X-Pack is an Elastic Stack extension that bundles security, alerting, monitoring, reporting, and graph capabilities into one easy-to-install package. X-Pack is a commercial product of Elastic that requires a license. By default, X-Pack is not installed as part of the DC/OS Elastic service. However, it’s easy to enable X-Pack as part of the service configuration:
You must set the update strategy to parallel when you toggle X-Pack in order to force a full cluster restart.
Afterwards, you should set the update strategy back to serial for future updates.
You can toggle this setting at any time. This gives you the option of launching an Elastic cluster without X-Pack and then later enabling it. Or, you can run a cluster with X-Pack enabled to try out the commercial features and, if at the end of the 30-day trial period you don’t wish to purchase a license, you can disable it without losing access to your data.
License Expiration
If you uninstall the X-Pack plugin via the service configuration or you let your license expire, remember these two important points:
- Your data is still there.
- All data operations (read and write) continue to work.
Graph, Machine Learning, Alerting and Notification, Monitoring, and Security all operate with reduced functionality when X-Pack becomes unavailable.
