Best Practices and Advanced Techniques
There are various best practices for getting the most from the ELK stack:
- Use log forwarding agents like Filebeat for log shipping. This decouples data pipelines. 
- Enable TLS for encrypting connections between components. Restrict network access where possible. 
- Use indexes wisely to segregate logs rather than sending all logs to one index. 
- Monitor cluster health, shard volumes, JVM heap, and other metrics. 
- For high availability, have multi-node Elasticsearch clusters with replication. 
- Use Curator to optimize, back up, and delete old log indices. 
- Ingest metrics into Elasticsearch for combined log analytics and monitoring. Visualize metrics time-series with Kibana. 
- Build integrations with CI/CD pipelines, application monitoring, and ITSM tools using the ELK APIs.
