How to Monitor MySQL Deployments with Prometheus & Grafana at ScaleGrid

Monitoring your MySQL database performance in real-time helps you immediately identify problems and other factors that could be causing issues now or in the future. It’s also a good way to determine which components of the database can be enhanced or optimized to increase your efficiency and performance. This is usually done through monitoring software and tools either built-in to the database management software or installed from third-party providers.

Prometheus is an open-source software application used for event monitoring and alerting. It can be used along with a visualization tool like Grafana to easily create and edit dashboards, query, visualize, alert on, and understand your metrics. ScaleGrid provides full admin access to your MySQL deployments – this makes it …

Re-Slaving a Crashed MySQL Master Server in Semisynchronous Replication Setup

In a MySQL 5.7 master-slave setup that uses the default semisynchronous replication setting for rpl_semi_sync_master_wait_point, a crash of the master and failover to the slave is considered to be lossless. However, when the crashed master comes back, you may find that it has transactions that are not present in the current master (which was previously a slave). This behavior may be puzzling, given that semisynchronous replication is supposed to be lossless, but this is actually an expected behavior in MySQL. Why exactly this happens is explained in full detail in the …

Managing Big Data with MySQL Can be Challenging

Author: Robert Agar

MySQL is an extremely popular open-source database platform originally developed by Oracle. It currently is the second most popular database management system in the world, only trailing Oracle’s proprietary offering. If you aim to be a professional database administrator, knowledge of MySQL is almost a prerequisite. It is an important part of the multi-platform database environment found in the majority of IT departments.

A recent addition that has added to the complexity of managing a MySQL environment is the introduction of big data. Big data is characterized by the volume, velocity, and variety of information that is gathered and which needs to be processed. It can be used to provide an organization with the business …

Error Logging in MySQL 8

Although only available as a Release Candidate, MySQL 8 is already proving itself to be a huge leap forward in many regards. Error logging is no exception. The MySQL development team just announced that they have redesigned the error logging subsystem to use a new component architecture.

The redesign will allow the filtering of log events, as well as the routing of error log output to multiple destinations, via the enabling of multiple sink components.  This will make it possible to send error log events to third-party systems for additional formatting and analysis.

In today’s blog, we’ll explore how to employ MySQL 8’s component-based error logging to achieve a variety of logging configurations. Note that all this is specific for MySQL 8 and is not available in earlier versions and also not in MariaDB. However, MariaDB has an option to write the error log to the system “syslog” on systemd-based Linux variants – …

Preview: Top MySQL 8 Features

Although there is no official software release for MySQL 8.0 as of yet, most insiders believe that it’s likely to arrive sometime in 2018.  In the meantime, Oracle has officially announced a tantalizing list of over two hundred new features!   We recently covered Replication Performance Enhancements.  Today’s blog will cover some of the other exciting enhancements we can expect when the production release of MySQL 8 hits the market.

New Database Roles

A role is a named collection of privileges that define what a user can and cannot do within a database. Roles play a vital part of database security by limiting who can connect to the server, access the database, or even access individual database objects and data.

Although prior to version 8, MySQL did provide a set of Privileges and Administrative Roles, the up-coming release will also support a set of flexible and properly …

Top Performance Metrics to Monitor on MySQL

As tables increase in size and more and more users come online, it becomes increasingly necessary to fine-tune your database server from time to time. The secret to knowing what adjustments need to be made is to perform regular monitoring. Most databases offer dozens – if not hundreds – of performance metrics that you can assess.

In the earlier blog, we showed a number of ways to determine the cause(s) of MySQL database performance issues using a couple of built-in tools. With this two blog series, we will focus on monitoring key performance metrics. In part one, we’ll:

  • examine the benefits of performance monitoring,
  • outline the main performance metric categories
  • list the monitoring tools provided by MySQL, i.e.:
    • server variables
    • the Performance Schema
