Usage & Trade-offs
All fields support markdown. Use concise bullets and concrete situations.
When to use it
*
Deploy an Observability Stack when: - Running distributed or microservices applications. - Needing to debug issues in production environments. - Monitoring SLAs and alerting on anomalies. - Scaling systems where visibility is key to reliability.
Pros
*
- Holistic view of system state for faster MTTR. - Proactive alerting prevents outages. - Data-driven decisions for optimization. - Integrates with CI/CD for automated insights. - Scalable to handle high-volume telemetry.
Cons
*
- High setup and maintenance overhead. - Storage and compute costs for data retention. - Learning curve for query languages (e.g., PromQL). - Potential data overload without proper dashboards. - Security risks if logs expose sensitive info.
Notes
Note: Start with OpenTelemetry for standardized instrumentation. Define SLOs early to guide alerting thresholds. Regularly review and prune metrics to avoid noise.
