Observability in the world of microservices

  1. 1. Observability in the world of Microservices Chandresh Pancholi
  2. 2. About me ● Working as Software engineer and leading India office for One Concern ● Worked with Flipkart & Arvind group ● Apache committer for project Apache gossip ● Speaker at Meetups & Conferences Coordinates: Email: chandresh@oneconcern.com Linkedin: https://www.linkedin.com/in/chandresh-pancholi-467a8015/

  4. 4. Monolith vs Microservice
  5. 5. Observability “Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs”.
  6. 6. Pillars of Observability 1. Monitoring 2. Logging 3. Tracing
  7. 7. Monitoring 1. Prometheus 2. Graphite 3. InfluxDB
  8. 8. Logging 1. FluentD 2. FluentBit 3. Logstash
  9. 9. Tracing ● Jaeger ● Zipkin ● Kiali
  10. 10. Jaeger Architecture
  11. 11. Jaeger benefits ● Distributed transaction monitoring ● Performance & latency optimisation ● Root cause analysis ● Service dependency analysis ● Distributed context propagation
  12. 12. Jaeger features ● Uses consistent upfront sampling with individual per service/endpoint probabilities ● Multiple storage backends: Cassandra, Elasticsearch, memory. ● Adaptive sampling ● Post-collection data processing pipeline ● Libraries available in Java, GO, Node, Python, C++
  13. 13. Terminology ● Span ⇒ A span represents a logical unit of work in Jaeger that has an operation name, the start time of the operation, and the duration. Spans may be nested and ordered to model causal relationships. ● Trace ⇒ A trace is a data/execution path through the system, and can be thought of as a directed acyclic graph of spans.
