Sun Microsystems is offering MySQL customers a free tool to enhance
and monitor database query performance as part of its MySQL Enterprise
subscription service.
Sun’s new MySQL Query Analyzer is a new addition to MySQL's lineup.
Integrated into the MySQL Enterprise Monitor application, the query
analyzer is meant to help designers and database administrators find
any problematic SQL code hurting performance.
To accomplish this, the tool leverages MySQL’s proxy technology to
extend the Service Agent to listen on a user-defined port for
application queries. It then collects the SQL code and performance
metrics and reports the results back to the Service Manager. Doing all
this without the tool would require visiting each MySQL server,
pulling out the data and analyzing it in a much more manual
process.
“This takes a lot of time,” said Robert Young, senior product
manager for MySQL Enterprise. “With our new tool, we can allow people
to do that very same operation in about two minutes as opposed to two
days or two weeks.”
The product offers a consolidated view into query execution counts
and runtime across all MySQL servers with no dependence on MySQL logs
or show processlist. Queries can be searched and sorted in a number of
ways, including by content, server, type or data and time.
The worst performing queries are presented will full drill down
details, including execution time and the originating session, thread
and user ID, so the user can identify what variable combinations are
leading to performance problems.
"The new MySQL Query Analyzer gives us a better level of visibility
into our database performance that we have never had before," said Phil
Hildebrand, senior DBA at thePlatform, a subsidiary of Comcast
Interactive Media, in a statement. "Not only does it save us both time
and resources, it allows us to be far better prepared when these
applications go live, understanding exactly the demands that will be
placed on the system."
The new version of the MySQL Enterprise subscription service will be
commercially available within 30 days. Thirty-day trial subscriptions
for the service are now available free-of-charge.
