Monitor & Manage Elasticsearch Cluster

Cluster Management & Monitor

Click the Manage panel to monitor and manage the Elasticsearch cluster, you can view the cluster health, indices, nodes, and shards information as below: In Cluster page, you can view the cluster health, nodes number, indices number, shards number, and other cluster overview information.

Nodes Management & Monitor

Click the Nodes tab to view the nodes list, you can see the list of nodes, click a node, you can view the node name, IP, disk information, memory usage and other useful node information.

Shards Management & Monitor

Click the Shards tab to view the shards list, you can view the shard name, index name, state, and other shards related information. Click any shard to open the Shard Detail Panel, which shows:

Metric	Description
Docs Count	Number of documents in the shard
Store Size	Storage size in bytes
Completion	Suggestion/index completion size
Fielddata	Field data memory usage
Query Cache	Query cache hit rate and size
Get/Search	Get and search operation metrics
Indexing	Indexing rate and latency (index, delete, update)
Merge	Segment merge statistics
Refresh/Flush	Refresh and flush operation metrics
Segments	Segment count, memory, and version map
Suggest	Suggestion operation metrics

This detail panel helps diagnose performance bottlenecks at the shard level.

Alias Management

From the Indices view, manage aliases per index:

• Create Alias: Add an alias pointing to the current index, with optional filter and routing
• Switch Alias: Atomically move an alias from one index to another (zero-downtime reindexing)
• Remove Alias: Delete an alias without affecting the underlying index or data

Aliases allow you to query abstract names that can be remapped without application changes.

Indices Management & Monitor

Click the Indices tab to view the indices list, you can view the index name, document count, state, health and other index information, you can also:

• Create the index by clicking the New Index button on the right top,
• Delete the index by clicking the ... in the Actions column and select the Delete option,
• Close/open the index by clicking the ... in the Actions column and select the Close/Open option,
• Refresh the index by clicking the Refresh button on the right top.
• Remove the alias by clicking the icon in the Aliases column and select the Remove Alias option.
• Switch the alias by clicking the icon in the Aliases column and select the Switch Alias option.

Templates Management & Monitor

Click the Templates tab to view the templates list, you can view the template name, type, version and other template related information. You can also click Create Template button on the right top to create a new template.

Template Types

DocKit supports both template formats:

• Index Templates (composable) — The modern format with priority, multiple index patterns, and component template references
• Component Templates — Reusable building blocks (mappings, settings, aliases) that can be composed into index templates
• Legacy Templates — Older format, mapped to equivalent composable templates when possible

When creating templates, DocKit auto-detects the format based on the Elasticsearch/OpenSearch version.
