Something cool that is in version 5.0.37 of the community server is <a href="http://web.archive.org/web/20110609054749/http://dev.mysql.com/tech-resources/articles/using-new-query-profiler.html" rel="noreferrer">MySQL's new profiler</a>. 

This may give you what info you are looking for.

Are you wanting to monitor performance, or just see which queries are executing? If the latter, you can configure MySQL to log all queries it's given. On a RedHat Linux box, you might add

<code>log = /var/lib/mysql/query.log</code>

to the [mysqld] section of <code>/etc/my.cnf</code> before restarting MySQL.

Remember that in a busy database scenario, those logs can grow quite large.

In my opinion I've found everything here in raw....

Find and open your MySQL configuration file, usually /etc/mysql/my.cnf on Ubuntu. Look for the section that says “Logging and Replication”

<pre><code># * Logging and Replication
# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.

log = /var/log/mysql/mysql.log
</code></pre>

or in newer versions of mysql, comment OUT this lines of codes

<pre><code>general_log_file = /var/log/mysql/mysql.log
general_log = 1
log_error = /var/log/mysql/error.log
</code></pre>

Just uncomment the “log” variable to turn on logging. Restart MySQL with this command:
 sudo /etc/init.d/mysql restart

Now we’re ready to start monitoring the queries as they come in. Open up a new terminal and run this command to scroll the log file, adjusting the path if necessary.

<pre><code>tail -f /var/log/mysql/mysql.log
</code></pre>

blocks|key|1565330|text|如果是付费版本，Jet+Profiler就很好。LogMonitor只是将其指向mysql日志文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565331|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Jet Profiler is good if it's a paid version. The LogMonitor just point it to the mysql log file.

blocks|key|1565544|text|不确定图形用户界面，但有一个命令帮助我使用工作台在MySQL中分析了很多存储过程：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565545|SET+profiling+=+1;

Not sure about graphical user interface but there is a command that has helped me profile stored procedures a lot in MySQL using workbench:

<pre><code>SET profiling = 1;
call your_procedure;
SHOW PROFILES;
SET profiling = 0;
</code></pre>

blocks|key|1780272|text|如果5.0.37版不可用，您可能需要查看mytop。它只是输出服务器的当前状态，但允许您按照mercutio提到的方式对特定查询运行EXPLAIN。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1780273|entityMap|0|LINK|mutability|MUTABLE|url|http://jeremy.zawodny.com/mysql/mytop/^0|K|5|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

If version 5.0.37 isn't available, you might want to look at <a href="http://jeremy.zawodny.com/mysql/mytop/" rel="nofollow noreferrer">mytop</a>. It simply outputs the current status of the server, but allows you to run EXPLAIN as (mentioned by mercutio) on particular queries.

blocks|key|1565100|text|我不知道是否有类似的分析应用程序，但使用EXPLAIN语法来分析查询是很常见的。您可以使用它们来找出要创建的最佳索引，或者您可以尝试更改整个查询，看看它如何改变效率，等等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565101|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I don't know about any profiling apps as such, but it's commonplace to use the EXPLAIN syntax for analysing queries. You can use these to figure out the best indexes to create, or you can try changing the overall query and see how it changes the efficiency, etc.

"Microsoft SQL Server Profiler is a graphical user interface to SQL Trace for monitoring an instance of the Database Engine or Analysis Services."

I find using SQL Server Profiler extremely useful during development, testing and when I am debugging database application problems. Does anybody know if there is an equivalent program for MySql?

Is there a Profiler equivalent for MySql?
