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	Uses the mysqld exporter to read server status and InnoDB metrics

Metrics collected

The integration collects the metric groups that matter most for MySQL:

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

What to know

Prebuilt dashboards: overview, replication, InnoDB
Prebuilt alerts: connections, replication lag
Query performance and slow query visibility
InnoDB buffer pool and I/O metrics

MySQL is everywhere, and this integration keeps it healthy. Query metrics show queries per second, slow queries, and a breakdown by type, so you can see what the database is doing.

Connection metrics track active connections against your maximum, since running out is a classic MySQL failure. InnoDB metrics are where performance analysis lives, especially the buffer pool hit ratio: a low ratio means your working set doesn’t fit in memory. For replicated setups, you also get replication lag and status.
