OS Management

The OpenSearch Index Management feature in Amorphic provides a comprehensive toolset for managing and monitoring OpenSearch clusters. It offers detailed insights into cluster state, health, and configuration, enabling users to perform administrative tasks and ensure optimal performance.

  • Users can view critical cluster details including name, state, health, endpoints, version, and creation date
  • The interface displays advanced configuration details such as instance type, instance count, EBS options, VPC settings, encryption at rest, and domain endpoint configurations
  • Users can monitor availability zone information, including the number of available data nodes and total shards per zone
  • Users can repair catalog metadata stored in the OS Cluster and can also get details about the actions performed on the index
