Sample query
In the user tenant, query the RPC requests received by the current tenant on all nodes, and check which requests have a waiting time in the queue greater than 1 second.
obclient [oceanbase]> SELECT * FROM oceanbase.GV$OB_RPC_INCOMING WHERE QUEUE_TIME > 1000000;
The query result is as follows:
