MySQL integration

The MySQL integration provides database performance monitoring for MySQL instances, whether standalone, replicated, or clustered.


What it’s for	Monitoring query performance, connections, replication, and InnoDB health
Who uses it	DBAs, backend developers, DevOps teams managing MySQL databases
Under the hood	One of the most mature integrations, refined over years of real-world use

Metrics collected

Queries — QPS, slow queries, query types
Connections — Active, max, threads
InnoDB — Buffer pool, I/O, row operations
Replication — Lag, status, errors

Trade-offs

Best for: MySQL databases—standalone, replicated, or clustered

Pros	Cons
Pre-built dashboards: overview, replication, InnoDB	Requires monitoring user with GRANTs
Pre-built alerts: connections, replication lag	Version-specific metric differences
Query performance and slow query visibility
InnoDB buffer pool and I/O metrics
Mature, battle-tested integration

Learning path

Deploy this integration step by step.

MySQL integration

MySQL is everywhere, and the MySQL integration gives you the visibility to keep it healthy. Query metrics show you queries per second, slow query counts, and breakdowns by type (SELECT, INSERT, UPDATE, DELETE). This tells you what your database is actually doing.

Connection metrics track active connections versus your configured maximum. Running out of connections is a classic MySQL failure mode, and you want to see it coming.

InnoDB metrics are where performance analysis lives. The buffer pool hit ratio is critical.

If it’s low, your working set doesn’t fit in memory and performance suffers. I/O metrics, row operations, and lock waits help you understand InnoDB behavior.

For replicated setups, you get replication lag and status. Catching replication problems early prevents nasty surprises during failovers.

Setup requires a monitoring user with specific permissions. The documentation gives you the exact GRANT statements to run.

This is one of the most mature integrations, refined over years of real-world MySQL monitoring.
