Get node statistics
Get statistics for nodes in a cluster. By default, all stats are returned. You can limit the returned information by using metrics.
Path parameters
-
Limit the information returned to the specified metrics
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 cluster, index, or shard level.
Values are
cluster
,indices
, orshards
. -
master_timeout string
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
-
timeout string
Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.
-
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.
