     Note

     If your instance uses the cluster or read/write splitting architecture, the following information is displayed: the slow query log details for data nodes and proxy nodes and the number of slow queries of each node.

   • Slow Log Details

     By default, the details of all slow queries are displayed in the following columns: Query Started At, Database Name, Slow Query Statement, Elapsed, and Host Address. You can click Set to filter the columns.

     Note

     • You can click Export Slow Log in the upper-right corner to export slow query logs to local storage for analysis.

     • By default, the Host Address parameter for cluster instances and read/write splitting instances displays the IP addresses of proxy nodes. To obtain the IP address of a specific client, set ptod_enabled to 1 in Parameter Settings. For more information, see Configure instance parameters.
