What is Observability?

• Observability is typically divided into three key phases:

  1. Detection: Identifying what went wrong and where
  2. Investigation: Understanding why something went wrong
  3. Remediation: Recovering from the issue and restoring a healthy state

• The three major pillars of observability are:

  1. Metrics: Measuring performance characteristics and system components
  2. Logs: Diving into individual event streams from applications and infrastructure
  3. Traces: Understanding the relationships between components and identifying potential issues

Observability Challenges Faced by Customers

1. Monitoring Coverage: Ability to monitor all components of the application stack, including different languages, databases, and compute platforms.

   • CloudWatch Database Insights provides a unified view and insights for Amazon Aurora databases.

2. Correlating Data: Difficulty in navigating and correlating metrics, logs, and traces across related resources.

   • CloudWatch Unified Navigation provides an automatic relationship reveal and inline key telemetry views.

3. Data Silos: Fragmentation of application data across different data stores, making it hard to get a unified view.

   • Integration of OpenSearch and CloudWatch Logs enables enhanced query capabilities and unified analytics.

4. Distributed Tracing: Identifying which components are causing issues in distributed systems.

   • CloudWatch Span Analytics provides visibility and analytical capabilities for application transactions.

5. On-Call Investigations: Stress and lack of context when being paged during on-call incidents.

   • Amazon Q Developer Ops Assistant provides hypotheses, observations, and guided investigations to aid on-call engineers.
