Only counted when the starlet readiness check passes and the RPC is actually dispatched; starlet-not-ready timeouts are not included. Should normally be near zero. A sustained or rising rate is a strong signal that FE-side task or node selection is scheduling work on a BE that does not yet have the shard, or that shard push propagation from FE is lagging. Recommended alert: high per-BE rate over a 5-minute window.

`starrocks_be_staros_shard_info_fallback_failed_total`

Description: Indicates the end time of the last query or loading under the specific warehouse. For a shared-nothing cluster, this item only monitors the default warehouse.

`starrocks_fe_max_journal_replay_lag`

Unit: Count
Type: Instantaneous
Description: The largest number of metadata journals that any alive Follower or Observer FE still has to replay to catch up with the Leader. Reported only by the Leader FE (is_leader="true"), which is the only node that knows both its own journal write position and, through heartbeats, every other node's replayed journal ID. FE nodes that are not alive are excluded, because the journal ID they last reported is frozen at their final successful heartbeat; use the Alive column of SHOW FRONTENDS to detect those instead. It returns 0 when every other node has caught up, when no other FE node is alive, and on a single-FE cluster. A high or continuously growing value means metadata replay on at least one node is falling behind, which causes that node to serve stale metadata and, once meta_delay_toleration_second is exceeded, to forward its queries to the Leader.

`starrocks_fe_memory_usage`

Unit: Bytes or Count
Type: Instantaneous
Description: Indicates the memory statistics for various modules under the specific warehouse. For a shared-nothing cluster, this item only monitors the default warehouse.

The following metrics are summary-type metrics that provide latency distributions for different phases of a transaction. These metrics are reported exclusively by the Leader FE node.

Each metric includes the following outputs:

Quantiles: Latency values at different percentile boundaries. These are exposed via the quantile label, which can have values of 0.75, 0.95, 0.98, 0.99, and 0.999.
<metric_name>_sum: The total cumulative time spent in this phase, for example, starrocks_fe_txn_total_latency_ms_sum.

All transaction metrics share the following labels:

type: Categorizes transactions by their load job source type (for example, all, stream_load, routine_load). This allows for monitoring both overall transaction performance and the performance of specific load types. The reported groups can be configured via the FE parameter txn_latency_metric_report_groups.

`starrocks_fe_slow_lock_held_time_ms`

Unit: ms
Type: Summary
Description: Histogram tracking the lock held time (in milliseconds) when slow locks are detected.

Description: The longest time, in milliseconds, that a transaction is currently sitting in the COMMITTED status pending publish to VISIBLE, that is, the age of the oldest committed-but-not-yet-published transaction. Unlike starrocks_fe_txn_publish_* metrics, which are summaries recorded after a transaction finishes, this is a live gauge of the worst-case in-flight wait. The value is reported per database via the db label and only by the Leader FE node (is_leader="true"). It returns 0 when no committed transaction is pending publish. A high or continuously growing value indicates that version publishing is stuck or lagging behind commits.

`starrocks_fe_txn_publish_ack_latency_ms`

Unit: ms
Type: Summary
