![]() Whether the service has the problem of processing concurrency.Whether there is GC in the service, which can be excluded from the log and monitoring of the interruption time.Whether the master node is under pressure, CPU, memory and disk are stable, troubleshooting.Is there any service capability? Intervention investigation The number of requests has really increased. I just want to express that the low-frequency access of health examination will put pressure on the system. One of the development students said: without the health check, the service did not restart so many times. We carry out health inspection, and we come up with solutions. There are two computer rooms, one of which has more services than the other. There are problems in the production system, and everyone is discharging their own problems (I'm also drunk). If you use restart for troubleshooting, the time will be unpredictable and cannot be solved at one time) story production accident This article introduces the methods and tools used in our analysis and solution process, Among them, Arthas has become the last trump card (there is no online environment. Simply, some nodes have HTTP request timeout (occasionally), the service is not under pressure, and the thread pool is very idleįor problem 1, we closed the relevant after evaluation, which may lead to excessive middleware pressure, but it is difficult for problem 2.Some middleware e-mail implementation problems lead to excessive middleware pressure (insufficient resource evaluation), resulting in inspection failure. ![]() Some problems are encountered in the actual use process: ![]() backgroundĪt present, all Java applications use Spring Boot Actuator in Kubernetes as health check and readiness check. If it is solved, I hope the students of operation and maintenance can share it on the network to make up for the defects of this article. Without them, we can't complete the analysis.įinally, the problem has not been solved. ![]() First of all, we need to thank the colleagues who participated in the investigation together. ![]()
