What tools and services have you used for log viewing?

To view and analyze logs, I used the following tools and services:

• ELK Stack (Elasticsearch, Logstash, Kibana): a powerful stack for collecting, storing, and visualizing logs.
• Splunk: an enterprise solution for log monitoring and analysis.
• Graylog: a centralized logging platform with a user-friendly interface.
• Grafana + Loki: for visualization and searching logs.
• tail, grep, less: basic command-line utilities for viewing logs on servers.
• Cloud services: such as AWS CloudWatch Logs, Google Cloud Logging for cloud applications.

Each of these tools helps efficiently search for errors, analyze system behavior, and monitor its state.
