What Chronosphere Can Do For You

Chronosphere is the observability platform built for control.

Chronosphere’s observability platform reduces data volumes and associated costs by 60% on average, while saving developers thousands of hours.

With Chronosphere’s Fluent Bit-based Telemetry Pipeline, teams can standardize, optimize, and simplify observability and security log data–transforming logs at the source and routing them to any destination without lock-in.

Who We Are

Platform + Pipeline for Exceptional Control

Fluent Bit vs. OpenTelemetry Collector - Why Not Both?
Fluent Bit and OpenTelemetry Collector are often seen as competing solutions—but that’s not the full story. Many teams successfully use both, but figuring out when and how to do that isn’t always obvious.
This session breaks down the top questions from Fluent users and customers:

  • When does it make sense to use Fluent Bit, OpenTelemetry Collector, or both?
  • How do their strengths compare for different telemetry types?
  • What are the key things to know before deploying either?

Open source observability isn’t about picking winners—it’s about making the right tradeoffs for your needs. Interoperability gives us options, and options give us power. As vendors and contributors, our job isn’t to build walls—it’s to build bridges.
