MySQL Performance Tuning Tips for the Shopping Season

With Halloween all but a distant memory, the time has come to turn our attention to the upcoming holiday season. First, Thanksgiving, then Black Friday and Cyber Monday, culminating in the Christmas/boxing week shopping bonanza. For business owners, this time of the year marks the long-awaited year’s end profit taking. For some DBA’s, it brings fear, trepidation, and even sleepless nights toiling away to bring systems back online.

Thankfully, this need not be the case. With a little proactive tweaking of MySQL performance variables, you can insulate your database server(s) against the onslaught of increased demand that the shopping season brings.

Tip #1: Determine the Maximum Number of MySQL Connections

A good starting estimate for the maximum number connections on MySQL is one for every five requests to your web server. A few of those five requests to your web server will be for resources like CSS style sheets, …

Top Performance Metrics to Monitor on MySQL (Connections & Buffer Pool Usage)

As a DBA, your top priority is to keep your databases and dependent applications running smoothly at all times. To this end, your best weapon is judicious monitoring of key performance metrics. In a perfect world, you’d want to be up-to-date regarding every aspect of your database’s activity – i.e. how many events occurred, how big they were, precisely when they happened and how long they took.

There certainly is no shortage of tools that can monitor resource consumption, provide instantaneous status snapshots, and generate wait analysis and graphs. The challenge is that some metrics can be expensive to measure, and, perhaps even more importantly, they can require a lot of work to analyze.

The purpose of Part-2 of the blog series is to narrow down the field to those performance metrics that provide the most value for the effort as well as present some tangible ways to capture and study them. It is by tracking the most useful …

Monyog MySQL Monitor v8.3.0: Introducing Trend Graph Analysis

Monyog MySQL Monitor v8.3.0 is a feature-rich release which adds a large number of user requests for quick access to relevant monitoring information, for ‘cross-plotting’ multiple servers in a unified chart and more.  Additionally, it adds a number of non-critical bug fixes.

Changes as compared to Monyog MySQL Monitor v8.2.0 include: Features:

Added option to set a distinct email distribution list for warning alerts and critical alerts. Trend Graph Analysis: Added option to group a single metric (which one you find most important) from different servers into one unified chart. This allows you to visually analyse a metric across servers at various points in time.

Choose the monitor group >> Click on the trend graph icon next to the metric as shown below.

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

Troubleshooting MySQL Performance Issues

Despite your very best efforts, as tables increase in size and more and more users come online, sluggish MySQL performance eventually rears its ugly head. When that happens, you may be tempted to shrug it off as part of doing business. Don’t. By understanding the mechanisms behind database slowdowns and by methodically attacking the problem, you can home in on the culprit(s) and remedy the issues in a timely manner, before your business suffers substantial losses as a result.

The purpose of this blog is to assist you in determining the cause(s) of MySQL database performance issues using a couple of built-in tools.

Why Database Performance Slows Down

It’s no secret that database performance tends to degrade over time. While it’s easy to point the finger at the number of concurrent users, table scans, and growing tables, the reality is more complex than that. The most common reason for slow database performance is …

Monitoring MySQL Problematic Queries

This blog describes how to identify queries that cause a sudden spike in system resources as well as the user and host who executed the culprit query using the Monyog MySQL Monitor and Advisor.

How many times have you seen a system go live and perform much worse than it did in testing? There could be several reasons behind bad performance. For instance, a slow running query in MySQL can be caused by a poor database design or may be due to higher-than-normal latency in network communication. Other issues such as using too few or too many indexes may also be a factor. This blog will identify the types of poorly performing queries and outline some concrete strategies for identifying them using monitoring. Finally, some tips for improving performance will be presented.

The Effects of Misbehaving Queries

Typically, misbehaving queries will result in two possible outcomes: high CPU usage and/or slow execution. The two …
