LMV_TRACE_EVENTS

Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

Although the monitoring service queries the sharded MV_TRACE_EVENTS view, the individual nodes' LMV_TRACE_EVENTS views are also available. Querying the LMVs individually is more performant than querying the sharded MV.
