Overview


Welcome to Gemini Central V3.0 the new name for Gemini Enterprise Manage!

This software-based product greatly simplifies the installation and administration of complex technology platforms such as Splunk, Tableau, and MinIO.

Recent iterations of Gemini software have demonstrated the advantages of having a Gemini Management Center node at its core that can manage and upgrade an entire Splunk environment, or even multiple Splunk environments.

New features, such as the central collation of Splunk diags and a central backup solution for all Splunk/Gemini config files have been very popular with our customers.

New in Version 3.0

Recommended Actions

In Gemini Central V3.0, we are introducing a new feature called, Recommended Actions advising on any outstanding issues that need to be addressed on a Gemini instance.

Use the Gemini Management Center node to select a ‘Recommended Action’ on any instance and address the issue immediately in a separate browser tab.


AWS Provisioning

Another exciting new feature, AWS Provisioning, enables central provisioning of complete Splunk Indexer and Search Head clusters based on AWS EC2 instances using Splunk AMI’s, direct from a Gemini Central node acting as the Management Center.

This is an alternative to the use of our hardened OS built-in to our own Gemini AMI, but if chosen, will enable customers to get up and running themselves with complex Splunk environments on AWS in just a few minutes, provided they have their AWS secret keys and passwords available.

A Gemini Agent will be installed to each Splunk instance during the install, allowing the Management Center node central observation and a fast Splunk upgrade facility.

For more detail on all of these features, including resource requirements and installation instructions, please refer to our Gemini Central - Administration Guide V3.0
