At work we have been looking for tools to monitor MySQL and at the same time provide as much diagnosis information as possible upfront when an alarm is triggered. After looking around at different options, I decided to test MONyog from Webyog, the makers of the better known SQLyog. Before we go on, the customary disclaimer: This review reflects my own opinion and in no way represents any decision that my current employer may or may not make in regards of this product.

First Impression

You know what they say about the first impression, and in this where MONyog started with the right foot. Since it is an agent-less system, it only requires to install the RPM or untar the tarball in the server where you're going to run the monitor and launch the daemon to get started. How much faster or simpler can it be? But

My proposal has been accepted, yay!

I'll be speaking on a topic that I feel passionate about: MySQL Server Diagnostics Beyond Monitoring. MySQL has limitations when it comes to monitoring and diagnosing as it has been widely documented in several blogs.

My goal is to share my experience from the last few years and, hopefully, learn from what others have done. If you have a pressing issue, feel free to comment on this blog and I'll do my best to include the case in my talk and/or post a reply if the time allows.

I will also be discussing my future plans on sarsql. I've been silent about this utility mostly because I've been implementing it actively at work. I'll post a road map shortly based on my latest experience.

I'm excited about meeting many old friends (and most now fellow MySQL alumni) and making new ones. I hope to see you there!

Last week I blogged about the upcoming MySQL Users conference, in particular about the Writing MySQL UDFs tutorial that I will be delivering.

I will also be doing the Grand Tour of the Information Schema and its Applications.


I will discuss the elements in the

The MySQL User's conference will be held in less than a month from now!!!

This year there is quite a good number of sessions on adding your own functions and procedures, such as:

• Advanced Stored Procedures


• A Tour of External Language Stored Procedures for MySQL


• Code Generators for MySQL Plugins and User Defined Functions (UDFs)


• Extending

Let's see if you can solve this little puzzle...

Consider this stored procedure:

-- finds the first slash and exits
create procedure p_find_slash(p_text text)
begin
    declare v_index int default 1;
    declare v_length int default character_length(p_text);
    declare v_char char(1);
    
    _main_loop: while v_index -- loop over all characters
                
        set v_char := substring(p_text, v_index, 1);               -- grab the current character
        case v_char
            when v_char = '/' then                                 -- found a slash!                
                select concat('A slash at ', v_index) message;     -- report it
                leave _main_loop;                                  -- and then stop
