# Observability Concepts

> Explore the core concepts behind observability at Honeycomb.

To fully grasp observability, start with these concepts.

<Card title="Events, Metrics, Logs" href="/get-started/basics/observability/concepts/events-metrics-logs/">
  Explore a side-by-side-by-side comparison of instrumenting via different data types.
</Card>

<Card title="Distributed Tracing" href="/get-started/basics/observability/concepts/distributed-tracing/">
  Learn about distributed tracing, which helps tie together instrumentation from separate services, so you can understand complex processes.
</Card>

<Card title="Services" href="/get-started/basics/observability/concepts/services/">
  Learn about services, and how they are created and managed in Honeycomb.
</Card>

<Card title="High Cardinality" href="/get-started/basics/observability/concepts/high-cardinality/">
  Learn what high cardinality and high dimensionality are, and understand what makes high cardinality data important.
</Card>

<Card title="Core Analysis Loop" href="/get-started/basics/observability/concepts/core-analysis-loop/">
  Learn about the core analysis loop, which is the process of using your telemetry to form hypotheses and to validate or invalidate them with data. In observability, it is the basis of debugging from first principles.
</Card>

<Card title="Instrumentation" href="/get-started/basics/observability/concepts/instrumentation/">
  Understand what instrumentation is. Explore best practices and conceptual patterns for instrumenting applications.
</Card>

<Card title="eBPF" href="/get-started/basics/observability/concepts/ebpf/">
  Learn about eBPF and why it is important to observability.
