Kibana's Time Series Visual Builder, initially an experimental feature, is set to officially debut in version 6.0, bringing enhanced tools for time series data analysis and visualization. While Kibana traditionally struggled with time series analysis, the Visual Builder offers a comprehensive solution with various visualization types, including Time Series, Metric, Top N, Gauge, and Markdown. Users can customize data and display settings, apply different aggregation types, and utilize advanced calculations like derivatives or moving averages. This new tool positions Kibana more competitively against Grafana, especially in the context of time series visualization, though Kibana remains primarily integrated with Elasticsearch, whereas Grafana supports multiple data stores. The article also touches on the potential impact of the Visual Builder on the future of Timelion, another time series tool within Kibana.
