Why monitor MySQL?

MySQL is the world's most popular open-source relational database, powering millions of applications from startups to Fortune 500 enterprises. Monitoring MySQL is essential to detect slow queries, prevent connection pool exhaustion, track replication lag, and optimize storage usage. Xitoring's MySQL integration provides deep visibility into your database performance.

Metrics

What we monitor

Queries per Second

Rate of SELECT, INSERT, UPDATE, and DELETE queries.

Active Connections

Number of currently active connections to MySQL.

Slow Queries

Count of queries exceeding the slow query threshold.

Replication Lag

Seconds behind the master in replication.

InnoDB Buffer Pool

Buffer pool utilization and hit ratio.

Thread States

Distribution of thread states (running, sleeping, locked).

Table Locks

Rate of table lock waits and immediate grants.

Temporary Tables

Rate of temporary tables created on disk.

Bytes Sent/Received

Network throughput to and from MySQL.

Aborted Connections

Failed connection attempts and aborted clients.

Triggers & Alerts

Configurable alert triggers

Set up custom triggers in your dashboard to get notified the moment MySQL metrics cross your defined thresholds.

MySQL monitoring trigger configuration dashboard

Active Connections

critical

Fires when active connections approach max_connections, risking new connection refusal and application errors.

Replication Lag

critical

Triggers when replication falls behind, risking data inconsistency between master and replicas.

Slow Queries

warning

Alerts when slow query count exceeds threshold, indicating performance degradation.

InnoDB Buffer Pool

warning

Fires when buffer pool hit ratio drops, indicating excessive disk I/O.

Aborted Connections

warning

Triggers on connection failure spikes, indicating authentication or network issues.

Table Lock Waits

critical

Alerts when lock contention increases, degrading query performance.

Importance of MySQL Monitoring

MySQL handles critical data for millions of applications. Without proper monitoring, slow queries, replication drift, and connection exhaustion can lead to outages and data inconsistency.

Detect slow queries before they impact user experience
Prevent connection pool exhaustion with threshold alerts
Monitor replication for data consistency across replicas
Track InnoDB performance for optimal storage engine health
Identify lock contention and query bottlenecks early
