Over the last couple years on the VividCortex blog, we've discussed a huge range of database monitoring concepts. We've examined ideas we're excited about, shared monitoring practices we recommend, and explored some of the principles that shape our own projects and goals. Of these many posts, however, there are a few in particular worth emphasizing and discussing again and again. Generally, these posts explore the math and statistics behind key monitoring practices and they champion why smart database monitoring is so important; they're often our most read articles, the most indicative of what we value, the influences that make VividCortex a unique product.  

The list below is a quick review of some of VividCortex's key blog posts, coming together to make a Greatest Hits list of our recommended best practices and fundamental concepts.

The relational database world just changed and you didn't notice, did you? Rather than speaking SQL to your data, what if you could talk to it in PHP directly? No longer do you have to struggle to remember arcane structured query language syntax and just grab data with PHP. You can still write bad queries full of N+1 errors and a whole host of other problems. But you are speaking PHP to your data. And this started with MySQL 5.7.12 and its new Document Store Functionality.

The Document Store functionality expands on the new JSON data type in MySQL 5.7 with a new server plugin, a new API, and a suite of new components designed to make MySQL accessible for users who are not familiar with the SQL language or prefer to use a schemaless data store. This MySQL Server plugin enables communication using the X Protocol. And clients that implement X DevAPI and enables using MySQL as a document store easily. So you can talk to your data in the language …

I thought I posted this long ago... oh well....

We all know that math is the fundamental aspect of all life and the common language used around the world if not beyond. MySQL, like all databases, can help you with numerous aspects of math.

Here is a list of the functions: https://dev.mysql.com/doc/refman/5.6/en/mathematical-functions.html

Here are some simple examples to get you started. 

• The Quadratic Formula  ax^2 + bx + c = 0


# 2x^2  – 4x – 3 = 0.
SET @a=  1;
SET @b=  3;
SET @c= -4;
SET @XX = ( -(@b) - SQRT(  POW(@b,2)  -4 * @a * @c) / POW(@a,2) ) ;
SET @YY = ( -(@b) + SQRT(  POW(@b,2)  -4 * @a * @c) / POW(@a,2) ) ; 
SET @XXX = MOD(@YY, @XX);

This tutorial shows how to install an Ubuntu 16.04 (Xenial Xerus) server (with Apache2, BIND, Dovecot) for the installation of ISPConfig 3.1, and how to install ISPConfig. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers the installation of Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).

Wednesday night at Percona Live 2016 was reserved for fun, fun, fun! Once again, the Percona Live Game Night proved to be a popular and amazing event. There were more games this year than last, as well as food, drinks, and lots of friendly competition!

This year, besides the ever-crowd-pleasing Meltdown Challenge, there were Segway Races, pool, foosball, shuffleboard, Wii Boxing, Pac-Man Attack, a shootout gallery, darts, as well as virtual reality stations and a death-defying trampoline.

You can see Percona’s CEO Peter Zaitsev demonstrating how you use it, pro-level:

We’re heading into the final day here at Percona Live 2016! People are looking a little tired, but still excited for some excellent talks today. Once again the day started off with two great keynote lectures. Read to the end for an important announcement!

Winning with Open Source Databases

Peter discussed what makes the open source community so vibrant and powerful, and why it is essential to preserve that spirit. Data is critical to the success of your business. You rely on your database and its …

RENAME DATABASE statement was removed from MySQL because it was found to be dangerous. However, MySQL still supports the RENAME TABLE command.

There's a new JSON data type available in MySQL 5.7 that I've been playing with. I wanted to share some examples of when it's useful to have JSON data in your MySQL database and how to work with the new data types (not least so I can refer back to them later!)

MySQL isn't the first database to offer JSON storage; the document databases (such as MongoDB, CouchDB) work on a JSON or JSON-ish basis by design, and other platforms including PostgreSQL, Oracle and SQL Server also have varying degress of JSON support. With such wide adoption as MySQL has, the JSON features are now reaching a new tribe of developers.

Why JSON Is Awesome

Traditional database structures have us design table-shaped ways of storing all our data. As long as all your records (or "rows") are the same shape and have the same sorts of data in approximately the same quantities, this works brilliantly well. There are some common problems that aren't a good …
