Kibana pie chart visualizations provide three options for this metric: count, sum, and unique count aggregations (discussed above). previous step. In addition to time series visualizations, Visual Builder supports other visualization types such as Metric, Top N, Gauge, and Markdown, which automatically convert our data into their respective visualization formats. seamlessly, without losing any data. Now we can save our area chart visualization of the CPU usage by an individual process to the dashboard. To check if your data is in Elasticsearch we need to query the indices.
