obproxy_slow.log records logs for slow SQL queries, which refer to queries whose execution time is greater than the threshold (default value: 500 ms) specified by the slow_query_time_threshold parameter.

  • Log format

    Log printing time,Logical tenant name,TraceId,RpcId,Logical database name,Physical database information (cluster:tenant:database),Database type (OB/RDS),Logical table name,Physical table name,SQL command,SQL type (CRUD),Execution result (success/failed),Error code (empty for success),SQL statement,Total execution time (μs),ODP processing time,Connection establishment time,OBServer node execution time,Current thread name,Ignorable fields
    

    where

    • The SQL command can be COM_QUERY or COM_STMT_PREPARE.

    • The total execution time includes the internal SQL execution time.

    • The current thread name indicates the internal thread ID in ODP.

  • Log example

    2022-07-11 14:32:51.758270,undefined,,,,obcluster:sys:test,OB_MYSQL,,,COM_QUERY,SELECT,success,,select sleep(3),3041116us,409us,0us,3039883us,Y0-7F4B1CEA13A0,,,,0,11.xxx.xxx.53:33041
    

obproxy.log also records logs for slow SQL queries with the keyword Slow Query. The logs in obproxy.log provide more details. For example, after you execute the SQL statement select sleep(3) from dual, you can find the following log in obproxy.log:
