Do you have experience working with logs? What tools did you use?

Yes, I have experience working with logs. I usually used tools like ELK Stack (Elasticsearch, Logstash, Kibana) for centralized log collection and analysis. I also used Fluentd and Graylog for log aggregation and filtering. In test automation, I often used built-in loggers, such as logging to files with Python's logging or Log4j in Java, to catch errors and analyze test behavior.
