%description
    Jaeger is an OpenTracing-compatible distributed tracing system,
    used for monitoring microservice-based architectures. It provides:
    distributed context propagation, distributed transaction
    monitoring, root cause analysis, service dependency analysis,
    and performance/latency optimization. It stores the data in
    ElasticSearch. Jaeger has three components: an agent service local
    to the application (jaeger-agent), a central collector service for
    storing information (jaeger-collector) and a central query service
    for retrieving information (jaeger-query).
