Learn how to use Logstash to safely route a subset of production data to pre-production clusters by using efficient sampling techniques and by leveraging the UDP protocol’s fire-and-forget functionality.

It can be difficult to use synonyms to define all possible variations of a word. Fortunately, you can easily combine stemmers and multi-word synonyms to take the quality of your search results to the next level.

So you've started structuring data with grok and building custom grok patterns. But what happens if you just can’t get your grok patterns to work? Learn how to debug a broken grok pattern using Kibana’s Grok Debugger.

Structuring your Elasticsearch data with grok on ingest can help you take your observability use cases to the next level. Learn how to incrementally create a new grok pattern from scratch to boost search speeds.

Elasticsearch isn't just for full-text search, it's also a powerful analytics engine. Learn how to structure your metrics data on ingest to make sure your analytics run in near-real-time.

Learn how to use an ingest node to add an ingest timestamp to documents and to calculate ingest lag. This data can then be used to detect unexpected slowdowns in the ingest process or to detect incorrectly set timestamps on monitored systems.

Every search use case is a little different, but Elasticsearch is flexible enough to work for all of them. In this blog, we'll take a look at mixing and matching queries to tune relevance according to your specific needs.

Lookup enrichment can make your logs and metrics even more valuable for observability. In this tutorial, we'll take a look at using data stored in a CSV file to enrich data with ingest node.
