Elastic Stack 6.0.0-beta1 released

By Tyler Hannan

6.0.0-beta1 is available today!

Before you get too excited, keep in mind that this is still a beta so don’t put it into production. There is no guarantee that any of the 6.0.0-beta versions will be compatible with other pre-releases, or the 6.0.0 GA. We strongly recommend that you keep this far, far away from production. And, since it is an beta, it is not available on Elastic Cloud.

During the 5.0 release, we introduced the Elastic Pioneer Program and are continuing the same program with the 6.0 preview releases.

Elasticsearch

For more detailed information, and many other features, peruse the Elasticsearch detail post.

  • Disk space matters. Running out of disk space can ruin your night sleep. We’ve done more work (settings, log configuration defaults) to minimize the effect.
  • changeme as a default password is no more. The bootstrap.password setting and setup-passwords command line tool are now here.
  • ‘You know, for search’. A light shard prefiltering phase if targeting at least 128 shards, rewriting queries at the shard level, max_concurrent_shard_requests…You know, for scalable search.

Kibana

‘Visualize’ all the features, and ‘Discover’ more information in the detail post.

  • With 6.0.0 rapidly approach, we built an upgrade assistant that identifies breaking changes, allows enabling deprecation logging, and provides a one-click migration.
  • You <3 alerting. We <3 alerting. You will <3^2 alerting with a UI for creating alerts based on thresholds. Averages bytes by host? Click, type, done.
  • Visualizing your data is difficult when you can’t see the results. In 6.0 we are working, hard, on improving accessibility. This effort begins with a full restyle of Kibana to provide proper contrast for those with different forms of color blindness.
  • Full screen mode available for your NOC’s, SOC’s and monitors around the office. Pair this feature with the dashboard only mode for a true view-only experience

Logstash

For more information, grok the detail post.

  • Have a complex pipeline? We have a pipeline visualization UI now! Easily track performance issues with plugins and understand your overall dataflow using our new monitoring enhancement!
  • So you got started with the ingest node and created ingest pipelines…So you now want to move this to Logstash to use complex conditionals, multiple inputs and outputs. We’ve got you covered – there’s now a migration tool to do just that!
  • With centralized configuration management feature, you can now create and manage your configuration all within Kibana! Logstash instances can instantly apply configuration changes without you having to restart or log in to any machines! Talk about self-service Logstash management!

Beats

We don’t ‘let the beat drop’ but we drop the updates in a detail post.

  • Say Heya to Auditbeat! Auditbeat is our newest Beat, that can read, parse, correlate, and ship data collected from the Linux Kernel audit framework. Think of it like an alternative for auditd, but one that integrates perfectly with the Elastic stack. On top of that, Auditbeat has a file integrity module, for detecting changes to files and directories.
  • We have simplified how you enable, disable, and test Metricbeat and Filebeat modules, by introducing subcommands.
  • Retrieving Docker logs and enhancing them with Docker metadata was never this simple. Filebeat gets native support for extracting the container ID from logs and using it to query the Docker API for the metadata.

ES-Hadoop

We’ve reduced the details to some bullets, but the original map is in the detail post.

  • Support for Spark 2.2.0 and Structured Streaming are here without impacting existing Spark integrations.
  • ES-Hadoop can read/write data with the new “join” field type.
  • Nested Java Bean serialization problems, field exclusion problems on Pig and SparkSQL, partial document reads and serialization exceptions, all fixed in this release
