Cost Optimization Guide

LogTrim vs Fluent Bit

Fluent Bit is a strong collector, but teams often need simpler centralized policy management for cost control.

Why this problem exists

Collector-first architectures can spread filtering logic across many agents and environments.

As rules grow, consistency and governance become harder.

Real cost and impact

Distributed rule drift can keep noisy logs flowing, reducing expected savings.

Maintenance effort grows with infrastructure scale and team turnover.

Solutions (including alternatives)

  • Use Fluent Bit when lightweight collection is the core need and you can absorb rule-management overhead.
  • Use a dedicated pre-ingestion policy layer when consistent cost control is the top outcome.
  • Preserve Datadog and S3 split-routing to separate hot search from low-cost retention.

How LogTrim solves it

LogTrim centralizes filtering and routing policy in one control path.

Teams avoid maintaining large sets of per-agent filtering config.

Example scenario

A team standardized noisy-path suppression in one place instead of patching many Fluent Bit configs.

They reduced ingest variance across environments.

Reduce your costs with LogTrim

Start with high-noise categories, keep high-signal logs in Datadog, and archive full retention in S3.
