This is based on the userstatv2 patch from Percona and OurDelta.
The original code comes, as far as I know, from Google (Mark Callaghan's team) with additional work from Percona, Ourdelta and Weldon Whipple. This code provides the same functionallity, but with a lot of changes to make it faster and better fit the MariaDB infrastucture. Added new status variables: - Com_show_client_statistics, Com_show_index_statistics, Com_show_table_statistics, Com_show_user_statistics - Access_denied_errors, Busy_time (clock time), Binlog_bytes_written, Cpu_time, Empty_queries, Rows_sent, Rows_read Added new variable / startup option 'userstat' to control if user statistics should be enabled or not Added my_getcputime(); Returns cpu time used by this thread. New FLUSH commands: - FLUSH SLOW QUERY LOG - FLUSH TABLE_STATISTICS - FLUSH INDEX_STATISTICS - FLUSH USER_STATISTICS - FLUSH CLIENT_STATISTICS New SHOW commands: - SHOW CLIENT_STATISTICS - SHOW USER_STATISTICS - SHOW TABLE_STATISTICS - SHOW INDEX_STATISTICS New Information schemas: - CLIENT_STATISTICS - USER_STATISTICS - INDEX_STATISTICS - TABLE_STATISTICS Added support for all new flush commands to mysqladmin Added handler::ha_... wrappers for all handler read calls to do statistics counting - Changed all code to use new ha_... calls - Count number of read rows, changed rows and rows read trough an index Added counting of number of bytes sent to binary log (status variable Binlog_bytes_written) Added counting of access denied errors (status variable Access_denied_erors) Bugs fixed: - Fixed bug in add_to_status() and add_diff_to_status() where longlong variables where threated as long - CLOCK_GETTIME was not propely working on Linuxm client/mysqladmin.cc: Added support for all new flush commmands and some common combinations: flush-slow-log flush-table-statistics flush-index-statistics flush-user-statistics flush-client-statistics flush-all-status flush-all-statistics configure.in: Added checking if clock_gettime needs the librt.
