* feat(metrics): add task completion latency tracking and detailed metrics reporting - Add histogram metric for tracking transfer task completion latency with configurable buckets - Record task start time in submitTransfer and calculate latency upon completion - Enhance metrics reporting thread to include latency distribution statistics - Add skip_metrics parameter to getBatchTransferStatus to avoid double counting - Update task structure to include start_time field for latency calculation Signed-off-by: staryxchen <staryxchen@tencent.com> * feat: add metrics support for submitTransferWithNotify Signed-off-by: staryxchen <staryxchen@tencent.com> * refactor(metrics): improve metrics recording logic with early returns - Replace nested if statements with early returns using goto for cleaner flow - Add boundary checks for task_id and validate start_time before recording - Only record metrics for COMPLETED status and reset start_time to prevent duplicates Signed-off-by: staryxchen <staryxchen@tencent.com> * refactor(metrics): simplify bucket count tracking logic - Remove conditional checks for vector bounds by ensuring prev_bucket_counts_ size matches bucket_counts - Consolidate previous snapshot update into a single assignment Signed-off-by: staryxchen <staryxchen@tencent.com> * fix(metrics): conditionally enable metrics collection - Add metrics_enabled_ flag check before collecting metrics - Wrap metrics collection logic with flag condition to avoid unnecessary operations - Ensure metrics are only recorded when explicitly enabled Signed-off-by: staryxchen <staryxchen@tencent.com> * docs: clarify Transfer Engine metrics limitation with TENT - Add note about MC_TE_METRIC not being supported when using Transfer Engine TENT in deployment guide - Add same note to Python API reference for MC_TE_METRIC environment variable Signed-off-by: staryxchen <staryxchen@tencent.com> --------- Signed-off-by: staryxchen <staryxchen@tencent.com> |
