preface
** The term “link tracking” was coined in 2010 when Google published a Dapper paper that explained how Google’s own distributed link tracking was implemented and how it was made transparent to applications at a low cost.
In fact, Dapper was just an independent call link tracking system at the beginning, and gradually evolved into a monitoring platform, based on which many tools were bred, such as real-time warning, overload protection, index data query, etc.
In addition to Google’s Dapper, there are some other well-known products, such as EagleEye of Ali, CAT of Dianping, Zipkin of Twitter, Naver (parent company of LINE) Pinpoint and Skywalking, a domestic open-source software.
Introduction to the
Zipkin is an open source call chain analysis tool for Twitter. Currently, it is widely used based on SpringCloud SleUTH. It is characterized by lightweight and easy to use and deploy.
Pinpoint is the Korean open source based bytecode injection call chain analysis, as well as application monitoring analysis tools. Feature is to support a variety of plug-ins, UI powerful, access end without code intrusion.
SkyWalking is a native open source bytecode injection based call chain analysis and application monitoring analysis tool. Feature is to support a variety of plug-ins, strong UI function, access end without code intrusion. You have joined the Apache incubator.
CAT is a series of monitoring platform tools such as call chain analysis, application monitoring analysis, log collection, monitoring and alarm based on code and configuration.
