Log aggregation is an Observability pattern in microservice. In the case of a distributed transaction in a microservices architecture, every service instance will generate a log file in a standard format. Unless the logs are centralized, it becomes difficult to understand the application behavior from the logs.
Log aggregation pattern solves this issue. A centralized logging service aggregates logs from every service instance. In the case of Elastic Stack, the logs are indexed as well. Users will be able to search and analyze the logs. Alerts can be triggered whenever certain messages appear in the logs.
Fluentd is a logging agent which can aggregate logs.
In the case of Amazon web services, AWS Cloud Watch does the same.
