This document summarizes MySQL's monitoring mechanisms and how they have evolved over time. It discusses tools like SHOW statements, INFORMATION_SCHEMA, slow/general query logs, and EXPLAIN that provided limited visibility in past versions. MySQL 5.5 introduced the Performance Schema framework for detailed instrumentation. Subsequent versions have expanded instrumentation to provide more developer-focused statistics on statements, stages, I/O, locks and more. New INFORMATION_SCHEMA tables in 5.6 provide additional InnoDB statistics on data dictionary, buffer pool, transactions and compression. The optimizer trace exposes query transformations. Enhanced EXPLAIN now supports more statement types and future improvements will provide a structured EXPLAIN output.
Performance Schema and Sys Schema in MySQL 5.7Mark Leith
MySQL 5.7 now includes the Sys Schema by default, which builds upon the awesome instrumentation framework laid by Performance Schema.
Performance Schema has had 23 worklogs completed in 5.7 alone, such as memory instrumentation, tying in transactions and stored programs in to the current statement/stage/wait instruments and wait graph, prepared statement instruments, metadata lock information, improved session status and variable reporting, the new structured replication tables, and more.
The Sys schema builds upon this strong foundation with easy reporting views and functions, as well as procedures to help both set up and manage the configuration of Performance Schema, and help diagnose performance issues with your database instances on the whole.
Come along and hear from the original developer of the Sys schema about all of these exciting improvements in MySQL instrumentation for the upcoming MySQL 5.7 release!

The 5.5 and 5.6 releases of MySQL introduce several new mechanisms that provide improved monitoring and performance tuning functionality. Examples are performance schemas, InnoDB metrics tables, optimizer trace, and extended explain functionality. This session outlines the vision for monitoring-related functionality in MySQL and presents an overview of the new mechanisms. It shows how these are integrated with MySQL management tools. Furthermore, it discusses how these mechanisms can be utilized by application developers, DBAs, and production engineers for tracking down performance issues and monitoring production systems.

The MySQL sys schema was integrated fully into MySQL Server from version 5.7.7 and has been improved in MySQL 8.0. Whether you are a DBA trying to determine where the resources are being used on your database instance and by whom, or a developer trying to figure out why your MySQL statements are running too slowly, the MySQL sys schema can help. Join this session to learn how to better use the MySQL sys schema to answer your day-to-day questions—from the original developer of the MySQL sys schema.

Performance Schema for MySQL TroubleshootingSveta Smirnova
Percona Live (https://www.percona.com/live/data-performance-conference-2016/sessions/performance-schema-mysql-troubleshooting)
The performance schema in MySQL version 5.6, released in February, 2013, is a very powerful tool that can help DBAs discover why even the trickiest performance issues occur. Version 5.7 introduces even more instruments and tables. And while all these give you great power, you can get stuck choosing which instrument to use.
In this session, I will start with a description of a typical problem, then guide you how to use the performance schema to find out what causes the issue, the reason for unwanted behavior and how the received information can help you solve a particular problem.
Traditionally, performance schema sessions teach what is in contained in tables. I will, in contrast, start from a performance issue, then demonstrate which instruments and tables can help solve it. We will discuss how to setup the performance schema so that it has minimal impact on your server.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
