27.4.5.10 The ps_is_consumer_enabled() Function

Contents

Returns YES or NO to indicate whether a given Performance Schema consumer is enabled, or NULL if the argument is NULL. If the argument is not a valid consumer name, an error occurs. (Prior to MySQL 8.0.18, the function returns NULL if the argument is not a valid consumer name.)

This function accounts for the consumer hierarchy, so a consumer is not considered enabled unless all consumers on which depends are also enabled. For information about the consumer hierarchy, see Section 26.4.7, “Pre-Filtering by Consumer”.

Parameters

  • in_consumer VARCHAR(64): The name of the consumer to check.
