Descrizione
Title: Invalid metric format emitted for stats where to-zone/from-zone is empty
Description:
What issue is being seen? Describe what should be happening instead of the bug, for example: Envoy should not crash, the expected value isn't returned, etc.
Stats are being emitted from Envoy with consecutive .. between namespaces due to empty to-zone,
for example:
cluster.egress_dynamodb_iad.zone.1a..upstream_rq_2xx
Repro steps:
Include sample requests, environment, etc. All data and inputs required to reproduce the bug.
Do not specify an AZ for an upstream cluster. Inspect the AZ-AZ stats via curl on admin.
Admin and Stats Output:
Include the admin output for the following endpoints: /stats, /clusters, /routes, /server_info. For more information, refer to the admin endpoint documentation.
