Otel Collector vs Prometheus | Krisztian Fekete

OpenTelemetry (OTel) is everywhere, but with its increasing popularity, it’s easy to get lost in the buzz and confusion surrounding it. Krisztian Fekete, an experienced former SRE and current expert in designing telemetry pipelines, takes a deep dive into the OpenTelemetry ecosystem, demystifying its components and providing valuable insights into how to use it effectively in production environments.
While many see OpenTelemetry as a "silver bullet" and believe that OTel collectors should replace everything from Prometheus instances to telemetry agents, Krisztian highlights the critical aspects that often get overlooked, such as missing functionalities and potential failure modes when adopting it uncritically.
In this session, Krisztian draws from his experience monitoring tens of millions of users with traditional Prometheus stacks and now designing telemetry solutions at scale. He’ll guide SREs through the decision-making process, helping them understand the pros and cons of various telemetry tools and offering practical advice on how to select the right solutions for the challenges at hand.
Key Topics:
Understanding the different OpenTelemetry tools, APIs, and SDKs
The pros and cons of using OpenTelemetry collectors vs. other tools
Common misconceptions and pitfalls in OpenTelemetry adoption
Insights from monitoring tens of millions of users with Prometheus
How to design scalable telemetry pipelines using OpenTelemetry
This talk is ideal for SREs and anyone involved in choosing telemetry tools, as Krisztian will provide practical insights to help make informed decisions and ensure telemetry pipelines are both effective and resilient.
