Overview

What is AWS RDS Monitoring?

AWS RDS (Relational Database Service) monitoring involves tracking the performance and health of managed databases (like PostgreSQL, MySQL, SQL Server, and Amazon Aurora). Because you don't have access to the underlying OS on RDS, monitoring focuses on AWS-provided metrics: CPU Utilization, Freeable Memory, Read/Write IOPS, Storage Space, and Database Connections.

Why AWS RDS Monitoring Matters

The database is the beating heart of most applications. If your RDS instance runs out of Freeable Memory, or exhausts its allocated EBS IOPS, query latency will skyrocket. This causes web servers to wait, request queues to fill, and the entire application to crash. Proactive RDS monitoring ensures you scale your database instance class or storage tier *before* the bottleneck impacts your end users.

✓Prevent application downtime caused by database connection limits
✓Identify when you are hitting AWS EBS IOPS limits
✓Detect slow memory leaks causing low Freeable Memory
✓Ensure you have enough Free Storage Space to avoid database locks

Core Use Cases

Vital for Database Administrators (DBAs) managing production workloads, and DevOps teams needing to ensure their auto-scaling web tiers don't overwhelm the backend RDS instance with too many connections.

Features

Complete RDS Monitoring Capabilities

🔌

Connection Tracking

Monitor active DatabaseConnections and set alerts before you hit the RDS max_connections limit.

⚡

IOPS & Latency

Track Read/Write IOPS and DiskQueueDepth to determine if you need to upgrade to Provisioned IOPS storage.

🧠

Freeable Memory

Ensure your database has enough RAM for caching queries by constantly tracking the FreeableMemory metric.

🔔

Storage Alerts

Receive critical alerts when FreeStorageSpace drops below 10%, preventing the database from locking up.

FAQ

Frequently Asked Questions

It depends on the engine, but generally, if Freeable Memory drops consistently near zero, your database is relying on slow disk swaps. It is time to upgrade the instance size.

This usually indicates an I/O bottleneck. Check the DiskQueueDepth and IOPS metrics in BigBell. You may have exhausted your RDS storage burst balance.

Yes, BigBell fully supports monitoring Amazon Aurora clusters, tracking both the Writer and Reader instances, as well as Aurora Serverless metrics.
