Through what tools did you look at logs?

Various tools are used to view logs depending on the environment and requirements:

• Command line: tail, less, grep — for quick viewing and filtering logs on the server.
• System utilities: journalctl for systems with systemd.
• Log aggregators and platforms:
  • ELK Stack (Elasticsearch, Logstash, Kibana) — for collecting, storing, and visualizing logs.
  • Grafana Loki — for indexing and searching logs.
  • Splunk — a commercial solution for log analysis.
  • Graylog — a platform for centralized logging.
• Cloud services: AWS CloudWatch, Google Cloud Logging, Azure Monitor.

The choice of tool depends on the volume of logs, search requirements, visualization, and integration with other systems.
