The API returns the following information:
The API returns the following information about the operational progress of a
job:
`jobs`::
(array) An array of {anomaly-job} statistics objects.
`assignment_explanation`::
(string) For open jobs only, contains messages relating to the selection of a
node to run the job.
[[datacounts]]`data_counts`::
(object) An object that describes the quantity of input to the job and any
related error counts. The `data_count` values are cumulative for the lifetime of
a job. If a model snapshot is reverted or old results are deleted, the job
counts are not reset.
`data_counts`.`bucket_count`:::
(long) The number of bucket results produced by the job.
`data_counts`.`earliest_record_timestamp`:::
(date) The timestamp of the earliest chronologically input document.
`data_counts`.`empty_bucket_count`:::
(long) The number of buckets which did not contain any data. If your data
contains many empty buckets, consider increasing your `bucket_span` or using
functions that are tolerant to gaps in data such as `mean`, `non_null_sum` or
`non_zero_count`.
`data_counts`.`input_bytes`:::
(long) The number of raw bytes read by the job.
`data_counts`.`input_field_count`:::
(long) The total number of fields in input documents posted to the job. This
count includes fields that are not used in the analysis. However, be aware that
if you are using a {dfeed}, it extracts only the required fields from the
documents it retrieves before posting them to the job.
`data_counts`.`input_record_count`:::
(long) The number of data records read by the job.
`data_counts`.`invalid_date_count`:::
(long) The number of records with either a missing date field or a date that
could not be parsed.
`data_counts`.`job_id`:::
(string)
include::{docdir}/ml/ml-shared.asciidoc[tag=job-id-anomaly-detection]
`data_counts`.`last_data_time`:::
(date) The timestamp at which data was last analyzed, according to server time.
`data_counts`.`latest_empty_bucket_timestamp`:::
(date) The timestamp of the last bucket that did not contain any data.
`data_counts`.`latest_record_timestamp`:::
(date) The timestamp of the latest chronologically input document.
`data_counts`.`latest_sparse_bucket_timestamp`:::
(date) The timestamp of the last bucket that was considered sparse.
`data_counts`.`missing_field_count`:::
(long) The number of input documents that are missing a field that the job is
configured to analyze. Input documents with missing fields are still processed
because it is possible that not all fields are missing. The value of
`processed_record_count` includes this count.
+
--
NOTE: If you are using {dfeeds} or posting data to the job in JSON format, a
high `missing_field_count` is often not an indication of data issues. It is not
necessarily a cause for concern.
--
`data_counts`.`out_of_order_timestamp_count`:::
(long) The number of input documents that are out of time sequence and outside
of the latency window. This information is applicable only when you provide data
to the job by using the <<ml-post-data,post data API>>. These out of order
documents are discarded, since jobs require time series data to be in ascending
chronological order.
`data_counts`.`processed_field_count`:::
(long) The total number of fields in all the documents that have been processed
by the job. Only fields that are specified in the detector configuration object
contribute to this count. The time stamp is not included in this count.
`data_counts`.`processed_record_count`:::
(long) The number of input documents that have been processed by the job. This
value includes documents with missing fields, since they are nonetheless
analyzed. If you use {dfeeds} and have aggregations in your search query, the
`processed_record_count` will be the number of aggregation results processed,
not the number of {es} documents.
`data_counts`.`sparse_bucket_count`:::
(long) The number of buckets that contained few data points compared to the
expected number of data points. If your data contains many sparse buckets,
consider using a longer `bucket_span`.
[[forecastsstats]]`forecasts_stats`::
(object) An object that provides statistical information about forecasts
of this job. It has the following properties:
+
--
NOTE: `memory_bytes`, `records`, `processing_time_ms` and `status` require at
least one forecast. Otherwise, these fields are omitted.
--
`forecasts_stats`.`forecasted_jobs`:::
(long) The number of jobs that have at least one forecast.
`forecasts_stats`.`memory_bytes`:::
(object) Statistics about the memory usage: minimum, maximum, average and total.
`forecasts_stats`.`processing_time_ms`:::
(object) Statistics about the forecast runtime in milliseconds: minimum, maximum, average and total.
`forecasts_stats`.`records`:::
(object) Statistics about the number of forecast records: minimum, maximum,
average and total.
`forecasts_stats`.`status`:::
(object) Counts per forecast status, for example: `{"finished" : 2}`.
`forecasts_stats`.`total`:::
(long) The number of forecasts currently available for this model.
`job_id`::
(string)

model. It has the following properties:
`model_size_stats`.`bucket_allocation_failures_count`:::

processed due to insufficient model memory. This situation is also signified
by a `hard_limit: memory_status` property value.
`model_size_stats`.`job_id`:::
(string)
include::{docdir}/ml/ml-shared.asciidoc[tag=job-id-anomaly-detection]
`model_size_stats`.`log_time`:::
(date) The timestamp of the `model_size_stats` according to server time.
`model_size_stats`.`memory_status`:::
(string) The status of the mathematical models. This property can have one of
the following values:
+
--
* `ok`: The models stayed below the configured value.
* `soft_limit`: The models used more than 60% of the configured memory limit and
older unused models will be pruned to free up space.
* `hard_limit`: The models used more space than the configured memory limit. As
a result, not all incoming data was processed.
--
`model_size_stats`.`model_bytes`:::
(long) The number of bytes of memory used by the models. This is the maximum
value since the last time the model was persisted. If the job is closed,
this value indicates the latest size.

allocation failure.
`model_size_stats`.`model_bytes_memory_limit`:::

(string) For internal use. The type of result.
`model_size_stats`.`total_by_field_count`:::
(long) The number of `by` field values that were analyzed by the models.

partition.

(string) The unique identifier of the node.
`node`.`name`:::
(string) The node name.
`node`.`transport_address`:::
(string) The host and port where transport HTTP connections are accepted.
`open_time`::
(string) For open jobs only, the elapsed time for which the job has been open.
For example, `28746386s`.
`state`::
(string) The status of the job, which can be one of the following values:
+
--
* `closed`: The job finished successfully with its model state persisted. The
job must be opened before it can accept further data.
* `closing`: The job close action is in progress and has not yet completed. A
closing job cannot accept further data.
* `failed`: The job did not finish successfully due to an error. This situation
can occur due to invalid input data. If the job had irrevocably failed, it must
be force closed and then deleted. If the {dfeed} can be corrected, the job can
be closed and then re-opened.
* `opened`: The job is available to receive and process data.
* `opening`: The job open action is in progress and has not yet completed.
