Welcome to the first day of the Percona Live Open Source Database Conference 2017, and the first set of Percona Live keynotes!

It’s a beautiful day in Santa Clara, but we don’t know because we’re inside the Hyatt Regency Convention Center listening to various rock stars in the open source database community talk about open source technologies.

In honor of the upcoming MariaDB M17 conference in New York City on April 11-12, we have enhanced Percona Monitoring and Management (PMM) Metrics Monitor with a new MariaDB Dashboard and multiple new graphs!

The Percona Monitoring and Management MariaDB Dashboard builds on the efforts of the MariaDB development team to instrument the Aria Storage Engine Status Variables related to Aria Pagecache and Aria Transaction Log activity, the tracking of Index Condition Pushdown (ICP), InnoDB Online DDL when using ALTER TABLE ... ALGORITHM=INPLACE, InnoDB Deadlocks …

In this blog post, we’ll discuss services monitoring using probabilistic fault detection.

Let’s admit it, the task of monitoring services is one of the most difficult. It is time-consuming, error-prone and difficult to automate. The usual monitoring approach has been pretty straightforward in the last few years: setup a service like Nagios, or pay money to get a cloud-based monitoring tool. Then choose the metrics you are interested in and set the thresholds. This is a manual process that works when you have a small number of services and servers, and you know exactly how they behave and what you should monitor. These days, we have hundred of servers with thousands of services sending us millions of metrics. That is the first problem: the manual approach to configuration doesn’t work.

That is not the only problem. We know that no two servers perform the same because no two servers have exactly the …

If you've been watching the evolution of database technologies over the past few years, you've seen how quickly JSON has quickly cemented its position in major database servers. Due to its use in the web front-end, JSON has overtaken XML in APIs, and it’s spread through all the layers in the stack one step at a time.

Most major databases supported XML in some fashion for a while, too, but developer uptake wasn’t universal. JSON adoption among developers is nearly universal today, however. (The king is dead, long live the king!) But how good is JSON support in the databases we know and love? We’ll do a comparison in this blog post.

Take Percona’s blog poll on what database engine you are using to store time series data.

Time series data is some of the most actionable data available when it comes to analyzing trends and making predictions. Simply put, time series data is data that is indexed not just by value, but by time as well – allowing you to view value changes over time as they occur. Obvious uses include the stock market, web traffic, user behavior, etc.

With the increasing number of smart devices in the Internet of Things (IoT), being able to track data over time is more and more important. With time series data, you can measure and make predictions on things like energy consumption, pH values, water consumption, data from environment-aware machines like smart cars, etc. The sensors used in IoT devices and systems generate huge …
