Database Monitoring

Monitor database connectivity and health

Monitoring

Database monitors go beyond simple port checks by actually connecting to your database and executing a test query. This ensures the database is not just accepting connections, but is actually responsive and operational.

Supported Databases

MySQL

Port 3306

mysql

PostgreSQL

Port 5432

postgresql

Redis

Port 6379

redis

MongoDB

Port 27017

mongodb

Elasticsearch

Port 9200

elasticsearch

RabbitMQ

Port 5672

rabbitmq

Configuration

Connection String

Database connection string or URL.

# MySQL
mysql://user:password@host:3306/database

# PostgreSQL
postgresql://user:password@host:5432/database

# MongoDB
mongodb://user:password@host:27017/database

# Redis
redis://user:password@host:6379

Test Query

Optional query to execute to verify database responsiveness.

-- MySQL / PostgreSQL
SELECT 1

-- Redis
PING

Timeout

Maximum time to wait for connection and query execution.

Security Best Practices

• Create a dedicated read-only user for monitoring
• Limit network access to only the monitoring server
• Store credentials securely (use environment variables)
• Use SSL/TLS connections when possible

Best Practices

Use a dedicated monitoring user with minimal permissions
Keep test queries lightweight to avoid impacting performance
Set appropriate check intervals (60-300 seconds for databases)
Monitor both primary and replica databases separately
