com.linkedin.davinci.stats.ServerMetadataServiceStats

public class ServerMetadataServiceStats
extends AbstractVeniceStats

Stats for server metadata service endpoints.

Recording design:

• invoke_count: Tehuti-only (total requests). OTel invoke count is derivable as success + failure.
• success_count: OTel-only (per-store, per-cluster).
• failure_count: Tehuti + OTel (dual-recorded).

recordRequestBasedMetadataSuccessCount

public void recordRequestBasedMetadataSuccessCount(String storeName)

recordRequestBasedMetadataFailureCount

public void recordRequestBasedMetadataFailureCount(String storeName,
 Exception e)

Records failure. Uses OpenTelemetryMetricsSetup.UNKNOWN_STORE_NAME when the exception indicates the store doesn't exist, to bound per-store OTel cardinality from arbitrary request-provided names.
