SkyWalking Rover
Setup
The first and most important thing is, that SkyWalking Rover startup behaviors are driven by configs/rover_configs.yaml. Understanding the setting file will help you to read this document.
Follow Deploy on Kubernetes document to run rover in your cluster.
Requirements and default settings
Before you start, you should know that the main purpose of quickstart is to help you obtain a basic configuration for previews/demos. Usually, the process to be monitored is first declared.
Then, you can use bin/startup.sh to start up the rover with their config.
SkyWalking OAP Compatibility
The SkyWalking Rover requires specialized protocols to communicate with SkyWalking OAP.
| SkyWalking Rover Version | SkyWalking OAP | Notice |
|---|---|---|
| 0.6.0+ | > = 10.0.0 | Only support Kubernetes. |
| 0.1.0+ | > = 9.1.0 |
Configuration
- Common configurations about logs, backend address, cert files, etc.
- Service Discovery includes advanced setups about the ways of discovering services on your Kubernetes cluster.
- Access logs reports L2 to L4 network traffic relative information through access logs, to help OAP backend to do topology and metrics analysis.
- Profiling is an on-demand feature to enhance general observability besides access logs. It provides eBPF powered process ON_CPU, OFF_CPU profiling and network advanced profiling to link HTTP traffic with SkyWalking and Zipkin traces.
- Pprof is a feature to collect self runtime profiling data.
To adjust the configurations, refer to Overriding Setting document for more details.
