Body Required

• allow_lazy_open boolean

  Advanced configuration option. Specifies whether this job can open when there is insufficient machine learning node capacity for it to be immediately assigned to a node. By default, if a machine learning node with capacity to run the job cannot immediately be found, the open anomaly detection jobs API returns an error. However, this is also subject to the cluster-wide xpack.ml.max_lazy_ml_nodes setting. If this option is set to true, the open anomaly detection jobs API does not return an error and the job waits in the opening state until sufficient machine learning node capacity is available.

• analysis_config object Required

  Additional properties are allowed.

  Hide analysis_config attributes Show analysis_config attributes object

  • bucket_span string

    A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • categorization_analyzer string | object

    One of:

    _types:CategorizationAnalyzer string _types:CategorizationAnalyzerDefinition object

    Hide attributes Show attributes

    • char_filter array

      One or more character filters. In addition to the built-in character filters, other plugins can provide more character filters. If this property is not specified, no character filters are applied prior to categorization. If you are customizing some other aspect of the analyzer and you need to achieve the equivalent of categorization_filters (which are not permitted when some other aspect of the analyzer is customized), add them here as pattern replace character filters.

    • filter array

      One or more token filters. In addition to the built-in token filters, other plugins can provide more token filters. If this property is not specified, no token filters are applied prior to categorization.

      External documentation

    • tokenizer object | string

      The name or definition of the tokenizer to use after character filters are applied. This property is compulsory if categorization_analyzer is specified as an object. Machine learning provides a tokenizer called ml_standard that tokenizes in a way that has been determined to produce good categorization results on a variety of log file formats for logs in English. If you want to use that tokenizer but change the character or token filters, specify "tokenizer": "ml_standard" in your categorization_analyzer. Additionally, the ml_classic tokenizer is available, which tokenizes in the same way as the non-customizable tokenizer in old versions of the product (before 6.2). ml_classic was the default categorization tokenizer in versions 6.2 to 7.13, so if you need categorization identical to the default for jobs created in these versions, specify "tokenizer": "ml_classic" in your categorization_analyzer.

      One of:

      object-1 object string-2 string

      Additional properties are allowed.

  • categorization_field_name string

    Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

  • categorization_filters array[string]

    If categorization_field_name is specified, you can also define optional filters. This property expects an array of regular expressions. The expressions are used to filter out matching sequences from the categorization field values. You can use this functionality to fine tune the categorization by excluding sequences from consideration when categories are defined. For example, you can exclude SQL statements that appear in your log files. This property cannot be used at the same time as categorization_analyzer. If you only want to define simple regular expression filters that are applied prior to tokenization, setting this property is the easiest method. If you also want to customize the tokenizer or post-tokenization filtering, use the categorization_analyzer property instead and include the filters as pattern_replace character filters. The effect is exactly the same.

  • detectors array[object] Required

    Detector configuration objects specify which data fields a job analyzes. They also specify which analytical functions are used. You can specify multiple detectors for a job. If the detectors array does not contain at least one detector, no analysis can occur and an error is returned.

    Hide detectors attributes Show detectors attributes object

    • by_field_name string

      Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

    • custom_rules array[object]

      Custom rules enable you to customize the way detectors operate. For example, a rule may dictate conditions under which results should be skipped. Kibana refers to custom rules as job rules.

      Hide custom_rules attributes Show custom_rules attributes object

      • actions array[string]

        The set of actions to be triggered when the rule applies. If more than one action is specified the effects of all actions are combined.

        Values are skip_result or skip_model_update.

      • conditions array[object]

        An array of numeric conditions when the rule applies. A rule must either have a non-empty scope or at least one condition. Multiple conditions are combined together with a logical AND.

        Additional properties are allowed.

      • scope object

        A scope of series where the rule applies. A rule must either have a non-empty scope or at least one condition. By default, the scope includes all series. Scoping is allowed for any of the fields that are also specified in by_field_name, over_field_name, or partition_field_name.

        Hide scope attribute Show scope attribute object

        • * object Additional properties

          Additional properties are allowed.

    • detector_description string

      A description of the detector.

    • detector_index number

      A unique identifier for the detector. This identifier is based on the order of the detectors in the analysis_config, starting at zero. If you specify a value for this property, it is ignored.

    • exclude_frequent string

      Values are all, none, by, or over.

    • field_name string

      Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

    • function string

      The analysis function that is used. For example, count, rare, mean, min, max, or sum.

    • over_field_name string

      Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

    • partition_field_name string

      Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

    • use_null boolean

      Defines whether a new series is used as the null series when there is no value for the by or partition fields.

