As per documentation you can change the agent name using annotation, however, if the annotation includes a forward slash (/) the k8s_replicaset_annotations_key resolution doesn't work as expected
Example:
Annotations: abc/asset-tag: lab
abc/cluster-id: zone
DXO2
The issue is related to defect # DE662549 to be fixed in 26.2.1. For an update contact Broadcom Support
Workaround: do not use forward slash (/) in the annotations.
