Employee +2 Vote Up -0Vote Down

I recognized many of these from the first seminar but there were some new faces as well.

This time, Mark Leith came on a visit from the UK. He gave an introduction to Performance Schema and ps_helper. ps_helper is a really nice tool to …

Disabling MySQL Enterprise Monitor Graph
+0 Vote Up -0Vote Down

We have setup our database servers to log all slow queries > 2 seconds. This can be done by enabling below from your configuration file or via runtime using SET GLOBAL command.

Append to configuration (my.cnf) under [mysqld]

slow_query_log = on
long_query_time = 2

Using query

SET GLOBAL slow_query_log = on;
SET GLOBAL long_query_time = 2

With this current setup, we filtered all queries from our application running more than 2 seconds. This is a good way to identify slow queries and optimise them.

Employee +7 Vote Up -2Vote Down

I’ve always had a passion for helping people, which is why I think I did “OK” in Support. However I’ve always also had a second passion which has been bubbling away for me too - building solutions for diagnosing database issues. I started in the database world in the Oracle market, working on monitoring and management tools. MySQL “poached” …

"How to find the source of queries in MySQL Query Analyzer" or "SQL comments in Query Analyzer"
Employee +0 Vote Up -0Vote Down


MySQL Enterprise Monitor offers a tool called "Query Analyzer" (QuAn). QuAn sits between any client app and the MySQL server and logs every query and its runtime statistics. A very cool tool for analyzing your SQL. More information is available here.If you identify a query, that needs some improvement, sometimes it is hard to identify the source of that query as well. With hundreds of different PHP scripts for example it is not easy to know, …
