Performance Schema configuration can be modified dynamically by updating tables in the performance_schema database through SQL statements. Some of the setup tables have columns that can be modified to affect Performance Schema operation; some also permit rows to be inserted or deleted. In my An Overview of the MySQL Performance Schema article, I talked about a relatively new tool called the Performance Schema. WORKBENCH API

Instrumentation is versioned. If the instrumentation implementation changes, previously instrumented code continues to work. This benefits developers of third-party plugins because it is not necessary to upgrade each plugin to stay synchronized with the latest Performance Schema changes.

Check the server error log for information about what went wrong. The Performance Schema is implemented as a storage engine.

For example, use either of these statements to see what Performance Schema tables exist:. The number of Performance Schema tables increases over time as implementation of additional instrumentation proceeds. Queries should specify the names in lowercase. The following examples illustrate a few uses for these tables. For detailed information about the tables in each group, see Section Initially, not all instruments and consumers are enabled, so the performance schema does not collect all events.

To turn all of these on and enable event timing, execute two statements the row counts may differ depending on MySQL version :. It contains one row per thread showing each thread's most recent monitored event:. The first few columns provide the following information:. The ID columns indicate which thread the event comes from and the event number. The timer columns show when the event started and stopped and how long it took.

Timer values are approximate and expressed in picoseconds. For information about timers and event time collection, see Section For example, to see information for recent events produced by thread 13, do this:. As new events are added to a history table, older events are discarded if the table is full.

Summary tables provide aggregated information for all events over time. The tables in this group summarize event data in different ways. In production builds it is not hot because it is nonexistent. Instance tables document what types of objects are instrumented. An instrumented object, when used by the server, produces an event. These tables provide event names and explanatory notes or status information.

Setup tables are used to configure and display monitoring characteristics. To understand how to interpret instrument names, see Section For example:. For more information about the setup tables and how to use them to control event collection, see Section There are some miscellaneous tables that do not fall into any of the previous groups.

For information about timers, see Section Performance Schema Quick Start. Performance Schema Build Configuration. Performance Schema Startup Configuration. Performance Schema Runtime Configuration. Performance Schema Event Timing. Performance Schema Event Filtering. Event Pre-Filtering.
