Eric Schabell, Director of Community and Developer at Chronosphere and a CNCF Ambassador, shares his insights on enhancing observability in cloud-native systems. He dives into how Prometheus, while popular, struggles with large data volumes and cost optimization. Schabell discusses the challenges of scaling observability, balancing self-hosted versus managed solutions, and the importance of managing metrics effectively. Listeners will also learn about the critical role of efficient data collection and visualization in supporting agile monitoring and issue resolution.

Episode notes
Prometheus: A Metrics Collection Tool
- Prometheus is a metrics collection tool designed for cloud-native environments.
- It's a key signal within broader observability platforms.
Prometheus's Data Collection
- Prometheus scrapes data from endpoints, minimizing intrusion.
- It uses a pull-based model, avoiding collectors and agents, and offering auto-instrumentation.
Observability Signal Types
- Metrics, logs, and traces are distinct signal types in observability.
- Metrics track resource consumption, network lag, logs record events, and traces map service calls.
