The latest from the MySQL community

In this blog post, we’ll show that you can plot MySQL data in real time using Percona Monitoring and Management (PMM).

In my previous blog post, I showed how we could load into any metrics, benchmarks into MySQL and visualize it with PMM. But that’s not all! We can even visualize most any kind of data from MySQL in real time. I am falling in love with the MySQL plugin for Grafana — it just makes things so easy and smooth.

This graph shows us the number of visitors to a website in real …

Have you registered for Percona Live already? The tutorial grid, the schedules for day 1 and day 2 are pretty amazing, and there is even an extra track being added, for a total of 10 concurrent/parallel tracks during day 1 & day 2. If you submitted a talk and it didn’t get accepted (competition was high), you should have received a discount code to register for the event.

In this blog post, I want to go over some of the day-to-day MySQL tools and methods DBAs use to analyze queries and visualize “what is going on?” I won’t be going into the nitty-gritty details of each of these tools, I just want to introduce you to them and show you what they look like so you will know what types of information they provide.

This isn’t a comprehensive list by any means but consider it a primer for those starting with MySQL and wanting to know what a query is going to do or is doing.

The two sides of query analysis are examining a query BEFORE you run it, and then analyzing what actually happened AFTER you run it.

Let’s start with the tools you can use to predict a query’s future.

In the beginning, there was EXPLAIN. The venerable EXPLAIN command has been with us a long time as a built-in MySQL utility statement. Its purpose is to explain that what the optimizer …

In this blog post, we’ll checkout Percona Monitoring and Management vs. gnuplot when it comes to creating great metrics graphs. gnuplot is great, but PMM might provide graphs that are easier to read.

Percona Monitoring and Management (PMM) is our free and open-source platform for managing and monitoring MySQL®, MariaDB® and MongoDB® performance, and is based on Grafana and Prometheus. It collects many kinds of metrics: OS metrics, MySQL metrics or MongoDB metrics. But there are times where you just ran a benchmark or collected your specific metrics and you want to visualize them.

For a long time, I used gnuplot for that (and I still like it). But when I was working on a recent blog post, one of my colleagues wrote me: …

In this blog post, I will look at the new dashboards in Percona Monitoring and Management (PMM) for Prometheus exporters.

Percona Monitoring and Management (PMM) uses Prometheus exporters to capture metrics data from the system it monitors. Those Prometheus exporters are an important part of your monitoring infrastructure, and understanding their performance and other operational details is critical for well-implemented monitoring.    

To help you with this we’ve added a number of new dashboards to Percona Monitoring and Management.

The Prometheus Exporters Overview dashboard provides a high-level overview of your installed Prometheus exporter …

In case you missed last week’s column, don’t forget to read the fairly lengthy FOSDEM MySQL & Friends DevRoom summary.

From a Percona Live Santa Clara 2018 standpoint, beyond the tutorials getting picked and scheduled, the talks have also been picked and scheduled (so you were very likely getting acceptance emails from the Hubb.me system by Tuesday). The rejections have not gone out yet but will follow soon. I expect the schedule to go live either today (end of week) or early next week. Cheapest tickets end March 4, so don’t …

In this blog post, we’ll review additional Amazon Aurora MySQL monitoring capabilities we’ve added in Percona Monitoring and Management (PMM) 1.7.0. You can see them in action in the MySQL Amazon Aurora Metrics dashboard.

Amazon Aurora MySQL Transaction Commits

This graph looks at the number of commits the Amazon Aurora engine performed, as well as the average commit latency. As you can see from this graph, latency does not always correlate with the number of commits performed and can be quite high in certain situations.
