This blog posts continues our overview of Elasticsearch metrics aggregation. We will focus here on such metrics aggregations as geo bounds, geo centroid, percentiles, percentile ranks, and some other single-value and multi-value aggregations. By the end of this series, you’ll have a good understanding of metrics aggregations in Elasticsearch including some important statistical measures and how to visualize them in Kibana. Let’s get started!

In the first part of our metrics aggregations series, we’ll discuss such single-value metrics aggregations as average and weighted average, min, max, and cardinality. The only multi-value aggregation type discussed in this article is extended stats aggregation. To help you understand how these aggregations work, we’ll accompany each description with the corresponding visualization in the Kibana dashboard. Let’s get started!
