Since the performance schema is the source of metrics for most tools, the majority of these tools offer very similar visibility. Such monitoring solutions gather metrics from the MySQL Performance Schema which contains metadata about a MySQL instance-everything from queries and errors to low-level storage metrics. This information is then translated into metrics and submitted to a monitoring solution, which allows you to visualize and set up alerts whenever they deviate from their normal state. Each response contains information about the MySQL system.
MySQL monitoring tools make regular requests to retrieve MySQL performance statistics. Now that we’ve covered why monitoring MySQL performance is so important, let’s explore how it actually works. No matter the cause, having monitoring tools at our disposal significantly cuts down on MTTR and getting the system back to a healthy state. If, on the other hand, the database was healthy, we knew to look elsewhere. If the database was unhealthy, my team knew that was where we needed to focus our efforts. When monitoring is available though, it’s easy to determine if the issue originates in the database. On many occasions, the service my team and I were working on began throwing 5XX response codes. In such cases, MySQL charts help pinpoint the cause by revealing when the issue appeared. For example, your services may be leaking database connections. Since databases are often the center of most systems, MySQL frequently ends up being a bottleneck for other services. This is particularly important with MySQL.
A good monitoring tool will also send alerts when metrics deviate from a steady state so that you can quickly intervene and avoid potential outages or other customer-impacting issues. MySQL monitoring tools achieve this through low-level system metrics that offer an overview of your deployment. Not only do metrics allow you to determine whether your MySQL database is healthy, they also help prevent performance issues. It’s an inexpensive solution that delivers companies great ROI. If your customer base is growing or you’re experiencing frequent performance issues with your MySQL deployment, you need a database monitoring tool. In this blog post I’ll review some of the best MySQL monitoring tools available that can help measure and improve database performance. But choosing a database monitoring solution can be tough due to the vast number of solutions available, each with their own pros and cons. A good monitoring tool alerts on issues before they impact end users and helps reduce the MTTR of incidents when they do occur.
