- 14. Jaeger benefits ● Distributedtransaction monitoring ● Performance & latency optimisation ● Root cause analysis ● Service dependency analysis ● Distributed context propagation
- 15. Jaeger features ● Usesconsistent 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++
- 16. 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.
