29.14 Performance Schema Command Options (original) (raw)

Performance Schema parameters can be specified at server startup on the command line or in option files to configure Performance Schema instruments and consumers. Runtime configuration is also possible in many cases (seeSection 29.4, “Performance Schema Runtime Configuration”), but startup configuration must be used when runtime configuration is too late to affect instruments that have already been initialized during the startup process.

Performance Schema consumers and instruments can be configured at startup using the following syntax. For additional details, seeSection 29.3, “Performance Schema Startup Configuration”.

• --performance-schema-consumer-_consumer_name_=value
  Configure a Performance Schema consumer. Consumer names in thesetup_consumers table use underscores, but for consumers set at startup, dashes and underscores within the name are equivalent. Options for configuring individual consumers are detailed later in this section.
• --performance-schema-instrument=_instrument_name_=value
