Overview

One of the main challenges that database administrators face is to identify time consuming queries and determine how best to tune them. To accomplish this, database administrators often rely on having a trend analysis of workloads and queries, including query durations.

 

The Query Performance Insight feature in Azure Database for MySQL – Flexible Server provides the ability to perform intelligent query analysis for databases. The most preferred insights related to workload patterns and long-running queries. This information can help identify which queries you need to optimize to improve overall performance and ensure that available resources are used most efficiently.

 

Query Performance Insight is designed to help you spend less time troubleshooting database performance, with such information as:

  • The top N long-running queries and their trends.
  • Query details included query text and the history of execution with minimum, maximum, average, and standard deviation query times.
  • Utilization of resources (CPU, memory, and storage).

This blog post includes a video that provides an overview of how MySQL slow query logs, the Log Analytics tool, and workbooks templates help to visualize Query Performance Insight data in Azure Database for MySQL - Flexible Server.

 

Note: For step-by-step details on how to implement this set up, in our product documentation, see the tutorial Query Performance Insight for Azure Database for MySQL - Flexible Server.

Summary

While it’s not the easiest task to accomplish, database performance tuning is critical for ensuring the health of the database. Query performance is dependent on a range of factors, such as the database model, the kind of information you need to fetch, etc. Using Query Performance Insights, slow query logs, Log Analytics, and Azure Monitor Workbooks, you can create rich visual reports to make query analysis more efficient and less time consuming.
