A Practical Guide to MySQL Server Monitoring for Small Teams
MySQL server monitoring is less about catching fires and more about seeing them build. This guide walks through the key metrics that reveal how your MySQL instance is trending — slow query rates, buffer pool efficiency, replication lag, and disk growth — and explains what to do when the numbers start moving in the wrong direction. You will also find a real-world example of a gradual performance issue that went undetected for weeks because no threshold was crossed. Whether you manage one server or twenty, understanding the trend matters more than the snapshot.
