Instantiates a job.
|
|
|
|
==== Request
|
|
|
|
`PUT _ml/anomaly_detectors/<job_id>`
|
|
|
|
//===== Description
|
|
|
|
==== Path Parameters
|
|
|
|
`job_id` (required)::
|
|
(string) Identifier for the job. This identifier can contain lowercase
|
|
alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must
|
|
start and end with alphanumeric characters.
|
|
|
|
|
|
==== Request Body
|
|
|
|
`analysis_config`::
|
|
(object) The analysis configuration, which specifies how to analyze the data.
|
|
See <<ml-analysisconfig, analysis configuration objects>>.
|
|
|
|
`analysis_limits`::
|
|
(object) Specifies runtime limits for the job. See
|
|
<<ml-apilimits,analysis limits>>.
|
|
|
|
`background_persist_interval`::
|
|
(time units) Advanced configuration option. The time between each periodic
|
|
persistence of the model. See <<ml-job-resource>>.
|
|
|
|
`custom_settings`::
|
|
(object) Advanced configuration option. Contains custom meta data about the
|
|
job. See <<ml-job-resource>>.
|
|
|
|
`data_description` (required)::
|
|
(object) Describes the format of the input data. This object is required, but
|
|
it can be empty (`{}`). See <<ml-datadescription,data description objects>>.

|
|
`description`::
|
|
(string) A description of the job.
|
|
|
|
`groups`::
|
|
(array of strings) A list of job groups. See <<ml-job-resource>>.
|
|
|
|
`model_plot_config`::
|
|
(object) Advanced configuration option. Specifies to store model information
|
|
along with the results. This adds overhead to the performance of the system
|
|
and is not feasible for jobs with many entities, see <<ml-apimodelplotconfig>>.
|
|
|
|
`model_snapshot_retention_days`::
|
|
(long) The time in days that model snapshots are retained for the job.
|
|
Older snapshots are deleted. The default value is `1`, which means snapshots
|
|
are retained for one day (twenty-four hours).
|
|
|
|
`renormalization_window_days`::
|
|
(long) Advanced configuration option. The period over which adjustments to the
|
|
score are applied, as new data is seen. See <<ml-job-resource>>.
|
|
|
|
`results_index_name`::
|
|
(string) A text string that affects the name of the {ml} results index. The
|
|
default value is `shared`, which generates an index named `.ml-anomalies-shared`.
|
|
|
|
`results_retention_days`::
|
|
(long) Advanced configuration option. The number of days for which job results
|
|
are retained. See <<ml-job-resource>>.
|
|
|
|

|
|
The following example creates the `total-requests` job:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
PUT _ml/anomaly_detectors/total-requests
|
|
{
|
|
"description" : "Total sum of requests",
|
|
"analysis_config" : {
|
|
"bucket_span":"10m",
|
|
"detectors": [
|
|
{
|
|
"detector_description": "Sum of total",
|
|
"function": "sum",
|
|
"field_name": "total"
|
|
}
|
|
]
|
|
},
|
|
"data_description" : {
|
|
"time_field":"timestamp",
|
|
"time_format": "epoch_ms"
|
|
}
|
|
}
|
