Daniel Berman's article examines the differences between Grafana and Kibana, two popular data visualization tools often used in conjunction with the ELK Stack for analyzing time-series data. While both tools offer similar functionalities regarding data handling, they differ significantly in display configuration options, with Grafana providing richer visual features and more customization in data representation. The article provides a step-by-step guide on installing Grafana, integrating it with Elasticsearch, and setting up a Grafana dashboard using Ubuntu/Debian. Berman highlights Grafana's user-friendly interface and ease of setup as major advantages, despite some compatibility issues with Elasticsearch 5.x, particularly concerning the alerting feature. He suggests that while Kibana users might not find a compelling reason to switch, Grafana's enhanced usability makes it worth exploring.
