Where and how did you look at the logs?

Logs are usually viewed depending on the type of application and infrastructure. In local development — in the IDE console or terminal where the application is run. In production — through centralized logging systems, such as ELK Stack (Elasticsearch, Logstash, Kibana), Graylog, or Splunk.

If it's a web application, I can look at server logs (for example, nginx, node.js) and application logs. For mobile applications — through tools like Android Studio Logcat or Xcode Console.

I also use filters and keyword searches, timestamp filtering, and log level filtering (ERROR, WARN, INFO) to quickly find the necessary information.
