Has MySQL a built-in way to easily take a look at the overall server status without the need to execute many different custom query or program ? Maybe something similar to an oracle AWR report ?

Starting with MySQL 5.7.9 and later we can use the SYS procedure “diagnostics()” for that which rely the information available on the PERFORMANCE_SCHEMA !

Let’s give it a try  by generating a HTML report for the currently running instance (starts an iteration every 30 seconds and runs for at most 60 seconds using the current Performance Schema settings ) :

mysql -u root -p -H -e"CALL sys.diagnostics(60, 30, 'current');" > ./current_instance_report.html

The report contain information such as :

ProxySQL is an intelligent and high-performance SQL proxy which supports MySQL, MariaDB and ClickHouse. Recently, ProxySQL 2.0 has become GA and it comes with new exciting features such as GTID consistent reads, frontend SSL, Galera and MySQL Group Replication native support.

It is relatively easy to run ProxySQL as Docker container. We have previously written about how to run ProxySQL on Kubernetes as a helper container or as a Kubernetes service, which is based on ProxySQL 1.x. In this blog post, we are going to use the new version ProxySQL 2.x which uses a different approach for Galera Cluster configuration. …

In this blog post, I’m going to show you how to test Kubernetes locally on OSX/macOS. Testing Kubernetes without having access to a cloud operator in a local lab is not as easy as it sounds. I’d like to share some of my experiences in this adventure. For those who have already experienced in Virtualbox & Vagrant combination, I can tell you that it doesn’t work. Since Kubernetes will require virtualization, setting another virtual environment within another VirtualBox has several issues. After trying to bring up a cluster for a day or two, I gave up my traditional lab and figured out that Kubernetes has an alternate solution called minikube.

Installation

If your OSX/macOS doesn’t have brew I strongly recommend installing …

MySQL Enterprise Data Masking and De-Identification hides sensitive information by replacing real values with substitutes in order to protect sensitive data while they are still look real and consistent.

In this post we describe MySQL connections, user threads, and scaling. We hope that an increased understanding of how MySQL works will help application developers and system administrators to make good choices and trade-offs. We describe how connections work in a plain community server and we do not cover related topics such as thread pooling, resource groups, or connection multiplexing in this post.…
