The Elastic Stack — Elasticsearch, Kibana, Beats, and Logstash — powers a variety of use cases. And we have flexible plans to help you get the most out of your on-prem subscriptions.

Our resource-based pricing philosophy is simple — you only pay for the data you use, at any scale, for every use case.

Whether you are looking to manage a single cluster through its development phases or herd a fleet of deployments across multiple use cases in your organization, we have the provisioning, management, and orchestration tools to help you be successful. Simplify operations and increase your productivity with Elastic Cloud Enterprise and Elastic Cloud on Kubernetes — a suite of orchestration products from Elastic, the creators of Elasticsearch.

Things happen. Whether you have a hardware failure, a network failure, or something else you have to be ready. Here are some actions that you should be familiar with before things go bad.

• Restart a non-responsive Elasticsearch node
• Restore from a snapshot
• Retry a failed shard
• Relieve high heap pressure on one node

These resources discuss important operating system, Elasticsearch, and index lifecycle management configurations.

Elasticsearch is used for many use cases and each deployment can be tuned based on business requirements. Below you’ll find documentation for tuning search speed, indexing speed, Logstash performance, and Beats performance.

• Tune for search speed
• Tune for indexing speed

• Logstash performance tuning

• Filebeat troubleshooting

High heap can be caused by intensive monitoring, high cardinality in fielddata, mapping explosion, completion suggesters, too many shards, heavy search/indexing, etc. See below for information on monitoring and reducing heap use.

• Monitoring your deployment
