SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Observability data can be expensive at scale. Smart sampling strategies maintain visibility while controlling costs.

Core Features & Use Cases

  • Head-Based Sampling: Decision at trace start with probabilistic sampling or rate-limiting.
  • Tail-Based Sampling: Decisions after trace completes for errors, latency, or attributes.
  • Hybrid Approaches: Combine strategies to balance cost and visibility.
  • Log Sampling Strategies: Dynamic log levels, sampling, and pre-export aggregation.
  • Cost Optimization Tips: Retention, aggregation, tuning, tiered storage.

Quick Start

Use this approach to configure traces to sample a representative subset of requests while filtering verbose logs and aggregating similar events before export.

FAQPage Schema
How do I reduce observability costs for high-volume distributed tracing?▼

Reduce observability costs by implementing smart log and trace sampling. You can apply head-based or tail-based strategies to maintain visibility while controlling expenses in high-volume environments.

What is the difference between head-based and tail-based trace sampling?▼

Head-based trace sampling makes decisions at trace start using probabilistic rates, while tail-based sampling decides after completion based on errors or latency. Hybrid approaches combine both to balance cost and visibility.

How do I configure OpenTelemetry sampling rates for errors and high latency?▼

Configure OpenTelemetry sampling by setting configurable rates and applying tail-based rules. This captures traces based on specific error conditions and latency thresholds after the trace completes.

What is the best way to sample logs before they reach centralized pipelines?▼

Sample logs before export using dynamic log levels and pre-export aggregation. This filters verbose logs and aggregates similar events, reducing data volume in centralized log pipelines.

Can I use hybrid sampling strategies to optimize both traces and logs?▼

Hybrid sampling strategies combine head-based and tail-based approaches for traces alongside dynamic log sampling. This balances cost and visibility across both distributed tracing and centralized logging.

What are cost-aware retention and aggregation strategies for observability data?▼

Cost-aware retention and aggregation strategies involve tiered storage, data tuning, and pre-export aggregation. These approaches reduce long-term observability expenses while keeping necessary data accessible.
