Profile

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:

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

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

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