SQL Server Monitoring Guide

As the most widely used open-source relational database in the world, MySQL is a highly effective tool for web-based software applications and data storage/management. Due to its significance and growing popularity, it is vital to know the do's and don'ts of MySQL monitoring and to keep track of any areas that impact the performance of your MySQL servers because if these issues aren’t addressed quickly, application outages are likely to occur. With MySQL servers having such a wide variety of workloads, here are some of the key areas you should be proactively monitoring. 

SQL availability 

The most important SQL metric to monitor is the availability of MySQL servers. MySQL downtime needs to be avoided at all costs, but network outages or application/device failures can force MySQL servers to be out of service. Keeping a close eye on metrics such as database availability (i.e. uptime), threads_connected, max_used_connections and aborted_ connects will ensure you are utilizing the benefits of MySQL, rather than being in the dark due to any errors or log file issues. 

Security of users

If you have users based in multiple locations that can connect to MySQL, it automatically means your servers are prone to security breaches. Monitoring the presence of potentially insecure users is vital to maintaining a healthy MySQL environment. Here are a few security tips to implement that will keep your MySQL servers safe: 

  • Give MySQL users a literal host value, rather than ‘%
  • Make sure you aren’t granting MySQL users with excessive privileges and use different terms instead of ‘root’ that will enhance your security efforts 
  • Monitor Client Access License to have direct insight into your connection count

Error and transaction logs

MySQL logs are comprised of statistics regarding server status including start and stop time as well as critical errors that happen while the server is actively running. By keeping track of error logs, you’ll be able to view the status of MySQL before any system crashes occur. And if you’re looking to increase bandwidth within your databases, monitoring transaction logs will ensure you have space to do so without any loss in server performance. 

Server configuration

Servers can be in an ideal state for multiple weeks and one day, something mysteriously goes awry. When a server issue is not easily identifiable via an alert or notification, it is often the result of a recent change in configuration, which plays a vital role in server performance. Be sure to analyze any new additions into your MySQL environment to see how they may be related to server-impacting issues.
