  • What is MySQL database?

    MySQL databases are among the most popular open-source relational database lol世界总决赛下注 system (RDBMS). RDBMSs are useful because they can store different types of data in related tables, which provides a structure for how data is organized and searched. “SQL” is an abbreviation for “Structured Query Language,” a programming language that enables data to be created, retrieved, and modified from RDBMSs, in addition to limiting user access to the database.

    In addition to functioning as a database server, MySQL has other administrative applications. It can, for instance, be used to integrate with operating systems to organize workstation storage into relational databases, provide network access, manage user accounts, help create backups, and test database integrity. RDBMSs like MySQL are commonly used for storing large amounts of data—including complex financial, personnel, and manufacturing information—and are popular for their ease of implementation and use as compared to legacy systems like hierarchical and network databases.

  • Why should I monitor MySQL?

    Many businesses and organizations rely on the power and versatility MySQL systems provide to run their websites and storage systems. For instance, databases like MySQL are the backbone of e-commerce sites, running multiple tasks and processes to ensure business-critical web applications are operating optimally.

    A robust MySQL performance monitoring tool is necessary to track and manage the health of vital infrastructure systems and can often provide valuable MySQL query statistics and insights to help improve troubleshooting times. MySQL database performance metrics can reveal underlying resource or system issues that have otherwise gone undetected, and MySQL query monitoring tools can help to pinpoint the exact requests causing issues. MySQL monitoring tools offer necessary visibility into your systems, so you can understand precisely how to start fixing problems as they arise.

  • What are key performance statistics in MySQL?

    Changes in database speed and performance have wide-reaching impacts across entire companies. A MySQL performance monitor tool can collect a huge number of performance metrics exposed by MySQL databases, and by focusing on a few key metrics, you gain a deeper understanding of your system performance and how to improve it. Comprehensive MySQL monitoring should focus on four primary areas to help keep databases operating smoothly:

    • Query throughput. The efficiency of a system can be an important indicator of database health and performance, and monitoring MySQL queries can provide valuable insight into how databases are processing and responding to requests. While the number of queries will fluctuate over the course of the day, sudden changes in query volume are often the sign of a serious issue. The Questions counter in the built-in MySQL monitor provides a user-friendly view of all statements received by client applications, and examining read and write commands can shed a light on potential bottlenecks and problem areas.

    • Query latency. Query latency, or execution performance, is also important to track, because small changes in database latency can have large impacts on resource utilization and performance. The innate MySQL monitor includes a Slow_queries metric, which counts the number of times the run time of a database query exceeds the baseline performance threshold. If average latency is beginning to increase, it could be a sign of resource constraints, changes in client query patterns, or database inefficiencies. Further, sudden increases in the number of query errors reported by the MySQL monitor are typically a sign of a larger problem within the database or with the client-side application.

    • Connections. Databases support a limited number of client connections. Once all connections are in use, they’ll refuse new ones, which can impede important client transactions and impact the company’s bottom line. Monitoring the number of client connections is crucial to ensure your systems have sufficient capacity. The Threads_connected metric and configured connection limit are two numbers to keep an eye on.

    • Buffer pool usage. When caching data for database tables and indexes, MySQL uses a storage engine, InnoDB, to access a part of system memory called the buffer pool. While monitoring performance metrics helps detect issues when they occur, monitoring resource metrics like buffer pool usage can be useful when moving from the detection to investigation stages of troubleshooting. If database performance is beginning to suffer at the same time the disk I/O is increasing, it can indicate the size of the buffer pool resources need to be expanded.

  • How to view MySQL performance?

    While MySQL’s built-in monitor is useful for ad hoc performance checks and query tuning, many of the metrics exposed by MySQL database can be accessed programmatically and routinely. Therefore, the most efficient way to view MySQL performance is by adopting a robust MySQL performance monitoring tool. These software solutions integrate with MySQL systems to collect application- and system-level metrics, cross-examine metrics from different systems, and help investigate the root cause of performance issues.

    The best MySQL performance monitors include powerful graphic and visualization capabilities to provide an at-a-glance understanding of performance and resources, which also contributes to speeding resolution time. Leading MySQL monitors and monitoring platforms also include alerting systems to notify admins when key metrics approach and cross critical performance thresholds.

    While recently changed queries are often the cause of performance issues, this isn’t true in all instances. MySQL monitors are necessary tools for investigating query issues and resource constraints, and for keeping your systems operating smoothly.

    A MySQL performance monitoring tool can also help manage buffer pool usage. By default, buffer pools are small (set at 128 MiB), but on database servers, the majority of physical memory—MySQL advises as high as 80 percent—can be dedicated to buffer pools. However, it’s important to remember memory overhead can actually increase overall memory footprint beyond the allocated buffer pool resources—so running out of physical memory will cause database performance to suffer dramatically. Tracking metrics like buffer pool size, utilization, and efficiency can be useful for ensuring systems are adequately provisioned and secure.

  • How do the MySQL monitoring tools in DPM work?

    A MySQL monitor like SolarWinds Database Performance Manager (DPM) provides a comprehensive set of tools for database admins.

    DPM’s MySQL monitoring tools collect exposed MySQL database performance metrics and organize them into preconfigured dashboards designed to get you monitoring the most important metrics right out of the box. This allows you to track thousands of distinct metrics about your applications, databases, and infrastructure and to organize and filter those metrics, so they can be examined and analyzed. Clicking on a metric in a table, for instance, will bring you to a more detailed breakdown for the metric, including performance over time and host relationships.

    DPM also allows you to create customized dashboards with the click of a button, which can be especially useful when correlating metrics from different systems and further enables you to tailor your MySQL monitoring to the specific needs of your deployment.

    In DPM, the Metrics page displays measurements taken from individual exposed metrics, while also allowing you to filter and sort the results by specific metric names and hosts. DPM collects information about MySQL database performance metrics with one-second granularity, which the tool uses to construct detailed historical archives of performance data that can be analyzed and dissected for deeper understandings.

    DPM also collects information about database queries and can assist in database optimization and query tuning operations. The software is designed to make data convenient and usable to you, allowing you to sort through queries by category—such as those reporting errors, missing indexes, or slow response times—or by when the query first appeared. Features like Top Queries show a master-detail view across servers in your application, with per-second drill-down into samples of queries, EXPLAIN plans, and cross-correlations with other metrics like I/O and CPU. You can thin-slice queries, users, and databases, and compare across time periods quickly for before-and-after change analysis.

    Lastly, DPM’s MySQL monitor includes robust graphs and visualizations. If you have dashboard systems you already prefer, there’s no need to worry—DPM’s set of MySQL monitoring functions and capabilities can integrate via a free downloadable plugin with a variety of open-source analytics and visualization solutions, including Grafana. With this, you can access the thousands of metrics DPM helps to monitor and manage, but from the familiarity of the same dashboard your teams know and recognize.
