Monitoring alarm

The number of microservice instances is large, and abnormal events occur frequently, which easily lead to false positives, alarm fatigue, and neglect of real faults.

Performance

The coupling between microservice instances is loose, the performance jitter correlation is low, and the performance problem is difficult to reproduce; The performance problems caused by multiple microservices are more difficult to reproduce.

Debug

The dynamic interaction between microservice instances makes it very difficult to reproduce and locate bugs.

Perception

The interaction between a large number of microservice instances is frequent, and the abstraction level of data collection is low, which greatly increases the difficulty for engineers to understand the operation mechanism of the application.
