Easy query metrics with MySQL Performance Schema

The MySQL Performance Schema exposes so much data that it’s not trivial to learn, configure, and use. With recently released Percona Agent 1.0.11 you can get query metrics – like min, max, and average query execution time – with a few clicks:

Click “Apply” and about two minutes later you’ll have query metrics from Performance Schema, collected and sent every minute.

Percona Cloud Tools (PCT) and Percona Agent handle all the details. You’ll need MySQL (or Percona Server) 5.6 and Percona Agent 1.0.11 or newer. One caveat at the moment: it …

Faster fingerprints and Go packages for MySQL

I’m happy to announce Go packages for MySQL. Particularly exciting is a new query fingerprint function which is very fast and efficient, but I’ll talk about that later. First, go-mysql is currently three simple Go packages for parsing and aggregating MySQL slow logs. If you’ve been following Percona development, you’ve no doubt heard of Percona Cloud Tools (PCT), a somewhat new performance management web service for MySQL.

One tool in PCT is “Query Analytics” which continuously analyzes query metrics from the slow log. The slow log provides the most metrics and therefore the most performance insight into MySQL. percona-agent, the open-source agent for PCT, uses …

5 great new features from Percona Cloud Tools for MySQL

It’s been three months since we announced anything for Percona Cloud Tools, not because we’ve been idle but because we’ve been so busy the time flew by!  Here’s the TL;DR to pique your interest:

  • EXPLAIN queries in real-time through the web app
  • Query Analytics for Performance Schema
  • Dashboards: customizable, shared groups of charts
  • Install and upgrade the agent with 1 command line
  • Unified UI: same time range, same host wherever you go

Percona Cloud Tools for MySQL is a hosted service providing access to query performance insights for all MySQL uses. After a brief setup, unlock new information about your database and how to improve your applications. There’s a lot more, but let’s just look at these five new features…

Why did we develop percona-agent in Go?

We recently open-sourced our percona-agent and if you check out the source code, you’ll find that it is written in the Go programming language (aka Golang). For those not up to speed, the percona-agent is a real-time client-side agent for Percona Cloud Tools.

Our requirements are quite demanding for our agents. This one is software that works on a real production server, so it must be fast, reliable, lightweight and easy to distribute. Surprisingly enough, binaries compiled by Go fit these characteristics.

There are of course alternatives that we considered. On the scripting side: Perl, Python, PHP, Ruby et al. These are not necessarily fast, and the distribution is also interesting. We have enough experience with …

Introducing the 3-Minute MySQL Monitor

There are many cool, new things happening with Percona Cloud Tools.  To avoid “tl;dr” I will highlight only one new feature after a brief, general announcement.  The new feature is a 3-minute MySQL monitor.  I’ll blog later about other features.

The general announcement is: Last week we quietly released a brand-new agent called percona-agent, and we added MySQL and system monitoring to Percona Cloud Tools.  We also wrote a brand-new API from the ground up.  We call it all “PCT v2″.  For you it means a better experience and more features, all still free while we’re in beta.

One new feature in Percona Cloud Tools v2 is MySQL monitoring in 3 minutes, i.e. a 3-minute MySQL monitor.  Let’s be honest about monitoring: We …
