This presentation gives an overview of the Apache SkyWalking project. It explains Apache SkyWalking in terms of it's architecture, protocols, users and languages supported.

1. What Is Apache SkyWalking ?
● A performance monitoring tool for distributed systems
● An open source observability platform
● Apache 2.0 license
● Collect, analyse, aggregate and visualize data
● Provides auto instrument agents for services
● Maintain a clear view of your distributed systems
● For cloud native, micro service and
● Container-based (Docker, K8s, Mesos) systems

2. SkyWalking Architecture

3. SkyWalking Architecture
● The architecture has four parts
● (1) Probes
– Collect data and reformat it
– For SkyWalking requirements
– Different probes support different sources

4. SkyWalking Architecture
● (2) Platform back end
– Supports data aggregation, analysis
– Drives process flow from probes to the UI
– Analysis includes
● SkyWalking natives traces and metrics, 3rd party,
● Including Istio and Envoy telemetry, Zipkin trace format
– Can customize aggregation and analysis
– Using Observability Analysis Language for
● Native metrics
● Meter System for extension metrics

5. SkyWalking Architecture
● (3) Storage
– Houses SkyWalking data
– Through an open/pluggable interface
– Choose an existing implementation such as
● ElasticSearch, H2,
● MySQL cluster managed by Sharding-Sphere
– Implement your own

6. SkyWalking Architecture
● (4) User Interface (UI)
– Highly customizable
– Web based interface
– End users can
● Visualize data
● Manage data

7. SkyWalking Users

8. SkyWalking Probe Protocols
● Probe protocols, how agents send/receive
– Collected metrics data and traces
– The formats of each entity
● Cross Process Propagation Headers Protocol (and )
● Cross Process Correlation Headers Protocol
– Are in wire data format
– Agent/SDK usually uses HTTP/MQ/HTTP2 headers
– To carry the data with RPC request
– Remote agent will receive this in a request handler
– And bind the context with this specific request

9. SkyWalking Probe Protocols
● Trace Data Protocol
– Is out of wire data
– Agent/SDK uses this to send traces
– And metrics to Skywalking
– Or other compatible backend

10. SkyWalking Query Protocol
● The backend provides query capability
● To SkyWalking UI and others
● Query capabilities depends on analysis metrics
● These queries are based on GraphQL
– A query language for the API
– A server-side runtime for executing queries
– By using a type system you define for your data
– Isn't tied to any specific database
– Or storage engine
– Backed by your existing code and data

11. SkyWalking Language Agents
● Micro service meshes supported
– Istio
– Envoy
● Multiple language agents supported
– Java
– .Net Core
– PHP
– NodeJS
– Golang
– LUA agents
