Hi, Sergei I'm developing a mariadb monitoring plugin type agent. We're planning to contribute our monitoring solution for mariadb in one or two months. Our solution is consist of plugin type agent, APM Server and Dashboard. Our plugin type agent collect data by using low level interface instead of using query. I can collect a information_schema.global_status and performance_schema.event_xxxx_table for your help in the past. By referencing the source of feedback.cc, I can collect data from global_status using fill_stauts function. I hava a question. I need to collect data from information_schema.innodb_locks for lock monitoring. But I found that I must use trx_i_s_common_fill_table in i_s.cc for reading of innodb_locks table and that fuction is static. so I only access that function by function pointer. Debugging source for many days, I guess that I must use ST_SCHEMA TABLE's fill_table member variable for pointing to trx_i_s_common_fille_table function. Right? But I don't know how to that. I attemped in various ways for many days. but I failed. If possible. please let me know how to read data of information_schema.innodb_locks using native api. Thanks in advance.
