Path parameters

• node_id string | array[string] Required

  Comma-separated list of node IDs or names used to limit returned information.

• metric string | array[string] Required

  Limits the information returned to the specific metrics.

• index_metric string | array[string] Required

  Limit the information returned for indices metric to the specific index metrics. It can be used only if indices (or all) metric is specified.

Query parameters

• completion_fields string | array[string]

  Comma-separated list or wildcard expressions of fields to include in fielddata and suggest statistics.

• fielddata_fields string | array[string]

  Comma-separated list or wildcard expressions of fields to include in fielddata statistics.

• fields string | array[string]

  Comma-separated list or wildcard expressions of fields to include in the statistics.

• groups boolean

  Comma-separated list of search groups to include in the search statistics.

• include_segment_file_sizes boolean

  If true, the call reports the aggregated disk usage of each one of the Lucene index files (only applies if segment stats are requested).

• level string

  Indicates whether statistics are aggregated at the node, indices, or shards level.

  Values are cluster, indices, or shards.

• timeout string

  Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

  External documentation
• types array[string]

  A comma-separated list of document types for the indexing index metric.

• include_unloaded_segments boolean

  If true, the response includes information from segments that are not loaded into memory.
