Event Scheduler Status •Query the  EVENTS  table of the  INFORMATION_SCHEMA  database. See Section 26.3.14, “The INFORMATION_SCHEMA EVENTS Table” . •Use the  SHOW CREATE EVENT  statement. See Section 13.7.7.7, “SHOW CREATE EVENT Statement” . •Use the  SHOW EVENTS  statement. See Section 13.7.7.18, “SHOW EVENTS Statement” . Event Scheduler Time Representation Each session in MySQL has a session time zone (STZ). This is the session  time_zone  value that is initialized from the server’s global  time_zone  value when the session begins but may be changed during the session. The session time zone that is current when a  CREATE EVENT  or  ALTER EVENT  statement executes is used to interpret times specified in the event definition. This becomes the event time zone (ETZ); that is, the time zone that is used for event scheduling and is in effect within the event as it executes. For representation of event information in the data dictionary, the  execute_at ,  starts , and  ends  times are converted to UTC and stored along with the event time zone. This enables event execution to proceed as defined regardless of any subsequent changes to the server time zone or daylight saving time effects. The  last_executed  time is also stored in UTC. Event times can be obtained by selecting from the  INFORMATION_SCHEMA.EVENTS  table or from  SHOW EVENTS , but they are reported as ETZ or STZ values. The following table summarizes representation of event times. Value INFORMATION_SCHEMA.EVENTS SHOW EVENTS Execute at ETZ ETZ Starts ETZ ETZ Ends ETZ ETZ Last executed ETZ n/a Created STZ n/a Last altered STZ n/a 25.4.5 Event Scheduler Status The Event Scheduler writes information about event execution that terminates with an error or warning to the MySQL Server’s error log. See Section 25.4.6, “The Event Scheduler and MySQL Privileges”  for an example. To obtain information about the state of the Event Scheduler for debugging and troubleshooting purposes, run  mysqladmin debug  (see Section 4.5.2, “mysqladmin — A MySQL Server Administration Program” ); after running this command, the server’s error log contains output relating to the Event Scheduler, similar to what is shown here: Events status: LLA = Last Locked At LUA = Last Unlocked At WOC = Waiting On Condition DL = Data Locked 4741 Event scheduler status: State : INITIALIZED Thread id : 0 LLA : n/a:0 LUA : n/a:0
