Disable downwardMetrics feature gate

MediumLevel 1Automatedopenshift-virt

Description

The downwardMetrics feature allows users to collect and monitor additional metrics related to host and virtual machine performance. Audit: Passes when .spec.featureGates.downwardMetrics is false or unset (the default is disabled). Requires oc logged in to the cluster with read access.

How it is checked

Audit method: Shell command

shell

command -v oc >/dev/null 2>&1 || exit 1; v=$(oc get hyperconverged kubevirt-hyperconverged -n openshift-cnv -o jsonpath='{.spec.featureGates.downwardMetrics}') || exit 1; [ "$v" = true ] && echo noncompliant || echo compliant

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Set downwardMetrics to False $ oc patch hyperconverged kubevirt-hyperconverged - n openshift - cnv --type='json' -p='[ {"op": "replace", "path": "/spec/featureGates/downwardMetrics", "value": false }, ]'
