## Create anomaly detector
Introduced 1.0
{: .label .label-purple }
Creates an anomaly detector.
This command creates a single-flow detector named `test-detector` that finds anomalies based on the sum of the `value` field:

You can specify a maximum of two category fields:
```json
"category_field": [
"ip"
]
```
```json
"category_field": [
"ip", "error_type"
]
```
You can specify the following options.
Options | Description | Type | Required
:--- | :--- |:--- |:--- |
`name` | The name of the detector. | `string` | Yes
`description` | A description of the detector. | `string` | Yes
`time_field` | The name of the time field. | `string` | Yes
`indices` | A list of indices to use as the data source. | `list` | Yes
`feature_attributes` | Specify a `feature_name`, set the `enabled` parameter to `true`, and specify an aggregation query. | `list` | Yes
`filter_query` | Provide an optional filter query for your feature. | `object` | No
`detection_interval` | The time interval for your anomaly detector. | `object` | Yes
`window_delay` | Add extra processing time for data collection. | `object` | No
`category_field` | Categorizes or slices data with a dimension. Similar to `GROUP BY` in SQL. | `list` | No

## Update detector
Introduced 1.0
{: .label .label-purple }
Updates a detector with any changes, including the description or adding or removing of features.
To update a detector, you need to first stop both real-time detection and historical analysis.
You can't update a category field.

## Start detector job
Introduced 1.0
{: .label .label-purple }
Starts a real-time or historical anomaly detector job.
To start a real-time detector job:
#### Request
```json
POST _plugins/_anomaly_detection/detectors/<detectorId>/_start
```
#### Sample response
```json
{
"_id": "VEHKTXwBwf_U8gjUXY2s",
"_version": 3,
"_seq_no": 6,
"_primary_term": 1
}
```
The `_id` represents the real-time job ID, which is the same as the detector ID.
To start historical analysis:
```json
POST _plugins/_anomaly_detection/detectors/<detectorId>/_start
{
"start_time": 1633048868000,
"end_time": 1633394468000
}
```
#### Sample response
```json
{
"_id": "f9DsTXwB6HknB84SoRTY",
"_version": 1,
"_seq_no": 958,
"_primary_term": 1
}
```
The `_id` represents the historical batch task ID, which is a random universally unique identifier (UUID).

## Search detector result
Introduced 1.0
{: .label .label-purple }
Returns all results for a search query.
To search anomaly results for `grade` greater than 0 for real-time analysis:
#### Request
```json
GET _plugins/_anomaly_detection/detectors/results/_search
POST _plugins/_anomaly_detection/detectors/results/_search
{
"query": {
"bool": {
"filter": [

}
}
}
],
"must_not": [
{
"exists": {
"field": "task_id"

}
}
}
```
Because real-time analysis doesn't have a batch task, the task ID in the anomaly result is null.

You can run historical analysis as many times as you like. So, multiple tasks might exist for the same detector.
You can search for the latest historical batch task first and then search the historical batch task results.
To search anomaly results for `grade` greater than 0 for historical analysis with the `task_id`:
#### Request

The `model_count` parameter shows the total number of models running on each node’s memory.
For historical analysis, you see the values for the following fields:
- `ad_total_batch_task_execution_count`
- `ad_executing_batch_task_count`
- `ad_canceled_batch_task_count`
- `ad_batch_task_failure_count`
If haven't run any historical analysis, these values show up as 0.

## Profile detector
Introduced 1.0
{: .label .label-purple }
Returns information related to the current state of the detector and memory usage, including current errors and shingle size, to help troubleshoot the detector.
This command helps locate logs by identifying the nodes that run the anomaly detector job for each detector.
It also helps track the initialization percentage, the required shingles, and the estimated time left.

You can see the `ad_task` field only for historical analysis.
The `model_count` parameter shows the total number of models that a detector runs on each node’s memory. This is useful if you have several models running on your cluster and want to know the count.
If you configured the category field, you can see the number of unique values in the field and all active entities with models running in memory.
You can use this data to estimate how much memory is required for anomaly detection so you can decide how to size your cluster. For example, if a detector has one million entities and only 10 of them are active in memory, you need to scale your cluster up or out.
For a single-entity detector:

The `total_entities` parameter shows you the total number of entities including the number of category fields for a detector.
Getting the total count of entities is an expensive operation for real-time analysis of a detector with more than one category field. By default, for a real-time detection profile, a detector counts the number of entities up to a value of 10,000. For historical analysis, the anomaly detection plugin only detects the top 1,000 entities by default and caches the top entities in memory, so it doesn't cost much to get the total count of entities for historical analysis.
The `profile` operation also provides information about each entity, such as the entity’s `last_sample_timestamp` and `last_active_timestamp`. `last_sample_timestamp` shows the last document in the input data source index containing the entity, while `last_active_timestamp` shows the timestamp when the entity’s model was last seen in the model cache.
If there are no anomaly results for an entity, either the entity doesn't have any sample data or its model is removed from the model cache.

To get profile information for only historical analysis, specify `ad_task`.
Specifying `_all` is an expensive operation for multi-category high cardinality detectors.
