SHOW PROFILES 

The SHOW PROFILES  statement, together with SHOW PROFILE , displays profiling information that indicates resource usage for statements executed during the course of the current session. For more information, see Section 13.7.7.30, “SHOW PROFILE Statement” . 

## 13.7.7.32 SHOW RELAYLOG EVENTS Statement 

<img src='content_image/813716.jpg'>

SHOW RELAYLOG EVENTS 

[IN ’ log_name ’] [FROM pos ] [LIMIT [ offset ,] row_count ] [ channel_option ] 

channel_option : 

FOR CHANNEL channel 

Note 

The SHOW PROFILE  and SHOW PROFILES  statements are deprecated; expect it to be removed in a future MySQL release. Use the Performance Schema instead; see Section 27.19.1, “Query Profiling Using Performance Schema” . 

Shows the events in the relay log of a replica. If you do not specify ’ log_name ’ , the first relay log is displayed. This statement has no effect on the source. SHOW RELAYLOG EVENTS  requires the REPLICATION SLAVE  privilege. 

The LIMIT  clause has the same syntax as for the SELECT  statement. See Section 13.2.10, “SELECT Statement” .

Note 

Issuing a SHOW RELAYLOG EVENTS  with no LIMIT  clause could start a very time- and resource-consuming process because the server returns to the client the complete contents of the relay log (including all statements modifying data that have been received by the replica). 

The optional FOR CHANNEL channel  clause enables you to name which replication channel the statement applies to. Providing a FOR CHANNEL channel  clause applies the statement to a specific replication channel. If no channel is named and no extra channels exist, the statement applies to the default channel. 

When using multiple replication channels, if a SHOW RELAYLOG EVENTS  statement does not have a channel defined using a FOR CHANNEL channel  clause an error is generated. See Section 17.2.2, “Replication Channels”  for more information. 

SHOW RELAYLOG EVENTS  displays the following fields for each event in the relay log: 

• Log_name 

The name of the file that is being listed. 

• Pos 

The position at which the event occurs. 

• Event_type 

An identifier that describes the event type.
