WHAT WATCHLOG COLLECTS

Complete MySQL observability.

The Watchlog Agent collects these metrics automatically once the MySQL integration is enabled.

Max_used_connections
Max Used Connections
Peak simultaneous connections since last restart
Slow_queries rate
Slow Queries/sec
Queries exceeding long_query_time per second
Aborted_clients

Connections dropped without clean disconnect
Aborted_connects
Aborted Connects
Failed connection attempts (wrong password, etc.)
1 - Innodb_buffer_pool_reads / Innodb_buffer_pool_read_requests
InnoDB Buffer Pool Hit %
Percentage of reads served from InnoDB buffer cache
Table_locks_waited
Table Lock Waits
Table-level lock waits since server start
Com_select rate
Query Rate (SELECT)
SELECT statements per second
Com_insert|update|delete rate
Write Rate (INSERT+UPDATE+DELETE)
Combined write operations per second
Seconds_Behind_Master
Replication Delay
Seconds the replica lags behind the primary
Bytes_sent | Bytes_received
Bytes In / Out
Network throughput for MySQL connections
LIVE DASHBOARD

MySQL at a glance.

A pre-built MySQL dashboard activates the moment you enable the integration — no configuration required.

USE CASES

What engineers use MySQL monitoring for.

⌇
Slow query identification
Surface queries exceeding long_query_time and correlate them with traffic patterns or recent schema changes.
▣
Connection limit management
Track threads_connected against max_connections and get alerted before connection exhaustion causes application errors.
◈
InnoDB buffer pool tuning
Monitor buffer pool hit rate continuously. A drop below 95% usually signals a need for more RAM or a missing index.
⊕
Replication health
Monitor Seconds_Behind_Master across all replicas. Alert the moment a slave starts drifting.
WHY WATCHLOG

Fewer blind spots. Earlier warnings.

Engineering teams that monitor MySQL with Watchlog catch failure signals before they become incidents.

  • ✓Catch slow queries before users notice latency on critical paths
  • ✓Alert on aborted clients — often a sign of connection pool misconfiguration
  • ✓Track InnoDB buffer pool efficiency to time memory upgrades correctly
  • ✓Know when replication drifts before read replicas return stale data
  • ✓Correlate query rate spikes with deploys or batch jobs
QUICK SETUP

MySQL monitoring in under 2 minutes.

No YAML. No config files. The Watchlog Agent detects MySQL on your host and begins collecting immediately.

01
Install the Watchlog Agent
One command on your MySQL host. The agent auto-detects MySQL on port 3306.
02
Enable MySQL integration
Go to Watchlog → Integrations → MySQL and grant the agent a read-only monitoring user.
03
See metrics in under 60s
Connection stats, slow query rates, and InnoDB metrics appear within one minute.
INSTALL WATCHLOG AGENT
sudo apiKey="$WATCHLOG_API_KEY" server="$WATCHLOG_SERVER" MEMORY="300M" bash -c "$(curl -L https://watchlog.io/ubuntu/watchlog-script.sh)

The agent automatically detects MySQL running on your host and begins collecting metrics immediately.
