How to analyze the function and architecture of pinpoint? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Overview introduction to pinpoint

What is pinpoint: pinpoint is a platform for analyzing large-scale distributed systems, providing solutions to deal with massive tracking data, mainly for tomcat-based Java applications.

* * Why do you use it: * compared with today, the number of Internet users in the past is relatively small, and the architecture of Internet services is not so complex. Web services typically use a two-tier (web server and database) or three-tier (web server, application server and database) architecture. Nowadays, however, with the growth of the Internet, a large number of concurrent connections need to be supported, and functions and services need to be combined organically, resulting in more complex software stack combinations. More specifically, n-tier architectures with more than three tiers have become more common. As a result, the complexity of the system increases. The more complex the system, the more difficult it is to solve problems, such as system failure or performance problems. It is not too difficult to find a solution in a three-tier architecture, only three components such as web server, application server and database need to be analyzed, and the number of servers is small. However, if the problem occurs in an n-tier architecture, you need to investigate a large number of components and servers. Another problem is that it is difficult to see the big picture just by analyzing a single component; when a low-visibility problem occurs, the higher the complexity of the system, the longer it takes to find the cause. Worst of all, in some cases we may not even be able to find it. In order to solve the topology analysis and performance analysis under complex architecture, pinpoint arises at the historic moment.

Features, benefits and architecture

Function

Distributed transaction tracking, tracking messages across distributed applications

Automatically detect the application topology to help you figure out the architecture of the application

Scale horizontally to support large server clusters

Provide code-level visibility to easily locate failure points and bottlenecks

Use bytecode enhancement technology to add new features without modifying the code

advantage

Non-invasive: the deployment of agent can be completed without modifying the code of the application.

Resource consumption: the overall resource consumption has only increased by about 3%.

Architecture

HBase (for storing data)

Pinpoint Collector (collector of information, deployed in tomcat)

Pinpoint Web (provides WEB_UI interface, deployed in tomcat)

Pinpoint Agent (attached to the java application for sampling)
