- `gateway_<gateway_type>_bytes_received`: Total number of bytes received from cloud backend (in GET & HEAD Requests).
|
||||
`<gateway_type>` changes based on the gateway in use can be 's3', 'gcs' or 'azure'. Other metrics are labeled with `method` that identifies HTTP GET, HEAD, PUT and POST requests to the backend.
