Amazon S3 Storage Lens | Metrics Overview

Amazon S3 Storage Lens provides organization-wide visibility into object storage usage and activity trends. It delivers metrics and recommendations to help twtech  optimize costs and apply data protection best practices.

 Types of Metrics in S3 Storage Lens

S3 Storage Lens metrics are categorized into two groups:

1. Usage Metrics (Free Tier)

These give insight into how much storage twtech is using, how it's distributed, and how it changes over time.

Key Usage Metrics:

• Total storage (GB/TB)
• Object count
• Average object size
• Storage by:
• Storage class (e.g., Standard, Infrequent Access)
• Region
• Bucket
• Prefix
• Number of delete markers
• Non-current version storage (for versioned buckets)

2. Activity Metrics (Advanced Tier – Paid)

These show how often and how intensively the data is being accessed or modified.

Key Activity Metrics:

• PUT, GET, DELETE request counts
• Bytes uploaded/downloaded
• 4xx and 5xx errors
• First Byte Latency (GET/PUT requests)
• Request size (bytes)

 Activity metrics are only available in the Advanced metrics and recommendations tier.

 How Metrics Are Aggregated

Metrics are calculated and reported:

• Daily
• Across entire organization, accounts, or individual buckets/prefixes
• Stored for 15 months (Advanced tier only) for historical analysis and trend tracking
