C-Level MySQL

The old adage that time is money does not give any hints about buying more time. A MySQL Enterprise subscription does allow you to purchase time. Your technical staff has to do more with less time than ever before and operational delays add up extremely quickly.  Having the right tools when things go critical means staff can do what they need to do, when they need to do it.

 

So how does MySQL Enterprise Edition buy you more time?

 

When things inevitably go wrong, searching for free answers to problems on web sites with many dubious or flat out wrong solutions is a waste of precious time.  Informational websites like are fine sources of general information for researching technical issues but not when mission critical services are degraded or down.  An online recommendation to do what very large Enterprise Company does may not make sense for your company if you are not …

MySQL 8: Performance Schema Digests Improvements

Tweet

Since MySQL 5.6, the digest feature of the MySQL Performance Schema has provided a convenient and effective way to obtain statistics of queries based on their normalized form. The feature works so well that it has almost completely (from my experience) replaced the connector extensions and proxy for collecting query statistics for the Query Analyzer (Quan) in MySQL Enterprise Monitor (MEM).

MySQL 8 adds further improvements to the digest feature in the Performance Schema including a sample query with statistics for each digest, percentile information, and a histogram summary. This blog will explore these new features.

What Does I/O Latencies and Bytes Mean in the Performance and sys Schemas?

Tweet

The Performance Schema and sys schema are great for investigating what is going on in MySQL including investigating performance issues. In my work in MySQL Support, I have a several times heard questions whether a peak in the InnoDB Data File I/O – Latency graph in MySQL Enterprise Monitor (MEM) or some values from the corresponding tables and view in the Performance Schema and sys schema are cause for concern. This blog will discuss what these observations means and how to use them.

The Tables and Views Involved

Enterprise Monitor: “Add Bulk MySQL Instances” 50 in 1-click.

Carrying on with my MySQL 5.7 Labs Multi Source Replication scenario, I wanted to evaluate performance impact via MySQL Enterprise Monitor.

Whilst I opened my environment, I remember that I had generated lots of different skeleton scripts that allowed me to deploy the 50 servers quickly, and I didn’t want to add each of my targets 1 by 1 in MEM. So, I used one of the many features available, “Add Bulk MySQL Instances”.

So, I’ve got 50 (3001-3050) masters but only 1 slave (3100).

By default, MEM monitors it’s own repository, i.e. the 1/1 server being monitored in the All group.

I want to add my slave in first, because that’s how I’m organizing things, and I’ll take the opportunity to create the monitoring group I want to …

MySQL Enterprise Monitor – send advisor events to your chat client with Perl and Jabber

MySQL Enterprise Monitor (MEM) is part of the MySQL Enterprise Edition, and MEM provides real-time visibility into the performance and availability of all your MySQL databases. MEM and the MySQL Query Analyzer continuously monitor your databases and alerts you to potential problems before they impact your system. It’s like having a “Virtual DBA Assistant” at your side to recommend best practices to eliminate security vulnerabilities, improve replication, optimize performance and more. As a result, the productivity of your developers, DBAs and System Administrators is improved significantly.

With MEM, you have a couple of notification options for receiving information when MEM has received an event alert. An event alert is a “significant deviation from the baseline performance …

MEM 3.0: Getting started

Time to install MEM 3.0, and get its built-in agent working.

[ If you want some tips on What's New, have a look here. ]

I’ve downloaded the Monitor Server and the agent zipped s/w for Linux & Win from http://edelivery.oracle.com:

mysqlmonitor-3.0.0.2887-linux-x86-installer.bin
mysqlmonitoragent-3.0.0.2887-linux-glibc2.3-x86-32bit-installer.bin
mysqlmonitoragent-3.0.0.2887-windows-installer.exe

The Monitor install

So, on my Oracle Linux machine:

./mysqlmonitor-3.0.0.2887-linux-x86-installer.bin

It all installs fine. No issues, if you’re used to MEM 2.3.

Double check your configuration_report.txt :

MySQL Enterprise Monitor (Version 3.0.0.2887 : 3.0.0.2887)

Here are the settings you …

MySQL Connect HOL content posted

Just a quick post to note that the content from my hands-on lab at MySQL Connect (“MySQL Enterprise Features in Practice”) has been uploaded to the content catalog, and can be found here.  This includes the 36-page lab manual and example commands and programs (mostly in Java; the package includes both compiled and source code).  For those who attended the lab, this is an opportunity to complete the exercises we didn’t get to in the 2.5 hours, and for those who missed it, an opportunity to learn more about the features and capabilities of key MySQL Enterprise products and features such as MySQL Enterprise Audit plugin, MySQL Enterprise Monitor and MySQL Enterprise Security (PAM plugin).  I hope to expand on the lab content …
