In my last blog post we have seen how we can easily collect general MySQL status information using the sys.diagnostics() procedure. What about a single session/thread ? Is there built-in way to easily trace a target thread/session activity (ex: transactions/ statements/stage/wait events) like using an oracle SQL trace ?

The procedure “ps_trace_thread()” introduced in MySQL 5.7 allow monitoring a specific thread. This procedure is based on Mark Leith work in his blog post A Big Bag of Epic Awesomeness. (I love the title :))

It will  captures as much information on the thread activity as possible depending on the actual …

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 :

Wait event :

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 …