  • influencers array[string]

    Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

  • latency string

    A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • model_prune_window string

    A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • multivariate_by_fields boolean

    This functionality is reserved for internal use. It is not supported for use in customer environments and is not subject to the support SLA of official GA features. If set to true, the analysis will automatically find correlations between metrics for a given by field value and report anomalies when those correlations cease to hold. For example, suppose CPU and memory usage on host A is usually highly correlated with the same metrics on host B. Perhaps this correlation occurs because they are running a load-balanced application. If you enable this property, anomalies will be reported when, for example, CPU usage on host A is high and the value of CPU usage on host B is low. That is to say, you’ll see an anomaly when the CPU of host A is unusual given the CPU of host B. To use the multivariate_by_fields property, you must also specify by_field_name in your detector.

  • per_partition_categorization object

    Additional properties are allowed.

    Hide per_partition_categorization attributes Show per_partition_categorization attributes object

    • enabled boolean

      To enable this setting, you must also set the partition_field_name property to the same value in every detector that uses the keyword mlcategory. Otherwise, job creation fails.

    • stop_on_warn boolean

      This setting can be set to true only if per-partition categorization is enabled. If true, both categorization and subsequent anomaly detection stops for partitions where the categorization status changes to warn. This setting makes it viable to have a job where it is expected that categorization works well for some partitions but not others; you do not pay the cost of bad categorization forever in the partitions where it works badly.

  • summary_count_field_name string

    Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

• analysis_limits object

  Additional properties are allowed.

  Hide analysis_limits attributes Show analysis_limits attributes object

  • categorization_examples_limit number

    The maximum number of examples stored per category in memory and in the results data store. If you increase this value, more examples are available, however it requires that you have more storage available. If you set this value to 0, no examples are stored. NOTE: The categorization_examples_limit applies only to analysis that uses categorization.

  • model_memory_limit string

    The approximate maximum amount of memory resources that are required for analytical processing. Once this limit is approached, data pruning becomes more aggressive. Upon exceeding this limit, new entities are not modeled. If the xpack.ml.max_model_memory_limit setting has a value greater than 0 and less than 1024mb, that value is used instead of the default. The default value is relatively small to ensure that high resource usage is a conscious decision. If you have jobs that are expected to analyze high cardinality fields, you will likely need to use a higher value. If you specify a number instead of a string, the units are assumed to be MiB. Specifying a string is recommended for clarity. If you specify a byte size unit of b or kb and the number does not equate to a discrete number of megabytes, it is rounded down to the closest MiB. The minimum valid value is 1 MiB. If you specify a value less than 1 MiB, an error occurs. If you specify a value for the xpack.ml.max_model_memory_limit setting, an error occurs when you try to create jobs that have model_memory_limit values greater than that setting value.

• background_persist_interval string

  A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

• custom_settings object

  Custom metadata about the job

  Additional properties are allowed.

• daily_model_snapshot_retention_after_days number

  Advanced configuration option, which affects the automatic removal of old model snapshots for this job. It specifies a period of time (in days) after which only the first snapshot per day is retained. This period is relative to the timestamp of the most recent snapshot for this job. Valid values range from 0 to model_snapshot_retention_days.

• data_description object Required

  Additional properties are allowed.

  Hide data_description attributes Show data_description attributes object

  • format string

    Only JSON format is supported at this time.

  • time_field string

    Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.

  • time_format string

    The time format, which can be epoch, epoch_ms, or a custom pattern. The value epoch refers to UNIX or Epoch time (the number of seconds since 1 Jan 1970). The value epoch_ms indicates that time is measured in milliseconds since the epoch. The epoch and epoch_ms time formats accept either integer or real values. Custom patterns must conform to the Java DateTimeFormatter class. When you use date-time formatting patterns, it is recommended that you provide the full date, time and time zone. For example: yyyy-MM-dd'T'HH:mm:ssX. If the pattern that you specify is not sufficient to produce a complete timestamp, job creation fails.

  • field_delimiter string
• datafeed_config object

  Additional properties are allowed.

  Hide datafeed_config attributes Show datafeed_config attributes object

    • enabled boolean Required

      Specifies whether the datafeed periodically checks for delayed data.

  • frequency string

    A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • indices string | array[string]
  • indices_options object

    Additional properties are allowed.

    Hide indices_options attributes Show indices_options attributes object

    • allow_no_indices boolean

      If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

    • expand_wildcards string | array[string]
    • ignore_unavailable boolean

      If true, missing or closed indices are not included in the response.

    • ignore_throttled boolean

      If true, concrete, expanded or aliased indices are ignored when frozen.

  • job_id string
  • max_empty_searches number

    If a real-time datafeed has never seen any data (including during any initial training period) then it will automatically stop itself and close its associated job after this many real-time searches that return no documents. In other words, it will stop after frequency times max_empty_searches of real-time operation. If not set then a datafeed with no end time that sees no data will remain started until it is explicitly stopped.

  Advanced configuration option. The period of time (in days) that results are retained. Age is calculated relative to the timestamp of the latest bucket result. If this property has a non-null value, once per day at 00:30 (server time), results that are the specified number of days older than the latest bucket result are deleted from Elasticsearch. The default value is null, which means all results are retained. Annotations generated by the system also count as results for retention purposes; they are deleted after the same number of days as results. Annotations added by users are retained forever.
