You do not need to configure any settings to use machine learning. It is enabled by default.
true(default) to identify the node as a machine learning node.
If set to
elasticsearch.yml, the node cannot run jobs. If set to
xpack.ml.enabledis set to
node.mlsetting is ignored and the node cannot run jobs. If you want to run jobs, there must be at least one machine learning node in your cluster.
On dedicated coordinating nodes or dedicated master nodes, disable the
true(default) to enable machine learning on the node.
If set to
elasticsearch.yml, the machine learning APIs are disabled on the node. Therefore the node cannot open jobs, start datafeeds, or receive transport (internal) communication requests related to machine learning APIs. It also affects all Kibana instances that connect to this Elasticsearch instance; you do not need to disable machine learning in those
kibana.ymlfiles. For more information about disabling machine learning in specific Kibana instances, see Kibana Machine Learning Settings.
If you want to use machine learning features in your cluster, you must have
trueon all master-eligible nodes. This is the default behavior.
The maximum number of jobs that can run on a node. Defaults to
model_memory_limitproperty value that can be set for any job on this node. If you try to create a job with a
model_memory_limitproperty value that is greater than this setting value, an error occurs. Existing jobs are not affected when you update this setting. For more information about the
model_memory_limitproperty, see Analysis Limits.
The maximum number of jobs that can concurrently be in the
openingstate on each node. Typically, jobs spend a small amount of time in this state before they move to
openstate. Jobs that must restore large models when they are opening spend more time in the
openingstate. Defaults to
