Question

Im recording slow queries longer than 2 seconds. That is running fine except, the daily backups also get recorded in slow log because 1) mysqldump calls select * from xyz (big table); and 2) when inserting the backup into a new db (yesterday’s backup, sundays backup, etc).
How to prevent mysqldump from logging slow queries?
Is there a temporary way to switch off slow logging when backup is in progress?
Please suggest.

Thanks,
Vikas

I think that answers it:

To control the slow log at runtime,
use the global slow_query_log and
slow_query_log_file system variables.
Set slow_query_log to 0 (or OFF) to
disable the log or to 1 (or ON) to
enable it. Set slow_query_log_file to
specify the name of the log file. If a
log file already is open, it is closed
and the new file is opened.
