The DPM user will need permission to update the performance_schema.setup_consumers table: More information about configuration files, including correct JSON formatting, is available here. This is the sysbench command used: Capture the data using slow log + long_query_time = 0, Capture data using pt-query-digest –processlist. Unlike traditional monitoring products that observe aggregate metrics about server status, VividCortex measures query performance in 1-second detail at any scale. It’s recommended to disable this feature (except for Aurora). 4. As a performance and benchmarking expert myself, I have my own interpretation of the results, which are more nuanced. This column is set to NULL when the event starts and updated to the thread current event number when the event ends, but when testing, there were too many missing queries.

Most of the P_S tables follow a set of predictable conventions: there’s a set of tables with a limited set of full-granularity current and/or historical data, which is aggregated into tables that accumulate over time. SolarWinds, VividCortex - database performance monitoring which provides insights into query behavior and resource utilization so you can improve app efficiency and up-time. I am currently monitoring about 150 MySQL servers grouped into about 20 different clusters of masters/slaves/xtradb-clusters. * You can write alerting rules against the timeseries. #    5 0x84D1DEE77FA8D4C3  4.6906  7.9%  7350 0.0006  0.00 SELECT sbtest? #    6 0x3821AE1F716D5205 28.1566  8.8%  2013 0.0140  0.17 SELECT sbtest?

Performance Schema events are distinct from events written to the server's binary log (which describe data modifications) and Event Scheduler events (which are a type of stored program). statements inside stored procedures. Second option: The events_statements_history table contains the most recent statement events per thread and since statement events are not added to the events_statements_history table until they have ended, using this table will do the trick without additional conditions in order to know if the event is still running or not. MySQL 5.6 might not be more widely used, as was already pointed out in this same blog. Database Performance Analyzer vs VividCortex; Database Performance Analyzer vs VividCortex.
