This about how many api calls your applications were doing 3-4 years ago, and think about how many integration and difference services your requests is crossing before to come back to the final destination. How do you know this step of your pipeline is taking too much time? What is taking 2 seconds to answer? Is it the authentication service? Maybe it's the invoice generation service or the notification platform. Open Tracing is a distributed tracing cross vendor and open source that help you to understand bottleneck and to profile the requests from where they arrive at the final user. In an ecosystem where microservices and as a service concept are growing this can be a real challenge. During this presentation, we will see how it works from a general point of view to land in some real implementation, examples, and demo.

Typical problems with logs
¨ Which library do I need to use?
¨ Every library has a different format
¨ Every languages exposes a different format

Tracing is not something new
¨ There are vendors
¨ Every vendor has their own format

Every ten years, history repeats itself but now
¨ Microservices
¨ Polyglot architecture
¨ A different distribution

concurrent systems?

Child Span
¨ Spans - Basic unit of timing and causality. Can be tagged with
key/value pairs.
¨ Logs - Structured data recorded on a span.
¨ Span Context - serializable format for linking spans across network
boundaries. Carries baggage, such as a request and client IDs.
¨ Tracers - Anything that plugs into the OpenTracing API to record
information.
¨ ZipKin, Jaeger, LightStep, others
¨ Also metrics (Prometheus) and logging

Implement a comfortable
solution to store and quickly manipulate
all your traces.

14. Cardinality everywhere!
Monitoring, events, traces… All time series, but they are different!

There are different information that you can get from traces. In real time
and not.
Providing a good way to store data without the ability to visualize them
is not the point.
Visualisation

PS I don’t know if it’s using OpenTracing (probably not) but it’s a nice visualisation.

Thanks OpenTracing for the support.
