Get datafeed statistics API
editGet datafeed statistics API
editRetrieves usage information for datafeeds.
Request
editGET _ml/datafeeds/<feed_id>/_stats
GET _ml/datafeeds/<feed_id>,<feed_id>/_stats
GET _ml/datafeeds/_stats
GET _ml/datafeeds/_all/_stats
Prerequisites
edit-
If the Elasticsearch security features are enabled, you must have
monitor_ml
,monitor
,manage_ml
, ormanage
cluster privileges to use this API. See Security privileges and Machine learning security privileges.
Description
editYou can get statistics for multiple datafeeds in a single API request by using a
comma-separated list of datafeeds or a wildcard expression. You can get
statistics for all datafeeds by using _all
, by specifying *
as the
<feed_id>
, or by omitting the <feed_id>
.
If the datafeed is stopped, the only information you receive is the
datafeed_id
and the state
.
This API returns a maximum of 10,000 datafeeds.
Path parameters
edit-
<feed_id>
-
(Optional, string) Identifier for the datafeed. It can be a datafeed identifier or a wildcard expression.
If you do not specify one of these options, the API returns information about all datafeeds.
Query parameters
edit-
allow_no_datafeeds
-
(Optional, Boolean)
[7.10]
Deprecated in 7.10. Use
allow_no_match
instead. -
allow_no_match
-
(Optional, Boolean) Specifies what to do when the request:
- Contains wildcard expressions and there are no datafeeds that match.
-
Contains the
_all
string or no identifiers and there are no matches. - Contains wildcard expressions and there are only partial matches.
The default value is
true
, which returns an emptydatafeeds
array when there are no matches and the subset of results when there are partial matches. If this parameter isfalse
, the request returns a404
status code when there are no matches or only partial matches.
Response body
editThe API returns an array of datafeed count objects. All of these properties are informational; you cannot update their values.
-
assignment_explanation

-
datafeed_id
- (string) A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
-
node
-
(object) For started datafeeds only, this information pertains to the node upon which the datafeed is started.
Details
-
attributes
-
(object)
Lists node attributes such as
ml.machine_memory
orml.max_open_jobs
settings. -
ephemeral_id
- (string) The ephemeral ID of the node.
-
id
- (string) The unique identifier of the node.
-
name
-
(string)
The node name. For example,
0-o0tOo
. -
transport_address
- (string) The host and port where transport HTTP connections are accepted.
-
-
state
-
(string) The status of the datafeed, which can be one of the following values:
-
starting
: The datafeed has been requested to start but has not yet started. -
started
: The datafeed is actively receiving data. -
stopping
: The datafeed has been requested to stop gracefully and is completing its final action. -
stopped
: The datafeed is stopped and will not receive data until it is re-started.
-
-
timing_stats
-
(object) An object that provides statistical information about timing aspect of this datafeed.
Details
-
average_search_time_per_bucket_ms
- (double) The average search time per bucket, in milliseconds.
-
bucket_count
- (long) The number of buckets processed.
-
exponential_average_search_time_per_hour_ms
- (double) The exponential average search time per hour, in milliseconds.
-
job_id
- Identifier for the anomaly detection job.
-
search_count
- The number of searches run by the datafeed.
-
total_search_time_ms
- The total time the datafeed spent searching, in milliseconds.
-
Response codes
edit-
404
(Missing resources) -
If
allow_no_match
isfalse
, this code indicates that there are no resources that match the request or only partial matches for the request.
