Job statistics

edit

Job statistics

edit

The get job statistics API provides information about the operational progress of a job.

assignment_explanation

(string) For open jobs only, contains messages relating to the selection of a node to run the job.

data_counts

(object) An object that describes the number of records processed and any related error counts. See data counts objects.

job_id

(string) A unique identifier for the job.

model_size_stats

(object) An object that provides information about the size and contents of the model. See model size stats objects.

forecasts_stats

(object) An object that provides statistical information about forecasts of this job. See forecasts stats objects.

timing_stats

(object) An object that provides statistical information about timing aspect of this job. See timing stats objects.

node

(object) For open jobs only, contains information about the node where the job runs. See node object.

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:

opened: The job is available to receive and process data.
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 datafeed can be corrected, the job can be closed and then re-opened.
opening: The job open action is in progress and has not yet completed.

Data Counts Objects

edit

The data_counts object describes the number of records processed 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.

bucket_count: (long) The number of bucket results produced by the job.
earliest_record_timestamp: (date) The timestamp of the earliest chronologically input document.
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.
input_bytes: (long) The number of raw bytes read by the job.
input_field_count: (long) The total number of record fields read by the job. This count includes fields that are not used in the analysis.
input_record_count: (long) The number of data records read by the job.
invalid_date_count: (long) The number of records with either a missing date field or a date that could not be parsed.
job_id: (string) A unique identifier for the job.
last_data_time: (date) The timestamp at which data was last analyzed, according to server time.
latest_empty_bucket_timestamp: (date) The timestamp of the last bucket that did not contain any data.
latest_record_timestamp: (date) The timestamp of the latest chronologically input document.
latest_sparse_bucket_timestamp: (date) The timestamp of the last bucket that was considered sparse.
missing_field_count: (long) The number of records that are missing a field that the job is configured to analyze. Records 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.

If you are using datafeeds 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.

out_of_order_timestamp_count: (long) The number of records 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 post data API. These out of order records are discarded, since jobs require time series data to be in ascending chronological order.
processed_field_count: (long) The total number of fields in all the records 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.
processed_record_count: (long) The number of records that have been processed by the job. This value includes records with missing fields, since they are nonetheless analyzed.
If you use datafeeds and have aggregations in your search query, the processed_record_count will be the number of aggregated records processed, not the number of Elasticsearch documents.
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.

Model Size Stats Objects

edit

The model_size_stats object has the following properties:

bucket_allocation_failures_count

(long) The number of buckets for which new entities in incoming data were not processed due to insufficient model memory. This situation is also signified by a hard_limit: memory_status property value.

job_id

(string) A numerical character string that uniquely identifies the job.

log_time

(date) The timestamp of the model_size_stats according to server time.

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_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.

result_type

(string) For internal use. The type of result.

total_by_field_count

(long) The number of by field values that were analyzed by the models.+

The by field values are counted separately for each detector and partition.

total_over_field_count: (long) The number of over field values that were analyzed by the models.+

The over field values are counted separately for each detector and partition.

total_partition_field_count: (long) The number of partition field values that were analyzed by the models.
timestamp: (date) The timestamp of the model_size_stats according to the timestamp of the data.

Forecasts Stats Objects

edit

The forecasts_stats object shows statistics about forecasts. It has the following properties:

total: (long) The number of forecasts currently available for this model.
forecasted_jobs: (long) The number of jobs that have at least one forecast.
memory_bytes: (object) Statistics about the memory usage: minimum, maximum, average and total.
records: (object) Statistics about the number of forecast records: minimum, maximum, average and total.
processing_time_ms: (object) Statistics about the forecast runtime in milliseconds: minimum, maximum, average and total.
status: (object) Counts per forecast status, for example: {"finished" : 2}.

memory_bytes, records, processing_time_ms and status require at least 1 forecast, otherwise these fields are omitted.

Timing Stats Objects

edit

The timing_stats object shows timing-related statistics about the job’s progress. It has the following properties:

job_id: (string) A numerical character string that uniquely identifies the job.
bucket_count: (long) The number of buckets processed.
minimum_bucket_processing_time_ms: (double) Minimum among all bucket processing times in milliseconds.
maximum_bucket_processing_time_ms: (double) Maximum among all bucket processing times in milliseconds.
average_bucket_processing_time_ms: (double) Average of all bucket processing times in milliseconds.
exponential_average_bucket_processing_time_ms: (double) Exponential moving average of all bucket processing times in milliseconds.

Node Objects

edit

The node objects contains properties for the node that runs the job. This information is available only for open jobs.

id: (string) The unique identifier of the node.
name: (string) The node name.
ephemeral_id: (string) The ephemeral id of the node.
transport_address: (string) The host and port where transport HTTP connections are accepted.
attributes: (object) For example, {"ml.machine_memory": "17179869184"}.
