Java Application Monitoring and Diagnosis Solution

In this use case, the ARMS-based application monitoring solution is adopted to resolve pain points in monitoring distributed Java applications.

Business pain points

Rapid growth of Internet businesses has brought about increasing traffic pressure, and business logic has also become more complicated. In this context, traditional single-machine applications can no longer satisfy customer needs. More and more websites have adopted distributed deployment architecture. Moreover, basic development frameworks, such as Spring Cloud and Dubbo, have gradually matured. Now, more enterprises vertically split their website architectures by business module and adopt a microservice architecture (MSA), which is more suitable for collaborative development among teams and quick iterations.

The distributed MSA is advanced in terms of development efficiency. However, it brings about huge challenges for traditional monitoring, operation and maintenance, and diagnosis technologies. For example, we confronted the following challenges when applying the distributed MSA to

  • Difficulty in identifying the problem: The customer service center submits customer feedback about problems with buying items to technical support engineers for troubleshooting. A website request in the distributed MSA always passes through multiple services and nodes before a result is returned. Once an error occurs, the engineers usually have to go through the logs over and over to identify possible problems. Multiple teams are involved in solving simple problems.

  • Difficulty in identifying the bottleneck: In case a website freezes, identifying the bottleneck quickly is difficult. It may be a fault in the network between the user terminal and the server, a result of server overload, or high database pressure. Even when the cause is identified, it is still difficult to quickly identify the error in the code.

  • Difficulty in organizing the architecture: The business logic has become more complicated. It is difficult to organize the code that specifies the depending downstream services of an application, which may be the database, HTTP API, or cache, and to organize the code that specifies the external calls depending on this application. It is more difficult to organize the business logic, manage the architecture, and plan the capacity. For example, during preparations for "Double 11" promotion campaigns, it is hard to predict the number of servers required for each application.

ARMS-based application monitoring solution

The application monitoring function provided by ARMS originates from the Alibaba EagleEye distributed tracing and monitoring system. It resolves the preceding problems without requiring you to modify the existing code.

  • Call topology: You can view the call topology of an application on ARMS, for example, services that depend on the application and downstream services that the application depends on. As shown in the figure, you can find that the applications monitored by ARMS depend on Redis, MySQL databases, and some external HTTP services. The dependency on the MySQL database is the bottleneck, with an average time consumption of over 1700 ms.

  • Slow services and SQL reports: This application's SQL analysis reports clearly display slow SQL statements and slow services.

  • Distributed call link queries: Click the interface snapshot of a slow SQL statement to retrieve a request that includes the SQL call, view the call stack of the method, and then identify problems in the code.

Whether from a global perspective or from the perspective of a single call, ARMS comprehensively resolves your pain points in the distributed Java application monitoring field. ARMS supports browser monitoring and business monitoring as well as application monitoring to provide comprehensive protection for your sites, from key business metrics and customer experience to application performance.

User Experience Monitoring

User experience business pain points

When a user accesses a service, the whole access process can be classified into three phases: page production (server status), page loading, and page running. To ensure stable running of online services, the running statuses of services are monitored on the server. The existing monitoring system on the server has matured, but status monitoring for page loading and page running has been falling short. This is because less emphasis is put on front-end monitoring, as the monitoring on the server can partially replace the front-end monitoring. In this case, the system access details cannot be perceived when the system is running online and a user accesses the system. Therefore, it is difficult to locate a front-end problem that online users occasionally encounter.

Business pain points

  • Difficulty in identifying the performance bottleneck: When a user gives feedback on slow page loading, it is difficult to quickly find out the bottleneck. It may be a fault in network connection, resource loading, or page DOM parsing problem. Is it associated with the province and country where the user is located, or the browser and equipment used by the user? These problems cannot be reproduced quickly for cause identification.

  • Inability to view error reports during user access: After a system is put into operation, it cannot be used normally due to a large number of JavaScript errors generated during user access. If the error details for user access cannot be acquired in time, are a large number of users lost? If a user gives feedback on page usage details, can the use case be reproduced immediately? Or can the error details be acquired for quick restoration? All these problems are the difficulties currently encountered by developers.

  • Unknown asynchronous API calling details: All the HTTP status codes returned by API calls are 200, but this does not mean that the API is completely normal. If the business logic is abnormal, can it be perceived in time? If all the HTTP status codes returned by API calls are normal, but the whole process consumes a long time, how can the global conditions be grasped and optimized? Under these unknown situations, problems cannot be discovered in time, and the customer experience cannot be improved.

ARMS-based front-end monitoring solution

The front-end monitoring function is achieved based on the massive real-time log analysis and processing services provided by ARMS. The function is used to monitor the access conditions of all real online users and resolve the preceding problems.

  • Finding exceptions in the application overview: You can view the overall information on the application using the front-end monitoring function, including application satisfaction, JavaScript error rate, access speed, API request success rate, and PV details. In the following example, the average value of the JavaScript error rate is 3.78%, which has increased by 56.25% compared to the same period of the last week.

  • Performance data trend and waterfall chart: On the Access Speed page, you can view detailed metrics related to the page performance and the page loading waterfall chart. Then, you can locate the performance bottleneck based on the detailed data.

  • View page stability based on JavaScript error rates and error clustering: On the JavaScript Stability page, you can view a ranking of error rates from high to low and a ranking of error clusters. That is, you can intuitively see which pages have higher JavaScript error rates and which errors are most common.

  • Analysis on API access based on API requests: On the API Request page, you can view data on API success rates and time consumption, and fully grasp interface conditions.

  • Access details: Click Details and go to the Access Details page. There, you can view the access details. For example, you can identify an error according to the error information, including File, Stack, Line, and Col.
