Provisioning an Elasticsearch cluster in Qbox is easy. In this article, we walk you through the initial steps and show you how simple it is to start and configure your cluster.

Logstash is a layer in the Elasticsearch ELK stack that allows you to parse and process logs from many sources in your infrastructure and store them in a centralized location. It began as an independently developed, open source project, but now exists as a part of the official Elasticsearch family of products, bolstering development and support and retaining its Apache license. For a brief introduction to Logstash, take a look at our “Welcome to the ELK Stack” post and the official getting started guide. If you’re looking for a more in-depth overview, check out the Logstash book.

Many facets have a directly equivalent aggregation, and migration is as straightforward as replacing the keyword “facets” with “aggregations” or “aggs” in your query. For facets that do not have an equivalent aggregation, the Elasticsearch reference provides us with basic examples for migrating these facets to their aggregation counterparts. Two of these, query facets and facet filters, will be referenced in this post.
