--experimental-logging-sanitization` flag enables the klog sanitization filter.
If enabled all log arguments are inspected for fields tagged as sensitive data (e.g. passwords, keys, tokens) and logging of these fields will be prevented.
List of components currently supporting log sanitization:
* kube-controller-manager
* kube-apiserver
* kube-scheduler
* kubelet
{{< note >}}
The Log sanitization filter does not prevent user workload logs from leaking sensitive data.

The `-v` flag controls log verbosity. Increasing the value increases the number of logged events. Decreasing the value decreases the number of logged events. The `-v` flag controls log verbosity.
