查询 SQL 流量分布情况及 QPS 
=======================================



运行如下语句可以查询 SQL 流量分布情况及 QPS：

```sql
obclient>SELECT/*+ PARALLEL(15)*/t2.zone, t1.svr_ip,  COUNT(*) AS RPC_COUNT,
AVG(t1.elapsed_time), AVG(t1.queue_time)  
FROM oceanbase.gv$sql_audit t1, __all_server t2  
WHERE t1.svr_ip = t2.svr_ip 
AND tenant_id = 1001
AND SQL_ID = 'BF7AA13A28DF50BA5C33FF19F1DBD8A9'
AND IS_EXECUTOR_RPC = 0    
AND request_time > (time_to_usec(now()) - 1000000)    
AND request_time < time_to_usec(now())
GROUP BY t1.svr_ip;
```
