Help: How to find MySQL query log?


Ozz

Recommended Posts

I have huge load on my site because of mysql database queries.

I did necessary indexes and make some optimisations on data values. Now I'm tryin "EXPLAIN SELECT" query to find slow queries.

But if I get a query log with query times that will be a shortcut to find the problem.

Has mysql got a query log and where can I find it?

Do you recommend a tool or script to log mysql queries?

If I can see on the server that would be so helpful. But I can try on my windows localhost too.

You can definitely turn on general query logging; however, I recommend using the [a href=\"http://dev.mysql.com/doc/refman/4.1/en/slow-query-log.html\" target=\"_blank\"]slow query log[/a] instead -- it narrows down the log quite a bit, and makes it much easier to find the offending queries.
