Tools

Get Cluster Health

Returns the health status of your Elasticsearch cluster. Use this to check if the cluster is operational (green/yellow/red status), monitor shard allocation, and identify potential issues. Useful for monitoring and troubleshooting.

Get Cluster Stats

Returns high-level cluster statistics including node count, shard distribution, index count, document count, storage usage, and more. Use this for capacity planning and monitoring cluster growth.

Get Cluster Settings

Retrieves current cluster-wide settings including persistent and transient settings. Use this to view configuration like shard allocation, routing, discovery settings, and custom cluster properties.

Update Cluster Settings

Updates cluster-wide settings dynamically without requiring a restart. Can set persistent (survives restart) or transient (reset on restart) settings. Use for tuning shard allocation, routing, and other cluster behaviors.

Get Cluster State

Returns comprehensive information about the cluster state including metadata, routing table, nodes, and cluster settings. Warning: can return large responses. Use metrics parameter to filter specific sections.

Get Nodes Info

Returns information about cluster nodes including OS, JVM, thread pools, plugins, and configuration. Useful for understanding cluster topology and node capabilities.

List Indices

Lists all indices in the cluster with key information like health, status, document count, size, and shard count. Use this to discover available indices and monitor their health.

Create Index

Creates a new index with optional settings, mappings, and aliases. Use this to set up new indices with custom shard configuration, analyzers, and field mappings before indexing data.

Delete Index

Permanently deletes an index and all its data. This operation cannot be undone. Use with caution. Supports wildcards to delete multiple indices.

Get Index

Retrieves detailed information about one or more indices including settings, mappings, and aliases. Use this to understand index configuration and structure.
