ML Commons cluster settings

This page provides an overview of opensearch.yml settings that can be configured for the ML commons plugin.

Run tasks and models on ML nodes only

Setting

plugins.ml_commons.only_run_on_ml_node: false

Description

If true, ML Commons tasks and models run machine learning (ML) tasks on ML nodes only. If false, tasks and models run on ML nodes first. If no ML nodes exist, tasks and models run on data nodes. Don't set as "false" on production cluster.

Values

• Default value: false
• Value range: true or false

Dispatch tasks to ML node with least load

Setting

plugins.ml_commons.task_dispatch_policy: round_robin

Description

round_robin dispatches ML tasks to ML nodes using round robin routing. least_load gathers all an ML nodes' runtime information, like JVM heap memory usage and running tasks, then dispatches tasks to the ML node with the least load.

Values

• Dafault value: round_robin
• Value range: round_robin or least_load

Set sync up job intervals

Setting

plugins.ml_commons.sync_up_job_interval_in_seconds: 10

Description

When returning runtime information with the profile API, ML Commons will run a regular sync up job to sync up newly loaded or unloaded models on each node. When set to 0, ML Commons immediately stops sync up jobs.

Values

• Default value: 10
• Value range: [0, 86,400]

Predict monitoring requests

Setting

plugins.ml_commons.monitoring_request_count: 100

Description

Controls how many upload model tasks can run in parallel on one node. If set to 0, you cannot upload models to any node.

Value range

• Default value: 100
• Value range: [0, 100,000,000]

Upload model tasks per node

Setting

plugins.ml_commons.max_upload_model_tasks_per_node: 10

Description

Controls how many upload model tasks can run in parallel on one node. If set to 0, you cannot upload models to any node.

Values

• Default value: 10
• Value range: [0, 10]

Load model tasks per node

Setting

plugins.ml_commons.max_load_model_tasks_per_node: 10

Description

Controls how many load model tasks can run in parallel on one node. If set as 0, you cannot load models to any node.

Values

• Default value: 10
• Value range: [0, 10]

Add trusted URL

Setting

plugins.ml_commons.trusted_url_regex: ^(https?\|ftp\|file)://[-a-zA-Z0-9+&@#/%?=~_\|!:,.;]*[-a-zA-Z0-9+&@#/%=~_\|]

Description

The default value allows uploading a model file from any http/https/ftp/local file. You can change this value to restrict trusted model URL

Values

• Default value: ^(https?\|ftp\|file)://[-a-zA-Z0-9+&@#/%?=~_\|!:,.;]*[-a-zA-Z0-9+&@#/%=~_\|]
• Value range: Java regular expression (regex) string
