Overview

What is AWS S3 Monitoring?

AWS S3 (Simple Storage Service) monitoring involves tracking the capacity and utilization of your cloud storage buckets. Because S3 is virtually infinite, monitoring focuses on metrics that impact your AWS bill and performance: the total BucketSizeBytes (how much data you are storing), NumberOfObjects, and the rate of GET/PUT/DELETE API requests made to the bucket.

Why AWS S3 Monitoring Matters

S3 is cheap until it isn't. An application bug that endlessly writes log files to an S3 bucket can silently cost thousands of dollars before you notice. Furthermore, high rates of API requests (like an unoptimized script downloading the same file millions of times) can incur massive AWS charges. Monitoring S3 ensures you track storage growth and request anomalies before you receive the monthly invoice.

✓Prevent massive billing surprises from runaway S3 uploads
✓Track object counts to understand data growth trends
✓Monitor 4xx/5xx error rates for applications accessing S3
✓Identify spikes in API requests (GET/PUT) that incur charges

Core Use Cases

Crucial for FinOps teams looking to optimize AWS costs, data engineering teams managing massive data lakes in S3, and application developers needing to ensure their apps aren't failing to upload critical files.

Features

Complete S3 Monitoring Capabilities

🗂️

Bucket Size & Objects

Track the exact gigabyte size and object count of every S3 bucket in your AWS account over time.

🔄

API Request Rates

Monitor the volume of AllRequests, GetRequests, and PutRequests to identify inefficient application code.

⚠️

Error Rate Tracking

Identify authentication issues or missing files by monitoring 4xxErrors and 5xxErrors returned by your S3 buckets.

🔔

Growth Alerts

Set thresholds to receive an alert if a bucket's size grows by an unusual percentage within a 24-hour period.

FAQ

Frequently Asked Questions

Usually, it's not the storage size, but the API requests. If a script goes rogue and makes 10 million GET requests in a day, AWS charges for every request. BigBell tracks these request rates.

Yes, we monitor the size and object counts across all S3 storage classes (Standard, Infrequent Access, Glacier).

AWS CloudWatch updates S3 storage metrics (like bucket size) once per day, while request metrics (GET/PUT) are updated every minute. BigBell aligns with these AWS intervals.
