# Profile

The profile API operation returns runtime information about ML tasks and models. The profile operation can help debug model issues at runtime. 

## The number of requests returned

By default, the Profile API monitors the last 100 requests. To change the number of monitoring requests, update the following cluster setting:

```json
PUT _cluster/settings
{
  "persistent" : {
    "plugins.ml_commons.monitoring_request_count" : 1000000 
  }
}
```

To clear all monitoring requests, set `plugins.ml_commons.monitoring_request_count` to `0`. 

## Path and HTTP methods

```json
GET /_plugins/_ml/profile
GET /_plugins/_ml/profile/models
GET /_plugins/_ml/profile/models/<model_id>
GET /_plugins/_ml/profile/tasks
GET /_plugins/_ml/profile/tasks/<task_id>
```

## Path parameters

Parameter | Data type | Description
:--- | :--- | :---
`model_id` | String | Returns runtime data for a specific model. You can provide multiple model IDs as comma-separated values to retrieve multiple model profiles.
`task_id`| String | Returns runtime data for a specific task. You can provide multiple task IDs as comma-separated values to retrieve multiple task profiles.

### Request fields

All profile body request fields are optional.

Field | Data type | Description
:--- | :--- | :--- 
`node_ids` | String | Returns all tasks and profiles from a specific node. 
`model_ids` | String | Returns runtime data for a specific model. You can string together multiple model IDs to return multiple model profiles.
`task_ids` | String | Returns runtime data for a specific task. You can string together multiple task IDs to return multiple task profiles.
`return_all_tasks` | Boolean | Determines whether or not a request returns all tasks. When set to `false`, task profiles are left out of the response.
`return_all_models` | Boolean | Determines whether or not a profile request returns all models. When set to `false`, model profiles are left out of the response.

#### Example request: Returning all tasks and models on a specific node

```json
GET /_plugins/_ml/profile
{
  "node_ids": ["KzONM8c8T4Od-NoUANQNGg"],
  "return_all_tasks": true,
  "return_all_models": true
}
```
