Description

Apache SkyWalking [1] is an application performance monitor (APM) tool for distributed systems, especially designed for microservices, cloud native and container-based (Docker, K8s, Mesos) architectures.

SkyWalking is based on agent to instrument (automatically) monitored services, for now, we have many agents for different languages, Python agent [2] is one of them, which supports automatic instrumentations.

The goal of this project is to extend the agent's features by supporting profiling [3] a function's invocation stack, help the users to analyze which method costs the most major time in a cross-services call.

To complete this task, you must be comfortable with Python, have some knowledge of tracing system, otherwise you'll have a hard time coming up to speed..
