Micro-service system is a distributed deployment architecture. Different service modules are deployed on different servers. When problems arise, most situations need to locate specific servers and service modules according to the key information exposed by the problems. Centralized logging helps organizations tap into server logs efficiently. A centralized logging architecture adds a degree of automation to the process by aggregating all the logs from the different data sources in a central data store, applying parsing and processing so the logs are easier to read and analyze, and providing analysis and visualization tools. Logging monitor is the visualization tool through which you can analyze logs efficiently.
