Have you used a centralized log collection system in your projects?

Yes, in projects I often used a centralized log collection system for convenient monitoring and analysis of application performance. This is usually implemented using tools such as ELK Stack (Elasticsearch, Logstash, Kibana), Graylog, or Splunk.

Centralized log collection allows:

• Collecting logs from different services and servers in one place.
• Quickly searching and filtering events by time, level, components.
• Setting up alerts for errors or anomalies.

In Java projects, loggers with support for appenders, such as Logback or Log4j, are often used to send logs to the centralized system, which can send logs over the network or to files, then collected by agents.
