[role="xpack"] [testenv="platinum"] [[ml-dfanalytics-resources]] === {dfanalytics-cap} job resources {dfanalytics-cap} resources relate to APIs such as <> and <>. [discrete] [[ml-dfanalytics-properties]] ==== {api-definitions-title} `analysis`:: (object) The type of analysis that is performed on the `source`. For example: `outlier_detection`. For more information, see <>. `analyzed_fields`:: (object) You can specify both `includes` and/or `excludes` patterns. If `analyzed_fields` is not set, only the relevant fields will be included. For example all the numeric fields for {oldetection}. `dest`:: (object) The destination configuration of the analysis. For more information, see <>. `id`:: (string) The unique identifier for the {dfanalytics-job}. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters. This property is informational; you cannot change the identifier for existing jobs. `model_memory_limit`:: (string) The approximate maximum amount of memory resources that are permitted for analytical processing. The default value for {dfanalytics-jobs} is `1gb`. If your `elasticsearch.yml` file contains an `xpack.ml.max_model_memory_limit` setting, an error occurs when you try to create {dfanalytics-jobs} that have `model_memory_limit` values greater than that setting. For more information, see <>. `source`:: (object) The source configuration, consisting of `index` and optionally a `query`. For more information, see <>. [[dfanalytics-types]] ==== Analysis objects {dfanalytics-cap} resources contain `analysis` objects. For example, when you create a {dfanalytics-job}, you must define the type of analysis it performs. [discrete] [[oldetection-resources]] ===== {oldetection-cap} configuration objects An {oldetection} configuration object has the following properties: [discrete] [[oldetection-properties]] ==== {api-definitions-title} `n_neighbors`:: (integer) Defines the value for how many nearest neighbors each method of {oldetection} will use to calculate its {olscore}. When the value is not set, the system will dynamically detect an appropriate value. `method`:: (string) Sets the method that {oldetection} uses. If the method is not set {oldetection} uses an ensemble of different methods and normalises and combines their individual {olscores} to obtain the overall {olscore}. Available methods are `lof`, `ldof`, `distance_kth_nn`, `distance_knn`. `feature_influence_threshold`:: (double) The minimum {olscore} that a document needs to have in order to calculate its {fiscore}. Value range: 0-1 (`0.1` by default). [[dfanalytics-dest-resources]] ==== Dest configuration objects {dfanalytics-cap} resources contain `dest` objects. For example, when you create a {dfanalytics-job}, you must define its destination. [discrete] [[dfanalytics-dest-properties]] ==== {api-definitions-title} `index`:: (string) The name of the index in which to store the results of the {dfanalytics-job}. `results_field`:: (string) The name of the field in which to store the results of the analysis. The default value is `ml`. [[dfanalytics-source-resources]] ==== Source configuration objects The `source` configuration object has the following properties: `index`:: (array) An array of index names on which to perform the analysis. It can be a single index or index pattern as well as an array of indices or patterns. `query`:: (object) The {es} query domain-specific language (DSL). This value corresponds to the query object in an {es} search POST body. All the options that are supported by {es} can be used, as this object is passed verbatim to {es}. By default, this property has the following value: `{"match_all": {}}`.
