What is great with MySQL Shell Plugins, it’s that it provides you an infinite amount of possibilities. While I was writing the part I and part II of the check plugin, I realized I could extend it event more.

The new methods I added to the plugin are especially useful when you are considering to use MySQL InnoDB Cluster in Multi-Primary mode, but not only

Let’s have a look at these new methods:

These 4 new methods are targeting large queries or large transactions. It’s also possible to get the eventual hot spots.

Let’s see the first two that are more basic in action:

The first method …

Introduction MySQL offers two types of clustering solution for managing Read/Write intensive workloads , ensuring Rock Solid Availability.

1.MySQL InnoDB Cluster
2. MySQL NDB Cluster

Glimpse of MySQL InnoDB Cluster    This Cluster is designed for users that uses MySQL Server with InnoDB storage engine.    It will serve as a natural extension for users currently using MySQL Replication with InnoDB to a       new replication architecture i.e Clustering on top of Group Replication. MySQL InnoDB Cluster = MySQL Server + MySQL Shell + MySQL Router.
MySQL Server

• Group Replication Technology.
• Single-Primary /Multi-Primary Mode.
• Fault Tolerance.
• Conflict detection and resolution.
• Automatic distributed recovery.

MySQL Shell

• Multi-Language(Python , Java script , …

If you do a quick web search about UUIDs and MySQL, you’ll get a fair number of results. Here are just a few examples:

• Storing UUID and Generated Columns
• Storing UUID Values in MySQL
• Illustrating Primary Key models in InnoDB and their impact on disk usage
• MySQL UUID Smackdown: UUID vs. INT for Primary Key

In a couple previous posts, I explained how to get an “Always Free” Oracle Cloud compute instance and how to install MySQL on it – as well as how to add a web server.

I started my IT career (way back in 1989) using a (dumb) terminal and a 2400-baud modem to access a server. While I still use a terminal window and the command-line, it is always nice to have access to a GUI. In this post, I will show you how to install and use a GUI on your Oracle Cloud …

As Grafana powers our star product – Percona Monitoring and Management (PMM) – we have developed a lot of experience creating Grafana Dashboards over the last few years.   In this article, I will share some of the considerations for designing Grafana Dashboards. As usual, when it comes to questions of design they are quite subjective, and I do not expect you to chose to apply all of them to your dashboards, but I hope they will help you to think through your dashboard design better.

Design Practical Dashboards

Grafana features many panel types, and even more are available as plugins. It may be very attractive to use many of them in your dashboards using many different visualization options. Do not!  Stick to a few data visualization patterns and only add additional visualizations when they provide …

In the first part of this article related to the check plugin, we discovered information retrieved from the binary logs. This part, is about what Performance_Schema and SYS can provide us about the queries hitting the MySQL database.

Currently, 3 methods are available:

• getSlowerQuery()
• getQueryTempDisk()
• getFullTableScanQuery()

The method’s name should be self explaining.

This is an overview of the parameters for each methods:

ext.check.getSlowQuery()ext.check.getQueryTempDisk()ext.check.getFullTableScanQuery()

Some methods allow a select parameter if only SELECT statements should be returned.

When only one query is returned (default), it’s also possible to …

In the first part of this blog, we covered a deployment walkthrough of MySQL InnoDB Cluster with an example on how the applications can connect to the cluster via a dedicated read/write port.

In this operation walkthrough, we are going to show examples on how to monitor, manage and scale the InnoDB Cluster as part of the ongoing cluster maintenance operations. We’ll use the same cluster what we deployed in the first part of the blog. The following diagram shows our architecture:

We have a three-node …
