Mastering Distributed Tracing

Components of a data mining pipeline

There are probably many ways of building near real-time data mining for traces. In Canopy, the feature extraction functionality is built directly into the tracing backend, whereas in Jaeger, it can be done via post-processing add-ons, as we will do in this chapter's code exercise. Major components that are required are shown in Figure 12.1:

• Tracing backend, or tracing infrastructure in general, collects tracing data from the microservices of the distributed application
• Trace completion trigger makes a judgement call that all spans of the trace have been received and it is ready for processing
• Feature extractor performs the actual calculations on each trace
• An optional Aggregator combines features from individual ...
