      I have the following error in my log file

       

      ErrMsg:’performance_schema.stmt_history_long.SQL_TEXT’ isn’t in GROUP BY

      [6.2] [2014-11-17 16:46:52] [Server: Test Cluster] sniffer.cpp(321) ErrCode:-1 ErrMsg:ExecuteAndStoreResult: Query execution failed

      [6.2] [2014-11-17 16:47:52] [Server: Test Cluster] src/ymysql.cpp(696) ErrCode:2006 ErrMsg:MySQL server has gone away

      [6.2] [2014-11-17 16:47:52] [Server: Test Cluster] src/ymysql.cpp(696) ErrCode:1055 

       

      I think this might be due to my SQL_MODE  ( only full_group_by ) 

       

      root@localhost[information_schema]> show variables like ‘sql_mode’;

      Hi,

       

      The issue is reproducible with sql_mode=’ONLY_FULL_GROUP_BY’ and we would fix this in the upcoming release.

       

      The real-time in MONyog uses the SHOW FULL PROCESSLIST query and not the performance_schema database of the MySQL server and the issue is related to performance schema based sniffer and not real-time. If this is an urgent issue please feel free to write back to us at support@webyog.com

       

       

      Regards,

      Siddhant Tyagi

      Team MONyog
