What tools or methods do you use for analyzing and viewing logs in your projects?

Tools and methods commonly used for analyzing and viewing logs in projects include:

• Log files: viewing through text editors (e.g., VSCode, Notepad++) or command-line utilities (tail, less, grep).
• Log aggregators and monitoring systems: such as ELK Stack (Elasticsearch, Logstash, Kibana), Graylog, Splunk — allow centralized collection, indexing, and analysis of logs.
• IDEs and plugins: built-in log viewing tools or plugins for convenient analysis.
• Filtering and searching: using regular expressions and filters to quickly find needed entries.
• Automation: scripts for parsing logs and generating reports.

Example of a command to view the last 100 lines of a log file with error filtering:

tail -n 100 application.log | grep ERROR
