Have you used Kibana for log analysis and visualization?

Yes, Kibana is widely used for log analysis and visualization, especially in conjunction with Elasticsearch and Logstash (the ELK stack). It allows creating dashboards, filtering, and searching logs in real-time, which helps quickly identify errors and anomalies in applications. For example, you can set up visualizations of error counts over time or distribution by error types, facilitating monitoring and diagnostics.
