MySQL is the second most popular relational database management system (RDBMS) after Oracle. It is endearing facts like being a free and open-source database platform – while still offering advanced data management features and a robustness few others can match – that have contributed to its being favored as such.
This popularity also means there will always be a market for MySQL monitoring tools that database administrators (DBAs) can use to get the maximum performance out of their databases.
Here is a summary list of the five best MySQL monitoring tools:
- SolarWinds Server & Application Monitor – FREE TRIAL – this tool comes from the market leader in the server monitoring market and works with almost all databases, not just MySQL, allowing for the ultimate integrated database administration experience.
- Paessler MySQL Monitoring – this is a cloud-based network infrastructure monitoring tool that uses numerous sensors to help administer MySQL databases as well as the hardware and software solutions that support them.
- ManageEngine Application Manager – here we have a popular suite of software and hardware monitoring tools for enterprise database solutions like Oracle, MS SQL, and MySQL which makes it a great choice for businesses with hybrid data storage systems.
- Percona Monitoring and Management Tool – this is a free and open-sourced database monitoring, management, and security solution for all flavors of MySQL.
- AppDynamics MySQL Performance Monitoring – a comprehensive database monitoring tool that works round-the-clock and gives in-depth insights into their performances as well as dependable forecasts.
What are the main metrics MySQL monitoring tools keep track of?
A good MySQL monitoring tool reads the pulse of a MySQL database and server system by tracking four main metrics:
- Queries: it is important to keep an eye on the performance of every single query to ensure there is an optimal performance in execution time. On the other hand, databases need to be monitored for inefficient joins between tables, insufficient indexes, and unnecessarily complex SQL statements which should trigger alerts.
- Capacity issues: database performance can be affected by issues with the hardware it sits on like low processing power, slow hard disk read-write times, hardware misconfiguration, low disk space, and low memory.
- Conflicts among users: when there are many users on a database they could run queries that interfere with one another's' activities. If one user's database query takes too long, it could cause a page or row lock. Transactional locks or deadlocks could also keep other users out until they are released. These tools help identify such conflicts.
- Configuration issues: improper hard disk configurations can cause issues. To avoid such performance issues, a tool can monitor for issues like insufficient buffer sizes or the absence of a query cache.
Armed with input from monitoring tools, a DBA can quickly resolve issues and get things back on track.
The best MySQL monitoring tools
SolarWinds Server & Application Monitor (SAM) is a software-as-a-service (SaaS) platform with a web-based user interface; it deploys lightweight agents for specific tasks via multiple configurations. This makes it easy to install and use. It can be used to monitor MySQL databases in the cloud, local, or hybrid networking architecture environments.
SAM stores both real-time and historical data that can be used to pinpoint, analyze, and resolve current performance issues as well as make forecasts. It also uses multiple methods to protect sensitive data which helps with achieving GDPR and SOC 2 compliance.
Some more features include:
- This is a tool that monitors ALL servers but it can be made even more detailed and powerful with the Database Performance Monitor extension which can also work with MySQL databases. Meanwhile, SolarWinds Database Performance Analyzer for MySQL and MySQL Performance Monitoring integration tools specifically manage MySQL databases.
- With the MySQL performance monitoring tool, DBAs can measure latency and throughput times and receive warnings for errors in index usage and execution plans.
- It offers 24/7 real-time monitoring to help attain Key Performance Indicators (KPIs) goals for availability, deployment frequency, reduced failed deploys, and short change lead times.
- The tool makes instant recommendations on which server configurations to tweak and finds queries with potentially erratic behavior.
- The Query Analyzer is a root cause analysis tool that shows a master-detail view of all servers and has the capability of drilling-down into queries, EXPLAIN plans, and cross-correlating it with other metrics like I/O and CPU. Alternatively, it can drill down from a global view to a single problem query on a single server.
- The tool can monitor and classify data on MySQL queries, users, databases, processes, hard disks, and processors, among many other system components. It can also dissect these queries, users, and databases to compare them for trend and delta reports.

2. Paessler MySQL Monitoring
Paessler AG – the makers of PRTG, a cloud-hosted network, and infrastructure monitoring tool – offers predefined sensors for every important database manufacturer, including MySQL, with the help of its MySQL v2 Sensor.
Features included with this monitoring tool are:
- PRTG can monitor Oracle, PostgreSQL, Microsoft SQL Server, as well as MySQL which makes it ideal for a complex database environment.
- The tool's dashboard is flexible, customizable, clean, and easy to use – it has tabs for quick access to features like notifications, alarms, and logs to effortlessly keep on top of issues.
- PRTG is also easy to set up which cuts the time needed to deploy and start running; once done, admins can use the default, preconfigured sensors, or configure their own for unique scenarios with the help of APIs.
- It can show execution times of requests – going from connection buildup, to query execution, to transaction handling, and disconnection times of a defined query. In the case of latency, it can then be tweaked for optimal performance.
- The tool can, for example, show the number of rows that were affected or added by a query like a SELECT statement when working with data tables and transactional insights are required for troubleshooting issues caused during execution time.
- When it comes to monitoring, PRTG minimizes query and return times which results in a real-time view of MySQL databases.
PRTG offers a free download of their unlimited version of the tool for 30 days after which the tool reverts to a free version.
3. ManageEngine Applications Manager
ManageEngine Applications Manager is another suite of software and hardware monitoring tools that holds a large share of the market. This tool has the ability to manage JDBC databases like Oracle, MS SQL, and MySQL.
Together, these tools help DBAs manage and monitor the performance and availability of their MySQL databases with features like:
- DBAs can monitor critical performance parameters of their databases to maximize uptime. Some key performance parameters monitored include: connection times, request times, thread details, query hit ratio, database and index sizes, and replication details.
- It monitors MySQL query performance by keeping track of a set of specific critical queries and associating alarms to them, to get instant notifications in case they perform abnormally.
- Similarly, it can be used to keep a check on the latency of data syncing – and flag delays in synchronization of data between database servers – depending on the type of replication topology employed.
- It is also a forecasting tool – Applications Manager's MySQL monitor compares historical performance reports of database servers to visualize future performance trends. These machine-learning powered forecast reports allow DBAs to predict future growth and utilization of their MySQL databases and then plan for resource upgrades as well as load distribution.
- MySQL Monitoring also offers the flexibility to create custom reports that can be scheduled to run at required intervals.
All in all, Applications Manager's MySQL Management tool enables users to gain end-to-end visibility into the performance of their MySQL servers with its robust managing, monitoring, alerting, and analytical capabilities.
