`assignment_explanation`:::
(string)
For running jobs only, contains messages relating to the selection of a node to 
run the job.

//Begin data_counts
`data_counts`:::
(object)
An object that provides counts for the quantity of documents skipped, used in
training, or available for testing.
+
.Properties of `data_counts`
[%collapsible%open]
=====
`skipped_docs_count`:::
(integer)
The number of documents that are skipped during the analysis because they 
contained values that are not supported by the analysis. For example, 
{oldetection} does not support missing fields so it skips documents with missing 
fields. Likewise, all types of analysis skip documents that contain arrays with 
more than one element.

`test_docs_count`:::
(integer)
The number of documents that are not used for training the model and can be used 
for testing.

`training_docs_count`:::
(integer)
The number of documents that are used for training the model.
=====
//End data_counts

`id`:::
(string)
The unique identifier of the {dfanalytics-job}.

`memory_usage`:::
(Optional, object)
An object describing memory usage of the analytics. It is present only after the 
job is started and memory usage is reported.
+
.Properties of `memory_usage`
[%collapsible%open]
=====
`memory_reestimate_bytes`::::
(long)
This value is present when the `status` is `hard_limit` and it
is a new estimate of how much memory the job needs.

`peak_usage_bytes`::::
(long)
The number of bytes used at the highest peak of memory usage.

`status`::::
(string)
The memory usage status. May have one of the following values:
+
--
* `ok`: usage stayed below the limit.
* `hard_limit`: usage surpassed the configured memory limit.
--

`timestamp`::::
(date)
The timestamp when memory usage was calculated.
=====

`node`:::
(object)
Contains properties for the node that runs the job. This information is 
available only for running jobs.
+
.Properties of `node`
[%collapsible%open]
=====
`attributes`:::
(object)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=node-attributes]

`ephemeral_id`:::
(string)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=node-ephemeral-id]

`id`:::
(string)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=node-id]

`name`:::
(string)
The node name.

`transport_address`:::
(string)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=node-transport-address]
=====

`progress`:::
(array) The progress report of the {dfanalytics-job} by phase.
+
.Properties of phase objects
[%collapsible%open]
=====
`phase`:::
(string) Defines the phase of the {dfanalytics-job}. Possible phases: 
* `reindexing`, 
* `loading_data`, 
* `computing_outliers` (for {oldetection} only),
* `feature_selection` (for {regression} and {classification} only),
* `coarse_parameter_search` (for {regression} and {classification} only),
* `fine_tuning_parameters` (for {regression} and {classification} only),
* `final_training` (for {regression} and {classification} only),
* `writing_results`,
* `inference` (for {regression} and {classification} only).
+
To learn more about the different phases, refer to
{ml-docs}/ml-dfa-phases.html[How a {dfanalytics} job works].
    
`progress_percent`:::
(integer) The progress that the {dfanalytics-job} has made expressed in 
percentage.
=====

`state`:::
(string) The status of the {dfanalytics-job}, which can be one of the following
values: `analyzing`, `failed`, `reindexing`, `started`, `starting`, `stopped`,
`stopping`.
